Remove (Boolean) one part from another..Basic Operation
Remove (Boolean) one part from another..Basic Operation
(OP)
Good Day,
This is my first post and I am a somewhat of a novice to Catia. I work with a lot of Catia, Step files that have been given to me by our customers. Most of the time they come in as CATParts in V5. I need to remove an area of the part from a block, which I create in order to provide a nest for the original part to set into. I then send that newly created part to our machine guy and he makes it from my data. The problem is that everytime Catia comes up with an error. The Help is almost worthless in solving this. I would appreciate any words of wisdom.
Thanks.......Dezineguy

RE: Remove (Boolean) one part from another..Basic Operation
Are you working in a single Part? Or in a Product with multiple Parts? When you import the STEP file, how do you get that geometry into the part with the block? Did the STEP file create Solid geometry (BODY) or surfaces (Geometric Sets)? What is the error message you are getting?
RE: Remove (Boolean) one part from another..Basic Operation
I knew that there would be some questions. The .step part was converted to a CATPart and I ended up with a geometrical set. I selected a face on the part (single part) and then invoked the sketcher icon. I then drew a rectangle and exited sketcher, extruded as body. After selecting the "remove" the Remove window came up. I wanted the original part to subtract a complicated area from the cube I just drew in, but when I attempt to select the original part I only get a solid circle indicator with a minus sign in it where my cursor is. If I select the part I just drew, I get the message "Part Body cannot be used to perform the boolean operation. Please select another body." If the problem is that the geometrical set will not allow this, how do I turn it into a Part Body?
I would like to perform this, and other types of boolean commands whether it is a CATProduct with multiple parts or CATPart.
I know these may be basic questions, excuse my lack of knowledge.

RE: Remove (Boolean) one part from another..Basic Operation
you are building solid geometry (pad) in the main part body, and then try to substract it from surfaces (in the geometrical set). This will not work.
First you need to turn your surfaces (from geometrical set) to a solid (in the partbody). you can do this with "close surface" in PartDesign.
Then you have 2 options :
1)make a sketch in the same body and make a pocket
2)make a new body (insert / body), then make the sketch, a pad (or pocket) then boolean operation.
this might help you to perform your job but i strongly suggest an action on my first line.
Have fun
