Alignment Compound curve with 3 curves

[lvthunder]

I was given an alignment that I need to recreate.  The linework is trash since the entire thing is little segments.  Including the curves.  All I have is the length and curve radius'.  The last curve goes like this.  Tangent-spiral-curve-spiral-curve-spiral-curve-spiral-tangent.  The compound curve command from what I saw only allows two curves and not three.  I tried drew the spiral and then when I tried to do the curve it told me the segment wasn't on the main entity when I selected the spiral.  Can someone please help me?

Hi @lvthunder, for such a combination, and knowing the length of the spirals and the radius and length of the circular curves, I'd recreate that alignment going segment by segment.

Use for circular

For spiral you could use, for instance

I hope this helps. Best regards!

That's what I thought, but when I did it the other day it gave me an error, but I froze the linework under it and it worked.  Thanks for the quick reply.
