Dear Bubba
The main problem is that the
Accuracy setting is set at 2" in your image Capture.JPG. As I indicated in a previous message this default value is wrong for Imperial units. It should be of the order of 0.02". This bug will be fixed in the next release. But, you can change this value (see TestBa.png in the attachment).
Also as I previously explained the Profile shape needs to be carefully managed. In your file the Polyline shape contains Arcs. I have updated your model (in the attachment) as follows:
(a) Copied Polyline(

to a new Layer as Polyline(1)
(b) Remove arcs form Polyline(1) with an accuracy of 0.001
(c) Rotate Polyline(1) by 90 deg about X-axis
(d) Apply Transformations to Polyline(1)
(e) Select Polyline(1)
(f) Launch the Plugin and set the Accuracy to a small value.
The results can then be seen in TestBb.png. I have also included the updated CB model as above.
I will be posting the updated version of the plugin in a few days, I am just waiting to see if I get any more bug reports. As I also explained previously there is another bug that you may see in the results as parts of your Profile shape lie exactly on the X,Y plane - you may see some artifacts in the result - these can be resolved by moving the Profile shape up by 0,.001"
I hope this helps
Geoff
