Extend an Arc?

Hi All,

 

I'd like to express my appreciation for all the help I've gotten on this forum since I started this journey of converting existing VBA code into VB.NET.

 

I am almost done with my project, but I just encountered another problem, which has me really stumped...

 

I have an arc and a line, and I'd like to extend the endpoint of the arc so that it meets the startpoint of the line (image attached in this post). I've tried every which way I could think of, and the results are never what I wish to accomplish.

 

I searched this forum, and found a likely solution where the CircularArc3D object is being utilized, but unfortunately, this solution utilizes the Curve object's IntersectWith method, and this method crashes my code on a 32-bit system running AutoCAD 2010.

 

In my code, I also tried arc.EndPoint=line.StartPoint but when I execute, I get a NotImplementedException error in AutoCAD 2010.

 

Any pointers or suggestions?

 

Many thanks in advance...

Thanks for the reply. But I've already been through that post before, and realized it wouldn't solve my problems; I'm not using command line to do my fillet.

 

However, you just gave me an insight as to what I can try; I can see if filleting will solve this problem. Lemme give it a try...

Problem solved. I tried fillet, and it created the necessary arc to replace the one I needed to extend.

 

Thanks for the fillet insight...
