Sort Of Trunking Solid Summing and Fillet Problem.
Read 3506 times
* July 18, 2019, 06:18:12 AM
Hi All,

I have a bunch of Solid Pieces that have edges that are intersecting and I am trying to add them into a single solid that can be filleted. I have provided the file as I began two days ago in trying to add and finish the solid together. The profiles of the lofts are also in the file.

Yesterday I was able to add them together but afterward I could not fillet all the edges. Turbo Cad was fighting me all the way. I got a long way with filleting in an order but it seems that turbo cad has a big problem with filleting when four edges meet (at least with the standard settings).

Today I tried the Trunking tool just for the mid section where there are overlapping profiles to see if that would help but the trunking tool would not do the overlapping profiles possibly because they were not a true trunk.

The lofted transitions between circles and polygonal geometries seem to be the root of this problem.

The other thing that I tried yesterday was taking all the polygonal profiles and exploding them into lines and then rounding the corners with a smooth arc then lofting between the rounded profiles. I had problems with lofting between some of them and could not complete the solid and so I did not get to try filleting the remaining edges.

Any suggestions on a method to add and fillet this type of complex geometry?

Best Regards,
Dean

It isn't a "type of intersection" problem, all multiface intersections have specific ranges of parameters.   The factors that matter: radius of individual edges, whether that radius is within the range of radiis applicable to that multiface intersection, whether or not they can be calculated concurrently or whether one is dependent on another being applied first, and different sequences of filleting will give different results.  I'd uncheck the "round vertex" option and apply them sequentially, there's usually a sequence that will work when an all-at-once attempt won't, and you'll find the particular intersection and parameters that are stopping it.  Each fillet will reduce the number of edges that can be filleted, letting you measure your progress and isolating the problem areas.  Alternatively or as a collateral measure, add two or three pieces together and fillet the appropriate edges of that part, add those (assumed) successes together and fillet the edges that result after they've been added.

Hi Murry,

I have had to do difficult fillet orders before but this one is way over the top. In some instances the same edge geometry opposite the mirror axis does not behave the same and I keep having to UNDO after toggling Round Vertex to see if it will apply the fillet or generate an error. What a pain. I am making progress but:

Here is an instance where I can't apply a fillet to the flat top with filleted sides. I sliced the top then tried to fillet. I get an error with trying to apply different radius and trying to apply with or without rounding. In other iterations of fillet order I was able to get the top but then not all the sides edges will fillet. Will I need to sweep a shape and subtract this edge?

Also at this point everything that is on the plane where the lowest fillets on the part end will not fillet. If I do the remaining two vertical fillets they result in an extended plane of a side that appears as a sharp edge that cannot be filleted.

To fix the Top so that it would fillet I had to redraw the original profile which was two circles with two lines on each side. Then I had to slice the top of the part twice once 0.1" below the top and once at .050" which was in the middle of the top and the new slice.

Then I had to create intersections for the bottom and the middle and create two new lofts one from the bottom to the middle and from the middle to the redrawn top.

This was such a pain to get the top to fillet.

Hi Dean,

Before going down the road of the frustration of slicing and redrawing study the nodes that get highlighted when you engage the Fillet Tool and click on a "top" line/node/s.... As you can see I found out why it wouldn't fillet in the attached below from the second to last file you attached:

Hi Darrel,

How do I get the program to display different colored dots? I only see blue dots.

It is a mystery how the program placed the 0.040" fillet where your arrow is on the green dot with an unfilleted edge to it without an error and required an additional fillet next to it. In any case I was able to add a .020" fillet where the blue dot on my program and was then able to fillet the top.

Is it possible that some other fillet that I did added the edge next to the fillet that caused the problem?

I see this causing a problem for tooling because If I have to add additional fillets that are smaller than the original fillet that I placed originally I will incur more tooling cost for using additional tool sizes and more machine time spent. Now I will need to use a .040" ball tool and a .080" ball tool for this project.

