Add Aped Distance and Tangent Length In Curve Label

[nirmal.maisuria]

Hello Everyone,

I'm just unable to find length of "appex distance" and "Tangent length" property in "Tangent Intersection Label Style".
I hope , any one of you can help me.
Thank you

Nirmal,

The Apex Distance is also called External Distance, the nearest distance from PI to the curve.

You'll need to create an Expression:

{General Segment Curve Radius}*((1/COS({General Segment Total Angle}/2)-1))

For Tangent Length, use "General Segment Curve External Tangent".

Hi Dave,

I was wondering why I would be getting no answer and just ??? for this formula. I calculated it manually and I am getting a number.

I just used Dave's expression and it worked. I did it for an alignment so I had to change the properties a bit but it worked just fine. Can you screenshot your expression?

Hi Brian,

I was able to figure it out. It had something to do with the style type I was using.
