convert 3d polylines to 2d polyline

Mark Crane

Hi all,

Looking through the posts i can't seem to find one for this!

Is there a way to convert 3d polylines (contours) to 2d polylines with elevations?

I've used the flatten command althow it does convert them to 2d it also puts them to elevation "0". i've looked at lisp programs all over the internet but non can do it quickly, like Autocad civil3d can.

Any suggestions?

thanks

Mark

Hello Mark,

If you want to consider getting this done using an add-on tool for Bricscad, you way want to read this link to know more about our CADPower/GeoTools software which can convert 3d to 2d polylines with target elevation control:

Thanks for the reply Rakesh,

I've downloaded it but it does not pick up bricscad only AutoCAD.

Is this because I'm only using Bricscad classic?

Thanks