On the other more frustrating avenue of Slicing, exploding, and creating intersections of the midsection. Turbocad is creating Broken profiles that have missing and non-intersecting and missing lines,splines, etc. Thats not good. One of them is where the other green dot is that cannot be filleted. The original profile that I created the loft from does not have any of these issues. It seems when I filleted the area around the same axis as the other green dot it created a problem.

Hi Darrel,

Thanks for helping to diagnose this file.

That appears to be another thing that I am unable to check for. If I highlight the poly line I just get a box in my program. Is there a special selection tool to view in that way?

I have attached just the polyline profile from the original file from above by itself, do you see anything wrong with it by itself? I deleted both lofts before copying it into a new file and didn't alter it in any other way. I couldn't see anything wrong with it the vertices, they are connected when zoomed all the way in. it also extrudes an uninterrupted solid without issue. I usually extrude test profiles before lofting and when I rebuilt this file for the third time I checked each profile before lofting.

When I built the lofted geometries I was lofting to and from the same profile in different steps because I did not want it to be smooth lofts because I had to preserve thickness between this and another solid.

I don't use Mac however in one of the help forums I saw that there was a command for repair profile. I checked my version of Turbocad to see if there was a command for it and could not find it. Was it renamed?

https://turbocaddoc.atlassian.net/wiki/spaces/TMP/pages/37060693/Repair+Profile

I am thinking that if I can't see different dots to note broken profiles I will need another way to design with and that could be the repair all profiles before lofting.

Ahh thanks Jeff.

In this file I have

1.) Redrawn all profiles in polylines and made sure to close profile as the last point.
2.) Lofted between profiles, From Profile to Profile and from profile to profile using first and last profile once and inbetween profiles twice. Does this cause a broken profile after the loft?
3.) Summed the entire geometry together in one step using boolean add selected solids (which I am not sure if it is the same as MultiAdd_VB6)

Result. Still have edges I cannot fillet. Therefore it seems that there are breaks in profiles even though I closed them all. Could you confirm?

You should be able to see even though the node has no highlight in V21 as option "Close" is available (Not greyed out) if the polyline is not closed. see here the V21 help page - http://turbocaddoc.atlassian.net/wiki/spaces/TC21UG/pages/14319871/Closing+Open+Objects

Your profile is still not closed. Are you actually closing it?.
Why not use the irregular polyline tool instead as this automatically is a closed profile which is a better option for that shape details here - http://turbocaddoc.atlassian.net/wiki/spaces/TC21UG/pages/14320032/Irregular+Polygon

When I was drawing polygons with polyline I was using the Join End points of Entity to close the profile. This did not work to close the profile.

I also previously tried snapping to the end point and this did not close the profile either.

It seems like both of the above should close the profile.

I will try the tool that you recommended however due to the nature that I need to design in having to close each profile to loft and fillet will extend design time because every time I alter something I will need to close all the effected profiles again.

I have been using this Program for quite some time and it seems that only the Loft tool is really affected by this problem. Other tools are not really effected so much.

I have had some fillet issues in the past but those all included lofted profiles. Never with revolves, extrudes, sweeps, etc.

Its worth noting that to not have the start and end nodes sharing the same location.... the "Close" option joins with a line between these points. See attached

Have you checked for update of your version as it seems like you dont have the latest built of TC Pro.
You have 21.0.21.4

And the latest is 21.2.71.0 ( NB!! With start up commercial, but possible to take away after install )

Hi Torfinn,

The thought had crossed my mind about the TC version. I went to the update in the program and it said I had the latest version but now looking at the build I do not. I will download and install.

Back to this filleting issue.....

So it turns out that closing all the profiles made less of the edges able to be filleted. All 2D profiles and the Summed solid are attached in different layers. In some of the attempted fillets the fillet bends between the sections of loft where each middle loft is the same piece for the end of one loft and the beginning of another loft.

Built 21.4 was the master candidate but they changed that later.
Are you in RedSDK mode ??, as there was a fault with that built in RedSDK, 6 days after that built they make b 21.5 and the day after that again b 22.0
So, if yo are in Native Draw = RedSDK you can try switch to GDI or try to update to b 71.0 and see if the polyline close.

