Split body with another body and keep parts

[kaiathome]

Hello,

I have 2 3D-bodys. Body A is big and flat. Body B goes straigth trough and crosses body A. Now I want, that body A is splitting body B into 2 parts. All parts should be present.

I have AutoCAD 2019

Many thanks in advance

Hallo,

ich habe 2 3D-Volumenkörper. Körper A ist groß und flach. Körper B geht durch den Körper A. Ich möchte, dass Körper A den Körper B in 2 Teile teilt. Alle Teile sollen erhalten bleiben.

Ich habe AutoCAD 2019.

Vielen Dank für Hinweise im Voraus.

Show a snap photo, sounds like a body of an airplane ☺

You are very close with your idea! 🙂 Should look like the other side! But don't know, how i made it! I tried everything.

[Patchy]

If they are both 3d solid try subtract command and choose keep both, or maybe slice command.

Like this?

 

[kaiathome]

I already tried. AutoCAD is not asking me to keep it and I dont see any options to choose. I dont have Fusion, I think it asks.

What is slice command? I have the german version. I did not see "schneiden" (slice/cut).

[Patchy]

I'm not using Fusion, only Autocad.

Attach your .dwg in 2007 format, let's see which command will work for your drawing.

[kaiathome]

Ok. But I need commands for AutoCAD, not für Fusion.

[Patchy]

Sorry, I meant I don't use Fusion.

Make 2 surfaces by using LOFT comand on red and green arc then and use command SLICE, or .Slice or -Slice (see which one works)

and use Surface for slicing.

Thank you very much. I used "In Fläche konvertieren" under "Netz". In english: "Convert to surface" under "grid".

But I just used "in Fläche kovertieren" once. Then "Kappen" (don't know the english word, its like shorten) and in options "surface". Then you get 2 new objects. You can convert the surface to a body again, i did it, but i don't know, if its necessary for 3D-printing.

There must be a shorter way, perhaps you can follow this link:

and ask

 He knows the command for SLICE.

If you are looking to make only the inside portion of the box here's another way.

1. Create a copy of the tube.
2. Subtract the tube from the box (this will consume one of the tube copies).  Hide the tube so you can see the resut and explode it.
   
3.  Delete the surfaces you do not want such that you have enough surfaces to define a watertight volume.
   
4. Use the surfsculpt command to make a 3D solid from the surfaces.
   
5. Union this with the tube.

Hello lee.minardi,

your solution sounds good and well described. But with this I have the problem, that copying an object on the same place with "paste with original coordinates" is inaktive. So I tried the tool copy (icon with the 3 circles), select move, enter "0" and its working. So your solution is working and fine. Thank you very much.

A nice christmas for all!
