Error code number 18015

Hi,

I never experience this issue before as I was trying to solid union the square beam and the message appeared below  'UNION
Select objects: 1 found
Select objects: 1 found, 2 total
Select objects: Specify opposite corner: 1 found, 3 total
Select objects:
The Boolean operation on solid and/or surface bodies failed.
Modeling Operation Error:
Error Code Number is 18015

So I tried to copy the cross beam like this 'X' in different locations and created a new beam and then it worked which is very odd. Originally I created the square beam by creating the square as a Region and then Extrude it to the long length. Any advice would be much appreciated! Thanks

If you open this drawing with older autocad versions it would say can't union because noncoplanar

with newer versions it said error code ...blah, blah....... and doesn't tell you why.

No, I created a new drawing file and copy the old 2D drawing from the old version in the new drawing and use them as a guide and created the 3D model in the new drawing.  Thanks

Now I have the new code number below.

The Boolean operation on solid and/or surface bodies failed.
Modeling Operation Error:
Error Code Number is 18028

Please advise. Thanks

for some reason in the process of creating the solid one or more planes without thickness have been formed that prevent them from joining you have to find a way to eliminate them or give them some kind of thickness in order to join the solid to another
