Rotate_Extrude Problem

Recommended Posts

I am trying to follow the Extruding a Polygon example in the OpenSCAD User Manual. I am getting a Preview result as shown in the attached photo. The Preview seems to have inherited the nominal 1 unit thickness of the polygon shape. When I progress to the Render function I get the following warnings:

Rendering Polygon Mesh using CGAL...

WARNING: Mixing 2D and 3D objects is not supported.

WARNING: Ignoring 3D child object for 2D operation

At the conclusion of the Render process the graphic displays just a 1 Dimensional red line on the x-axis.

Any idea what I am doing wrong here?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
