In need of more help.
I have a model part that was made from an assembly. For some reason I cannot use cut to remove material from some areas of the model.
I have tried revolve cut, extrude cut, revolve cut and hole.
I converted it to a .stp and opened as a .prt and even as a .asm, and still cannot mdify the model.
In the design tree, is there anything that says "design body" or "construction body" If so, which.
Another question.....the original part which you translated.....was it an .stl file?
The original was a .par file that was converted from a .asm file. I do not have access to the original assembly.
What I am trying to do is remove parts that will have made up the assembly. (i.e. cover plate, screws)
It seems that the cover plate I am trying to remove is Ø430. I can cut out Ø429.99, but this leaves an edge that I cannot remove.
sees like you are most likely dealing with a mixture of design and Construction (surface) bodies.
and probably seeing boolean errors.
do you have features in the PF? can you select by feature instead of graphically?
a picture or model upload would help us, help you.
I will try explain. (i did manage to make it work).
On the attached file.
Image 1: I want to cut back from the face with the small bore 26.5mm.
Image 2: The diameter is Ø430mm, same as the model diameter.
Image 3: I changed cut diameter to Ø429.99mm. As you can see I can cut.
Image 4: I changed the diameter to Ø430.001mm. As you can see I can cut.
It seems the issue is i cannot cut using the same diameter as Ø430mm.
Is it that solid edge just cannot do it or am I missing something?
OK, now everything is clear.
This is the typical situation for the old fashioned "Non-Manifold Situation"
At least this is my idea when seeing Your pictures.
If I have the part, man could test it directly.
So at the moment I only assume this.
If You try to cut the 430mm diameter then there will be a tangent to another cylindar situation where volume with a singualarity will be created.
And this is something what Parasolid modeler can not achieve.
By the way also every real part will break at the same place.
So I suppose, that a situation which can't be in reallity will prevent You from creating this hole.
Think about possibility and gibe the answer
Yes, as @hawcad said, you are attempting to make a non-manifold body. This occurs when the area being cut leaves a small area that is infinitely small at that location. There is both material there and no material there, which cannot be. You could turn it into a multi body part, or do like what you did and make sure there's some material left when you cut it.
