Solids not Intersecting

Trying to Trim the face of a bridge abutment but can’t get it to work. Did the same on the other side of the bridge and it worked fine. Just can’t get it to work on this one. Need to subtract the Green block from the Red solid. Would be great to know why this is not working. this happens on the odd one from time to time.

This is what you want?

I used Trim from Bool Tools 2 instead of the native Solid Tools.

Digging a little I see you’ve scaled the groups without first opening the groups for editing. It may be that has something to do with the Solid Tools failing. You could explode each group and remake it to ensure the scale is correct and then try trimming the one with the other.

thanks Dave

Didn’t know about exploding groups before scaling. Tried that and it’s worked.

much appreciated

thanks

That’s not what I was suggesting but as long as you were able to get the job done
