Creating a longitudinal circular hole

      Hello,

      I am trying to create a hole along the height of a concrete column with square cross section. I tried to use part trim option using curve line but it is only executable for shell element. Is there a way to delete solid elements and create circular shaft type hole in the column?

      Thanks

      Hi

      I would create 4 edges for square, one hole in it (centre) create a face from them (surface tool : FillPin using these 5 edges).

      Surface mesh face created.

      Finally use Element generation tool to extrude into HEX elements along the length of column. 

       

       

      All the best

       

      Erik

      Hi, 

      Please try to use DEFINE_CURVE_TRIM_3D with DEPTH pram. 

      Cheers, Ram

      Thank you Erko for your reply, I could not implement exactly your solution but I got an idea from it. So I used trim option on 4n shell part and then created solid of it using solid-face-drag option.

      Thank you Ram for your reply. I will try and see how it goes.