Did you loft the mid section which has the same profile at both ends? When Lofts are added together there is a slight deformation going on showing up as extra node/s that should not be generated. This is where filleting fails as for example the front face is inline and flat and should not have a node there.... as per the first one I made where the mid section is an extrude.
I unticked degenerative faceting in the ACIS settings so I can see the more of the facet building like the diagonals on the problem areas.

There's a way of working around some tricky fillets like this in TC.  In the pic attached I subtracted a sphere where the faces met and filleted the edges sequentially.  Once the edges were done, I subtracted the spherical face with facet editor and the result is how ACIS' internal logic finished the intersection.

MicheliDE, must you use two sets of profiles?

Henry H

Hi Henry,

Yes I cannot use a smooth loft between these profiles. It must be blocky until I fillet because there are under layers of this part and I need a very high tolerance of thickness between the exterior which this forum is about and the other parts under it.

If you think I should not use the same profile for both lofts each I could copy paste each of the middle profiles and loft separately however I have experienced strange anomalies with overlapping profiles of the same points in the past.

I will give it a try if you think it might be a better result.

Hi Darrel,

I'll try to explain what I did in the last iteration of the file.

Starting from the bottom of the file. Circle lofted to closed polygon. Same closed polygon profile lofted to midsection polygon. Same mid section polygon lofted to identical mid section polygon (which is the higher one in the file). Higher mid section polygon lofted to base of the "trunk" polygon. Two individual profiles formed that are the same as the trunk polygon exterior dimensions but overlapping. The left and right trunk polygons were lofted individually up to the top using the same method of loft from profile to profile and using last profile as start of next loft. everything was then summed with boolean add selected solids in one action. Then I tried filletting.

Hi Murry,

That is an interesting technique. I have been able to fillet that corner in one of the files attached previously. That was a very difficult corner to fillet!

Much of the issues I have been having with filleting at the moment are with the with the horizontal sections of the part that are where the loft profiles are and with the vertical edges that change angle when going from top to bottom of the part.

Hi All,

I updated my version to the recommended build from the link.

I then went all the way back to lofting from each 2D profile.

In doing so I found that this newer build of Turbocad is behaving weird for at least one of the profiles. I have attached the profile here. I have rebuilt the profile a few times and performed an extrude test on it. In the extrude test it does not recognize the profile as a continuous profile. I tried joining this profile and it will not. I inspected all the junctions between the arc and polyline and they are fine.

When trying to loft to or from this profile it gives me an error. I did not have this issue in the previous version that I was using.

Is there a new command that is needed to make this a continuous profile in this version of TC that was not needed previously to extrude or loft the object?

So I have upgraded to TC Plat 2019. It is still a difficult object to put together. I have noticed that multi add does not recognize that these are conjoined solids anymore when they are no ACIS and I must manually explode them before adding or add them together one at a time with boolean add. There are more options for fillet but it seems less edges will fillet.

All of my profiles are still closed however even with more options it is difficult to say which to use and even after trying different options it is still very difficult.

I'm not sure that this completely simplifies down to this statement however I don't know much more complexity about this program than this.

It seems that there is a problem filleting between two loft profiles that have splines in the profile. The fillet appears to get stuck there.

Attached is another example where I cannot fillet the remaining horizontal areas between the lofted profiles. I was able to loft between a polygon and an extruded profile and was able to fillet between them however I was not able to fillet between a lofted profile that had rounded edges because it was intersected and lofted from a solid that had vertical fillets.

It seems that if I could pre-round all the instances of four edges that intersect a the same point it would help this problem dramatically because filleting an edge at a time does not round these type of corners.

I suppose I have to place a sphere at every intersection that cannot be filleted?

If I am going to and from the same loft shouldn't the edges all intersect because they start and end with the same profile edges?

I suppose I have to place a sphere at every intersection that cannot be filleted?

If I am going to and from the same loft shouldn't the edges all intersect because they start and end with the same profile edges?

