Trimming a surface
Trimming a surface
(OP)
I was sent a number of *.stp files I needed for a design. One imported as "surface bodies". The problem is I have to modify the part by cutting part of it off.
I tried the surface trim tool and it always cuts away exactly the part. No mater what I try its always exactly wrong. For example:
1. I make a sketch of a rectangle surrounding the section of the part I want to cut away. Start the trim tool. Select the sketch. Viola... everything outside the rectangle disappears.
2. Fine, A change in tactics... I make a sketch of a rectangle surrounding the section of the part I want to keep this time. Start the trim tool. Select the sketch. Viola... everything inside the rectangle disappears.
What in the world am I doing wrong?

Also, the rest of the part disappearing happens before I select any "pieces to keep" or remove.

You can extrude the side sketch and use the extrude as a trim tool or mutually trim.
RE: Trimming a surface
Have you tried healing the geometry so it stitches into a solid (assuming the surfaces form a closed volume)?
Import the STEP to a new file. Without adding any more features, right-click any surface in the feature manager tree and select "Diagnosis". From the diagnosis tool, you can fix faces and close gaps. If the gaps all close, SW gives you a solid.
Diagnosis and repair has improved significantly in SW 2004 & 2005 (from 2003). One of the few things that got more useful.
