Trim with untrimmed surfaces

[rollupswx]

In Autodesk Inventor there is a tool called Sculpt that allows trimming (or filling) of areas without the need to have trimmed and knitted surface (can pick any number of untrimmed surface and workplanes and select to remove or add bounded material).

Is there a way to do this in SolidWorks (refer to attached images).

That was finished part -
here is SWx method I'm using requiring trimmed and knitted surface.

I would be able to Sculpt at this point with untrimmed surface in Inventor to get the desired results.

oops, solid body hidden for clarity in showing surfaces. Should have turned it back on of course.

...and that disk shaped surface is acutally a 3.5° revolved conic.

Make sure the 'Merge tangent faces' box is checked when you extrude/modify your feature.

Basically what AutoDesk did was put in a macro that performed a number of separate actions as one.

I can do this with a Split/Combine and Delete Body in SW.
The usual rules for analytic and algorithmic surfaces/faces apply.

I haven't a clue what this has to do with my question?
Did you post to the wrong thread?

There is no Extrude feature in my geometry?
As indicated by kellnerp - Sculpt does a bunch of steps at once without having to trim the surfaces.
See the attached (roughly equivalent) feature trees.

I was trying to discover if there was a hidden technique in SWx that I wasn't aware of.

Here is another example that would have absolutely nothing to do with Extrude.
I can post some *.sldprt files if you think you have a better technique, but not sure if you can open them since they were created in educational version.

 

[kellnerp]

With either method you have to be careful that the body you are cutting with the surface does not extend past the surface if the surface is algorithmic.

In SW it is a few more steps. But it can be done and it is an expensive operation so is not done a whole lot by most people. SW has been in "feature wars" with Autodesk for a long time, and this has detracted from them spending time on debugging and performance improvement. Does inventor give you any idea of how much time the sculpt feature takes to rebuild?
