here's a screenie:

but, as u can see, the block isn?t totally solid..only the rectangular cubes are what do I need to do to make it just one block? (for the columns, I used the already made solids that bobcad-cam offers)

Solids are planar surfaces that have been stitched together.

1, select the lines that form a square or a rectangle. The arrow direction on each line must be head to tail.

2, execute the SOLIDS/SURFACE CREATION/PLANAR SURFACE command with the distance = 0.

3, repeat steps 1 and 2 until all the surfaces have been created.

4, select all the surfaces and execute the SOLIDS/STITCHING/STICH SURFACES TO SOLID.

thx so much!
