First, instead of turning the second control point 180° it is better to change properties of this control point from clockwise to counter clockwise. This avoids the squishing effect you have. Then to avoid the overlap at crossing, you need to add two bezier control points and place/orient them as needed. Here is an example:

You have to keep an eye on order of control points. Use the source window for this !

i did play little longer , what i have to say about ldcad, its by far the more flexible and complete Lego CAD software.

its not the most easy to learn but has the most advance features out there.

the only missing things that i had in mind the developer already has in his pipe line.

congratulations

New path points are always added after the current selected one if possible.

Thanks, I've always targeted LDCad at the more advanced / larger model creating crowd.
