I tried to create a fairly straightforward 3D symbol, of a gallow bracket, which would be used to support a small entrance porch roof, over a front entrance.
3D image lookes like the image below, GB1 Rendered. It seems correct to me:
Yet, when looked in elevation, additional lines are visible within the gallow bracket.
First I created this symbol within Softplan, using Softplan tools only.
Secondly I created this symbol within Autocad.
Both designs create these additional lines.
Does anybody know the cause of this, and is aware of a 'work-around' to eliminate these additional lines?