Hi Dean,
Can you explain a lot  ;D more in detail what to do with the 2d profiles that you posted. I mean, what steps are you taking > step by step  :)
Also, what is the fillet radius 2D or 3D

I'm not sure that this completely simplifies down to this statement however I don't know much more complexity about this program than this.

It seems that there is a problem filleting between two loft profiles that have splines in the profile. The fillet appears to get stuck there.

Attached is another example where I cannot fillet the remaining horizontal areas between the lofted profiles. I was able to loft between a polygon and an extruded profile and was able to fillet between them however I was not able to fillet between a lofted profile that had rounded edges because it was intersected and lofted from a solid that had vertical fillets.

Hi,

Of course I can, it is above but here are the steps again

"Starting from the bottom of the file. Circle lofted to closed polygon. Same closed polygon profile lofted to midsection polygon. Same mid section polygon lofted to identical mid section polygon (which is the higher one in the file). Higher mid section polygon lofted to base of the "trunk" polygon. Two individual profiles formed that are the same as the trunk polygon exterior dimensions but overlapping. The left and right trunk polygons were lofted individually up to the top using the same method of loft from profile to profile and using last profile as start of next loft. everything was then summed with boolean add selected solids in one action. Then I tried filletting."

In summary:
There are several files attached in this forum post. Some of which are just the 2D profiles and some are the 3D objects resulting from the 2D profiles. I am having the most difficult time applying a 0.040" fillet or even a 0.020" fillet to all edges and especially having trouble applying fillets where 4 edges meet as a single point.

This solid is the outside of another object that sits inside and for that reason I must maintain precise control on the size of the object. I cannot simply do a smooth continuous loft I have to do the lofts individually and each part must meet with an edge and a fillet must be applied to each edge.

Does that help?

Today I have been trying to investigate alternate methods to construct this object including sweeping a semi-circle that is set back and using that in an additive or subtractive way. This is incredibly difficult to do because of the irregularity of the solid!

I have minimized twist checked in my lofting shape properties. But in some instances the object twisted anyways. It was not that bad when I loft from Polygon to circle however when I loft from circle to polygon it can twist and it twists even with the minimized twist box checked.

What would result in the cleanest addition? Box checked or not?

Using Prism instead of loft for some of the solids did not help with filleting.

It is also very difficult to extrude and draft angle geometric objects to add them together to reproduce the shape. I don't think this object can be created any other way. If I cannot fillet a loft it can't work.

The object base cannot be created using 6 guide lines.

Using the most recent drawing you posted > "Object extrusion and lofting issue(2)"
I copied then lofted with use compound profile then fillet at .02.
> Are you using compound profile when you Loft?

Yes I realized that when I installed turbocad 2019 there were a number of settings that aren't checked by default. Compound profile was one of them. This solid part problem was resolved. Still having issues with filleting the object.

I have tried
1.) Using lofts
2.) Using Prisms
3.) Using a basic Extrude for the center long piece
4.) Using different fillet types (this could cause additional tooling problems and expense for the design to be made later on)
5.) Open profiles and closed profiles behave the same when I try to fillet (between TC21 and TC2019) however it seems that there are less problem points with closing all profiles.
6.) The most difficult part seems to be the areas where four edges collide at a point.
7.) Filleting together three surfaces using the new tool did not help
8.) Lofting with guide lines did not help
9.) I checked each loft individually to make sure that there weren't any strange edges on the joining surfaces with the slice tool. None were found.
10.) I am either having issues with horizontal or vertical fillets on the model it seems that when I do one the other becomes not filletable.
11.) I still have questions about the loft minimize twist check box
12.)I tried lofting rounded profiles and ended up with horizontal fillet issues because the fillet tool was stopping at sweeps
13.) I tried exploding a profile created by an intersection.
14.) I tried using spheres and sweeps to recreate the object in a different way. I was having a very difficult time reproducing the geometry.
15.) I tried filleting as summed solids as well as an ACIS object, no improvements

Today I will be trying to sweep bandages around the edges and subtracting the edge to make it rounder to see if that helps. I would rather not have to go through this on a complicated object.
