If TurboCAD had a Twist tool, analogous to its suite of Bend tools, these things would be considerably easier to draw.

(They really weren't as difficult as one might think. Wanna guess how it's done?)

Henry H

Telekinesis?

Wanna guess how it's done?

Yes, but I have no clue

This is my feeble attempt before conceding
I tried a sweep with a twist and got a lesson in humility...

Then I tried to add the lettering

Can I blame it on the older software?

Alan H.

You're too clever for me, Henry.  Have mercy.

Mmm... How about a Facet Edit with a (Text, Brick Mat and Pos/Neg. Mapping)) Projection?  - Al

Henry, you'l too much, I give up Carroll

Rail Sweep with twist?
Like this?

Obviously extruded through a warp in the time/space continuum.

Rail Sweep with twist?
Like this?

That's really pretty. But can you duplicate any of the objects I posted?

Henry H

This is an interesting challenge
give me 24 hours
I'm sure it has to do with wrapping different textures to the facet editing of separate faces of the twisted rail sweep, but I'm not sure of the wrap method yet, although I have achieved slightly similar results using UV1
If this is interesting because I only discovered the other day that the twisted rail sweep can be facet edited with different textures.

Nope. Here's a v16 .tcw file containing only the "Twisted Lattice," stripped of material assignment. Examine it closely and you may spot some clues to its genesis.

I once had a retired brickie do me a retaining wall in the garden, wasn't too different from your pic so I had to tear it down...

I'd say the bend tool with an inclined surface line is in action here, though I'm unable to replicate your images. The lattice would have had a square rod added/bent/exploded/removed.

did I get the pebble?

 Looks like the lettering is following the bend with a small lip, which meens to me it has been written on the surface using flexible text, then subtracted so its actually "CARVED" on the surface and bends when the object is twisted.

 I dont know if this is correct, but I like flexible text and I just found it a few weeks ago.

That produces a curl, rather than a twist. No pebble :-(

I got it.....

"Just master turbocad".  Then it will work

That's kinda the point of this whole exercise: How does one twist an existing object? Or, failing that (and I always fail, never having found a TWIST tool in TCad), how does one fake it?

Henry H

... how does one fake it?

Henry H

tada....

I think Henry taught me this a long time ago when trying to make rope

how does one fake it?

Henry H

Do I get a fake stone

Alan H.

is this correctly done?


althougt i don't know how to change color of object or get text on it


awesome job on the Twisted Lattice, herny.

the screw is easy to do, but the Twisted Lattice is a ridle to me, since i can't open the file

Looks like you've been playing with the Twisted Extrude tool. Lotsa fun, that. Putting text on it is the really tricky part, involving additional tools and putting them to non-standard uses.

To change (or display) a material (and thus a color): Double-click the finished object to open its Properties dialog; go to the "3D" page of the dialog (this is the gateway to the Material Editor); open the "Category" drop-down list and pick one that looks interesting (try "Metals"); open the "Material" list and pick one you think you'll like (try "Polished gold"); click OK to close the dialog. Then render in a Quality mode.

EDIT: P.S. Here's a version of the twisted lattice that you can open in v15 Pro...

It's only a short step, Julian, to the next level: an asymmetrical "insert"

Henry H

Yip, the possibilities are endless, Henry. Is that last one just a simple 3D intersect?

no, i designed a shape with poly line.

than i clicked the copy tool,
added 2 mm on the z axis, enter and again enter to close the popup sign.

..
.
a total of 50 times.

than i devided 360º / 50 = 7,2º.
than i saved 7,2 in the calc memory.

than i rotated each shape 7,2 + 7,2 for the next and so on till i got 360.

than i used the lofting tool to create that shape.
the lofting tool alonse toke me about 30 minutes, than previous was done in 10 min.
but lofting the whole was tricky and lots of warning popup.
than i used the losting tool 3 times to create the screw.

than i copy 1 on each part the basic shape and lofted 2 straight parts.

: )


but i should have added 2 extra shape with a 3,6º rotation to get a better intro.

Wow. That's an impressive application of the lofting tool.

Henry H

Henry:
     You must have an easier way ... please enlighten us.

EDIT: 2nd image; same method ... elaborated.

Don Ritchie

Wow. That's an impressive application of the lofting tool.

Henry H

what you wanna tell me?

did i do it the hard way?

while i read this tread, it give me an idea and i tried, it worked, althoug without text.

i think it's not bad for a guy that today uses Turbocad for precisly a week
 

Henry:
     You must have an easier way ... please enlighten us.

Don Ritchie

i think i know how it's done.

you make a twist, than add 3d letters and substract them, 1 by 1 and later move the letter frames in a other layer and hide.
than make a second twist sligthly smaller and put it inside.

i think that can be done and create the same effect.

In a nutshell...you'll need Twisted Extrude tool (I believe from V16+Mech pack) and use Revolve tool on any shape or text (exploded), make sure any revolved object is on the same centre line as the twisted object. Use 3D subtract or intersect for various results. The final object can then be bent by employing other secret methods.....

Exactly. Alternatively, use Sweep or Rail Sweep in lieu of Twisted Extrude, and apply a nonzero Twist angle. The advantage of Twisted Extrude is that the ends can be "faired" into a flat by specifying  G1 or G2 Continuity.

That'll work. Now how would you do the "Twisted Brick" shown in my first post?

no, i don't

i secondlife you could select each of the faces and add a texture to it.
than fidle so long till you get it aprox matching

sofar i dind't get a chance to use either Sweep or Rail Sweep

Julian Thomas said:

...... use Revolve tool on any shape or text (exploded).....   

Thanks, Julian; that's a lot faster, and gives cleaner edges, than my method which involved rotating individual flexible text characters w/thickness. Never thought of the multiple explodes and revolving.

I must learn to ignore these 'teases' by Henry.

Don Ritchie

Yip, the possibilities are endless, Henry. Is that last one just a simple 3D intersect?

Not quite. I Revolved the green profiles (see attached screenshot) about the horizontal line and intersected the result with a twisted object. Since the profiles don't quite touch the revolution axis, exploding the intersect yielded 16 separate Solids. I deleted those which lay on one particular side of the twisted object. Repeated the procedure with the yellow profiles, this time deleting the Solids on the other side of the twisted object.

Ran into a problem, though: The letter "A," whose sides are oblique to the revolution axis, turned out to be very messy in the vicinity of the axis. A partial cure was to make the twisted object using a single line as a profile; and consequently its intersection with each revolved object was a zero-thickness sheet object. After exploding and throwing away the unwanted pieces, I Shelled the others to impart a nonzero thickness. The resulting pieces looked clean but I was unable to "Fillet" the edges of some of them.
