Export cross section polyline to csv ot txt

[Rabindra Bhatta]

Hi guys,

I would need a lisp for exporting to csv or txt file 2d polyline vertices from a cross section based on the picks:

1. pick the chainage

2. pick the 0.0 offset line

3. pick the reference level line

4. pick the reference level elevation text

5. pick the polyline for exporting vertices

 

The lisp would calculate offsets and elevations comparing to picked 0.0 offset line and given reference level.

 

the data exported to csv/txt file would have structure like this:

 

chainage

offset on the left;elevation

(...)

offset on the right;elevation

(...)

 

for example:

25+500

-5.0;212.22

-3.0;200.50

1.1;205.69

4.6;202.37

 

25+600

-2.0;213.22

-3.0;201.50

5.1;205.69

6.6;202.37

 

25+700

-4.0;202.22

-2.0;220.50

5.1;212.69

8.6;212.3

 

Does anybody have a code which could be used for developing such workflow?

I have limited time at moment but for any one here is code close to what is wanted. A good starting point. Happy for some one to enhance.

 

I will comment though that Civil site design a CIVIL add on will create reports of all cross sections etc in one go including XYZ of points.SurfaceRL.lsp

Thank you very much.

Hello, this is similar to what u need so try

List points relative coords from section view to CSV.lsp

Just a comment

 

(setq station (getreal "\nEnter station : ")) can use entsel and get text value

          base_height (getreal "\nEnter lowest height : ") can use entsel and get text value

 

Have a look at Lee-mac Parse Text which is in my surface RL.lsp.

mine is the case where u don't have an object with station and/or base height (or it is part of some block or few mt lines)so u can't select it
