Unable to put any more holes in solid.
AerospaceDesk posted a topic in AutoCAD 3D Modelling & Rendering
Here I have a flanged Alclad Plate I developed in AutoCAD2015 Trial, I since ran it through CorelCAD 2015 because I ran out of trial time. I have to sort it out to get more time. The problem is that I tried to put a third flange on the plate (a 90 deg one) after I had successfully extruded all the holes you can see. The 3rd flange was created by extruding concentric cylinders and subtracting a rectangular block from that. I found out I was having trouble when I tried to put a relief hole in the corner where the end of the 3rd flange meets the plate at a perpendicular intersection. That did not work; but sheetmetal workers do this before they bend the metal. I found that in the 2D views, the third flange separates form the plate. In the 3D model space, AutoCAD and CorelCAD both report the "assembly" as a 3D Solid. I would like to learn what is causing this to happen; stopping me making more holes.. Thank you for your help.
