Model Creation Help
There is a type of shape I have to draw often. I consider it very simple but it always becomes very completed in Inventor. My current project is a Fluted Tucsan Column which I will mill on my CNC Router. The bottom third of the column is straight then taper down. The taper is not straight but is a curve defined centuries ago. I also do odd shaped domes which are similar in that there XY cross section only changes in scale. I will try and give a simple example of the type of shape I am trying to create.
Draw on 2x2 square centered on 0,0,0 on the XY plan
Draw a 1x1 square centered on 0,0,2 parallel
Draw a 2 radius arc on the YZ plan from 0,1,0 to 0,.5,2
Now what I want is a loft along the Z axis between the (2) squares with the radius controlling the size of the intermediate XY plane cross sections. IE if the squares where circles the shape I want could be created by revolving the 2 radius around Z.
A while back I did a dome for Las Vegas. I had to draw over 100 ellipses and loft thru them to get the correct shape. It should have been simple.
Any suggestion would be appreciated
