Are they structured blocks? If so, they're likely unbalanced.

Undefined structured blocks mean that somehow they were created as IxJxK blocks but something happened (for example, putting more points on curve) that threw off the IxJxK balance. You should inspect the connectors on the edges of your blocks to ensure all the i-directed connectors have the same number of points, the j-directed connectors have the same number, etc.

Hope this helps.

Hi,
I have the same question with an extruded prisms (unstructured) block. When I change the dimension of connectors, the prism block becomes "undefined". Is the only way to re-extrude the block based on the new surface domain, or is there another solution?

Thank you!

Jérémie

Hello Jeremie84:

If you extruded prisms using the traditional/classic methods - Create, Block, Extrude, Normal - the resulting blocks are fragile and an action like redimensioning one of its edges will empty the resulting block (i.e. make its interior undefined) because the code doesn't have a way of blending that change onto the interior.

You have to restart the extrusion using Re-Extrude.
