Boolean Operations

3-D Standard > Process > Add

If any problems occur with Boolean operations, you should bear the following in mind:

Example: You want to union two parts which are not in contact with each other. It then frequently makes sense to lengthen both parts so that they intersect. It is then easier for the CAD program to union the two parts. The intersection is deleted again during union.
In the feature log, change the sequence of processing steps that took place before the Boolean operation. Then, perform the Boolean operations again by means of a feature recalculation.
If you union more than two parts, first union the parts that are in contact with or intersect with each other with their entire surfaces. Union the parts only the lines of which are in contact with each other (i.e. not their surfaces) last.
In very rare cases, the component is drawn many millions of mm away from the absolute origin. This leads to the "consumption" of a large number of integer places during internal saving of the absolute coordinates. Fewer significant decimal places are available as a result. In this case, you should move the component nearer to the absolute origin. However, this is only necessary if a component is extremely far away from the absolute origin.

Tip: Before using Information, 3-D point coordinates to determine the absolute coordinates of the part you need to delete all processing planes, as the coordinates in respect of the active processing plane will otherwise be displayed, instead of those in respect of the absolute origin of the world coordinate system.
