Example we van take a motor assembly which contains some internal components. In between motor's outer case & internal components there is some vaccum. From this input I need out put as a single body which is not supposed to have any internal vaccum space. It should be a single complete solid.
We can take any solid edge training material samples as test case.
You have to do this almost manually in Solid Edge.
Here is a video:
Unfortunately I don't know better way to do this (we have no srink wrap or defeature command).
Another method I use is to model over the components in another part file.
Sync ASM modeling in context does a great job of this.
1) Create a new ASM
2) Place the Sub-ASM in it.
3) Create in Place a new part that is grounded
4) Create the new part using Sync modeling operations by selecting faces from other components to extrude etc. (Usually you do not have to draw any sketches at all.)
NOTE: Sync extrude can use all edges, interior edges or exterior edges of a face to make the cut/protrusion. It can als use edges from other parts. Try the options and see.
5) If needed you can also use sync Boolean commands to union, subtract precise components to the model. Such as connectors etc. (Break the link as needed)
EX: Create a cylinder and then boolean you outer part to it.
I use this method all the time to model parts in ASM. It generally cuts out the entire sketch step and is a real time saver.
Hope this helps
PS. The ST7 Sync Box and Cylinder commands work nicely for this as well.
