Resequence Block Links

Top  Previous  Next

When importing models from other CAD programs, it is important to provide Map3D with some way of identifying how blocks are formed.

The best way is simply to adjacent blocks different colour numbers, then Map3D can easily determine which surfaces belong to each block.

Alternatively you can specify a unique block name for each surface.

In cases where this is not possible, a new routine is now available that attempts to determine which surface belong to adjacent blocks.

This is done by searching for surface connections at common corners with the assumption that surfaces are provided in some sort of consistent sequence.

For example, surfaces 1-12 all form a block, surface 13-24 form another blocks etc.

The new "CAD > Resequence Block Links" routine executes this processing.

Note that this routine should only be used as a last resort to unscramble improperly constructed models.
