    Default 3D solid

    I need to make a solid spiral column much like a spring. So how do you sweep a rectangle or circle along a curve such as a spiral curve. The result needs to be a solid.

    That only seems to produce a hollow tube, probably me but I couldn`t find a way to do it in BC and get a proper solid, I did manage it in Fusion 360 though, only took less than a minute each to produce the spirals shown in the attached images, the solids are .STEP files in the attached Zip file, enjoy

    Well, probably right, however they are referred to as a "spiral" in some CAD softwares "Potato-PotAto", Tomato-TomAto" ?????

    That is Felix here (Cat food adverts)

    Helix was a cartoon cat and I believe also a character in the Asterisk stories

    This is all nicely off topic

    Thanks for the response. I know I can sweep a shape along a curve in Pro-E but I was trying to do it in BobCad 30. A Helix would be okay too. The spiral shape in Other can be used to sweep a surface but can the user make a solid from a surface? I was trying to make spiral column. The stretch corner doesn't seem to work with solids, otherwise one could distort a square beam. Also I inserted an STL column but I could not boolean a shape either subtract or add. This is a very powerful program and I am continually impressed with what it can do but maybe this is a current limitation
