Stationary - polyline

Recommended Posts

kvrle

Hello,

 

I have polyline (created from line and arc). I want to create new point/line on this polyline with input lenghts.

 

I found function divide which splits polyline on equal lenghts. I don't want that. I want split polyline on different lenghts.

 

I have axis wich represent road. I must create stationary on different lenght.

You can use the command 'LEN' which stands for length and then use the option 'T' for total length, enter the length and select the line, the line will now be the exact length you designated.

Tnx for replies but still doesn't work.

 

Measure and LEN function don't use arc for calculating. Both functions use only lines for object. Mistake on 3 km lenght is 6 m. It's too much.

 

CopyAlongCurve function doesn't give results what I want.

 

Any other solution?

LENthen absolutely does work with arcs and polylines, I use it all the time. Create a copy of the polyline and then use LENthen starting from the end farthest from the measuring point. I also don't understand how COPYALONGCURVE wouldn't also work.

Can you post a file that shows the 6m error? LEN measures the length along the polyline, even through curves.

Maybe just not using the right options

 

Here's a video showing both LENgthen and COPYALONGCURVE.lisp

 

 

The only thing those two methods don't do is actually split the polyline (path) into individual segments, but that's just a matter of placing an object at the measured points to break the polyline with.
