Hi there:
I am receiving an invalid input message when trying to create a curve between two lines. My drawing units are set to architectural. The problem is summarized as follows:
1- In Lines/Curves menu, select curve between two lines.
2-Select first tangent
3- Select second tangent
4-Select radius option
5- Enter 8'6"
6- After entering the radius I receive an invalid input message.
7- But if I enter the radius as 102 (102 inches) the curve is created without any problem.
What am I doing wrong? Can anybody help me, please?
Civil 3D is meant to work in decimal units, so it does not understand the foot symbol. Like you said, if you give it a radius as the number of inches, it works. That's because you aren't using ' . Oddly, you can input the inch symbol. Maybe because it's at the end of the input it gets ignored.
I suspect it's because the Civil 3D programmers for this command did not anticipate anyone working in Arch units.
In this particular case, you may be able to use the Fillet command which will accept 8'-6"
