Hi Everyone,

I'm pretty new to the API still, but I'm working on a macro that builds a sketch and creates a thin extrude based on selections made in a user form.  The sketch is just line segments and tangent arcs, and I have gotten pretty far, but I have one line segment that represents a component that has a .118" thickness, and whenever that combination of line segment to tangent arc arises, the Tangent arc reverses direction and the sketch has problems. 

However, if i enter a larger value for that segment, say 1 inch, instead, everything builds as intended.

Any Ideas?  I've tried the add to DB as well. 

I've attached the .swp file in case anyone feels like taking a look.

The selection in question is the "T2J" component in the horizontal list box.  

Also,

How can I use an API call to dimension the overall arc length?

I can add a radial dimension, but can't seem to figure out how to dimension to overall length of the arc.

That would potentially fix this, I think....

Sorry it's a mess and that I have so many questions! I'm still very new to this.
