Boolean Operation Real Usage in CATIA?
Boolean Operation Real Usage in CATIA?
(OP)
Hi All,
This is my first message on this forum. I am an expert user of Pro/Engineer But recently we have shifted ourselves from Pro/E to CATIA V5R16. So I am very kind of new to CATIA V5.
I have a question which I will be obliged if some of you could answer. What exactly is the purpose of Boolean Operation in CATIA V5. As I dont see it helps much in making shapes which are not possible to make through parametric modeling. There is one valid point about Boolean Features that its fast in regeneration/update. Besides this point can someone elaborate me on their real usage. There are many shapes that can be modeled with or without Boolean Operation so my question would be when to use Boolean Operation and when not to? OR is it just an old obsolete tool which DS is keeping it along just to leverage the old users of CATIA??
I will really appreaciate anyone's remarks on the above mentioned issue.
Regards

RE: Boolean Operation Real Usage in CATIA?
Compared to CATIA V4 (where every feature had to be booleaned into the solid), V5 booleans are no longer neccessary.
But, like Derek said, the ability to organize the part model into multiple partbodies is valuable, and booleans can then be used to "assemble" the partbodies.
Where I work, we design many molded parts and we use a core/cavity method. A big block of material goes into the first partbody; the cavity side is boolean removed; and the core side is boolean removed. Machining operations are in another partbody that is also boolean removed.
I also like to use individual partbodies when I do patterns of features using the 'current solid' option. Again these bodies are boolean assembled into the higher level partbody.
RE: Boolean Operation Real Usage in CATIA?
Imagine this particular situation: In Pro sometimes you cannot create a readius into a small cavity because there is not enough material. To solve the problem, you will make a colosed surface, round edges and then you cut the solid with this surface.
Same thing cam be done in CATIA but using solids in diffrent bodies.

If you create the pattern on a separate body, then boolean it into the main body, it helps cut down on the rebuild time, I think. (See the catia online help docs on this one...)
RE: Boolean Operation Real Usage in CATIA?
Classic example - operations that require shell, draft, and fillet, all in one part.
I had a casting that needed to be made with molded pockets in the "legs", which were joined to a cylindrical part. The best way to make them was to make the "legs" first, in their own part body, shell them, and then join them before putting radii on the whole thing.
In this case, due to the logic of creating the objects, it was not possible, in any even, to create the part without booleans.
If you do enough of this, for a long enough time, you will certainly find a need for Booleans.
