Issue with union of solids
Hi All,
I'm having a few issues to make a union of some 3D solids. I've had 2 errors so far (84003 and 84015).
I have 3 solids. 2 of the solids were extruded and had an curve subtracted. The 3rd solid was lofted from polylines and converted into a 3D solid. In Qselect, all objects are solids, but union does not work with Autocad telling me that the Boolean operation cannot associate surfaces to solids. I've attached the drawing. Can anyone help please and tell me how to fix this. This has been bothering me for some time now and I'm starting to lose my hair ;o)
Thanks in advance,
Chris

There are gaps between the solids the Acad cannot deal with apparently. Sliced at height of 20. gap is obvious.

Thanks a lot Dave,
I thought I checked all gaps ;o)
I extended the extrusions inward to cover the gaps but that gave me a related error (this time error 84028 for overlapping solids). But it seems a work-around is to slice all solids at regular intervals, then union the solids of each slice, and then union the unioned slices. Worked like a charm!
Thanks again, I can already feel my hair growing back ;o)

The cheat on this example is actually very easy. copy the solids to the left and right one at a time with the lower outer corner as base point and paste e towards the central object along the bottom edges just a hair more than the gap widest width. That covers the gaps and as best as I can tell doesn't change the overall final object. The 5 solids union perfectly well after that.
