How to extract and draw surface profiles ?

Samu38

I'm new using BricsCAD and I would like to know if there is any internal command or lisp to draw profiles similar to this one. In civil 3d its easy to draw sections of a surface.

I mean to draw a profile from a surface or contour lines, defining a polyline or alignment. And show the profile with the terrain dimensions and the length of the axis.

Thanks you

Hello.

Currently, in Bricscad, only the geometry is available - the vertical alignment.
The table with numerical data is not yet implemented.

For now, you could investigate the Civil Site Design plugin, which includes more civil design features.

Hi

Thank you very much, we have just bought TcpMDT. However I have started to develop a lisp that will allow me to extract the profile and make annotations similar as the ones in the picture.

When I have it, I will share you, I would like to develop a set of free and open source tools for users who use cad programs for civil / mining engineering.

I have already developed the first tool that allows to place coordinates in the frame of the viewport.

All will be available at github.

Thanks you

Bit late for the party but having been a user of Civil Site Design for years, and a programmer of commercial software, it will take you years to get close to the add on software, it just not a make the profiles but massive tools regarding road design. Multi lanes, roundabouts, bus bays, sight lines to mention a few, I recieved notification re a webinar about road driveway gradings the software re-does the surface model including the driveway parameters.

The cost will be quickly recouped in time savings, have a google for their Youtube videos they show the power of the software. Pretty sure you can download a trial version.

Hi.

here is a lisp to draw 3D polyline long section.

1. draw a line or polyline on a tin surface that represent the needed cross section.
2. use "TINPROJECT" command to drape the line\polyline to the TIN surface.
3. use the lisp to draw the long section (command "LCS") from the draped line\polyline.

hope it will help.
