I’m trying to generate a dish-like surface but am getting some strange results - I’d be grateful for any suggestions to resolve.
I have drawn 3 nested profiles in the same plane which are scaled versions of each other. To create the dish I have selected the two outer shapes & the annular surface in between & moved these perpendicular to the plane.
The resulting modified surface between the inner & middle profiles is not a neat minimum area surface - I have attached a file to illustrate:
- In orientation A the faces parallel to the green axis are mis-shapen
- If the task is repeated with the profiles rotated by 90 degrees (B) the problem recurs with the (now different) faces parallel to the green axis
- C has been rotated by 45 degrees & suffers from some different defects though these still seem to be connected with alignment to the green axis
Am I making a simple error or am I using the wrong method to construct this shape?
(I noted that in performing the Move command inferencing did not allow me to pick up any features / points in the direction of the blue axis - I had to use an arrow key to constrain the move.)Dish problem.skp (2.9 MB)
