3d slicing with surface
Read 519 times
August 05, 2017, 04:15:20 AM
Hello,
is there a possibility to 3d slice an 3d object with a geometrical shape such is a rectangle?

I know there is a Slice by surface option in 3d slice tool but I can't figure out how to make surface out of 2d object.

For instance, I have 2 circles that have some depth (are extruded). I would like to slice part of the extruded object by the edges of the placed rectangle (I could use slice by 2d line twice, but when I do that extruded object changes angle and is messed up).

Any ideas?

Have you try'd Options/ Acis>> Expert Faceter parameters and change Normal Tolerances from 15 to 1.

PS, if you go in to your profile and set what version of TC you use in the signature field there, it help people to help you ;)

Hi, I've changed that parameter but what is accomplished by that?

Thanks, now people know :)

If your objects are "Solid" it will become "Acis Solid" after the slicing and you should be able to see the difference i believe.

You can turn a closed polyline into a surface. Select it. then go to format, surface from profile.
You can also extrude an open polyline which would give you a surface to use as the slicing profile.

Remember when you use slice by line that camera view effects the direction that it is sliced, because it slices perpendicular to the view.
- I think that is why you are having issues with the angles changing.

The other method - which I like using is slice by work plane. Make the top of your box the current work plane using work plane by facet.
and change to slice by workplane.

It seems that turning on this parameter decreases system performance by a huge margine (object is now sliced better, but I must wait for a minute or two instead of a second for a scene to compute).

I don't have Surface from profile command in the Format menu (nor in the all commands list).

Second problem is that I can't extrude open polyline. EDIT solved that by un-selecting compound profile when extruding

Slice by plane works though, but what would be very good thing is ability to slice by polyline.

If you look for the command under all commands its "from profile"

Take a look at the Slice by 'Surface' topic back in 2014.

 Unchecking compound profile breaks association with the extrusion, it can't be edited afterwards, so the slice profile can't be changed without undoing to before the extrusion.  That capacity is like a feature in the part tree that can be reordered without having to be accessed through the part tree, dismissing it is poor practice that doesn't take advantage of a powerful feature.  It turns a part into a dumb object at that point.  There's another option alongside compound profile, 'finish selection of profile', which enables extrusion of an open compound profile - alt + x are the hot keys to finish selection.

I have a similar problem which I will introduce here. I generate boat hulls by lofting cross sections.  To get a sole(floor) profile the obvious action is to slice it at the appropriate height. But, it wont slice  :( I am using 'slice by work plane' which works well for other items

What to do?

Thanks

If the object to be sliced is a Loft or an ACIS Solid or a TC Surface, it should slice OK. If the Part Tree is enabled and the object is reported in the Selection Info palette as a "Part," try exploding it one time. If the object is a Group or a Block, or if it has been exploded into a bunch of Polylines, then it cannot be sliced.
