Fix Parts In Assembly

Gilad

Hi

I got imported stp file of a bearing.
when it's translate to part studio, i get 11 different parts. they are not connected, but they float in the air.
I tried to put them in assembly and fix all the parts, and then us it as one part.
but when i put assembly with fix parts in a new assembly, all fix parts are moving free without relation to each other, and not as one part.
How can i fix the bearing, that it will behave as one part ?

Thanls Gilad

Use the group feature.  When instances are grouped, they will not move relative to one another based on the positioning they were in when grouped.

Or if you wan't it to be just 1 part, use boolean.

To do this, select parts from part list, RMB click for menu - select boolean. It should open boolean dialog with the parts already in list and Union is default - this will combine multiple parts into one part.

I suggest you can use group relationship to fix some parts. For example,when creating a ball bearing assembly, you can use group feature for all balls,so all balls can be moved together ,then give some constraints  among inner ring,outer ring and ball group.

Just a clarification of @3dcad 's excellent suggestion,  for those unfamiliar with Boolean Union to turn multiple solids into one solid body: it works only for parts which form a valid single solid, meaning one with no zero thickness geometry (eg if adjacent parts are only touching, they must touch along a face, not an edge or a point).

An example of a not-so-obvious consequence of this: if a ball bearing is modelled with the balls exactly coradial with the raceways, the balls will touch the raceways only along a single line, and a Union will not unite them.
