Determining "not" interferance
Determining "not" interferance
(OP)
We understand the concept and usefulness of finding interferences in assemblies.
To take that in another direction; how would one find out if there is "not" interference; specifically between holes or voids.
For instance, in mold design it is necessary to make sure water lines, ejector pin holes, fastener holes and part cavities do not interfere.....or, in other words break into each other.
Is there a way to do this without resorting to scrutinizing each and every section in question in the completed mold assembly?
Very often this has to be done in multiple directions and can be very time-consuming.
Thanks

You need to know the tolerances.

RE: Determining "not" interferance
- Make a new part and insert the current part as the first feature.
- Create plugs to close in all of the holes / cavities (make all negative spaces into voids).
- Make yet another part that is a block large enough to hold the plugged part.
- Insert the plugged part into the new part so that it is entirely within the new part.
- Combine the two solid bodies, subtracting the plugged part from the block. This should result in several solid bodies.
- Hide the outside body and you should be able to see all of the previously negative spaces as positive ones. If the negative spaces have intersected their positive representations will be part of the same solid body.
