Civil Geometry crash sequence

Neil,

As you suspected:

Because of the way Civil Geometry is "ruled" at creation only the landing point will remain tangent. The arc begin point and tangent bearing is ruled when it is locked in from the paste routine.

Another solution and not: The Arc between Elements tools is sucessful if the angle between elements is acute, less than 90 degrees. If it is more it defaults to a clockwise angle. When sucessful the ARC will allow both tangent bearings to vary .

Does the workaround result in an arc that stays tangent when the tangents move?

I replicated the issue, I am working on it, please I recommended for now to use Arc to Element tool (copy the bearing from the first element), then select the second element(Tangent), set offset zero, check on End Tangent method, paste the bearing from first element, press Enter, then snap of the begin of arc, then select the other element to trim, basically is like Vern Danforth show in his comment.

Mike ,

I was able to re-create the problem you have reported, yes. ... try this as a work around!

1. Use the select tool to highlight the tangent bearing angle of the first element you want to begin the arc.Copy the angle using, CNTL C

2. Use Civil Tools >Horizontal Geometry >Arc to Element tool

a. Select the element tangent line to LAND on

b. set or lock the offset to zero

c. Toggle to the End Tangent Method

d. Paste the angle from step 2 CNTR V , enter to lock

e. snap to the BEGIN point of the ARC

f. Trim back
