I’m having a problem entering non-tangent horizontal curve data. TPC automatically corrects the curve data to be tangent. How do I enter this data without issues? I also would like to know how to display multiple line tables and label each one uniquely (example L1, L2 for one and CL1, CL2,CL3 ETC. and have editing capability on the Line Table Text. It’s always the small things that seem to hang me up. Please send me an email should you want to discuss over the phone. I’m at the home office today. I don’t want to post my home phone on the forum.

See the help topic Horizontal Curves, Entering Curves as you go.
TPC assumes curves are tangent unless you tell it otherwise by entering any data that specifies the orientation of the curve. These would be incoming direction (PC->PI), PC->PR direction, chord bearing, etc. All of these are most easily done while entering the curve in the Traverse View, but you have to include those columns in the traverse view format. In the Curve dialog, you have to learn about holding/releasing curve data to accomplish this.
Multiple Line Tables
TPC currently allows just one table of each type (Lines, Curves, Lots, Points). We will be adding the ability for multiple tables soon.
Editing Table Data
To edit any table data, just right click it in the table.
You can also add record data by appending a ; to the end of the table entry while editing it, then adding your record data after that.

I found that if I use the calculate coordinate point then enter the corresponding point number into the traverse it will work. If there is another direct way to accomplish this please advise.

If I am following you and you are using COGO, Compute Coordinate to create the PT, you can do the same thing directly in the traverse view by entering the chord bearing/distance to create the PT then enter one piece of curve info, like the radius.
Let me know if this takes care of it for you.

That helped! Thanks
