FreeCAD Trails Workbench (Transportation and Geomatics)

I implamented the contours in new surface object. Contour interval option added to data properties.

You can see how it's works in video.

You need to figure out how to make GIFs. Then I could use it in my presentations. It looks great!

(Honestly, though, I never could figure out a good way to do it in Windows.)

Thanks you can use this app for gif https://www.screentogif.com/

Also can you use SoGeo nodes for your alignments?

I did it for point groups and surfaces. I will do it for guidelines too. But firstly you need to do it for your alignments.

I've been working to reimplement pivy_trackers... it's been a long, slow process. I'm going through and cleaning up the code base a bit.

I tried to implement SoGeo nodes, but didn't have much luck - something wrong with the way I handled it. There needs to be a common tree heirarcy for the SoGeoOrigin as there can only be one in the tree. So I think as long as we can establish a common SoGroup (I might suggest a Switch-Separator pair) that lives at the top of the scene graph where we do all of our work, it shouldn't matter.

I just using this code for SoGeoOrigin. İt's working good for me. Then I just create a SoGeoSeparator in attach function and add all nodes in it and using SoGeoCoordinate for points.

SoGeoOrigin:

Attach:

Ok. I'll try to take a look next week and see if I can figure out a structure.

Ok

Hope this is an acceptable place to ask the questions.

Read in a recent note on here that installing the trails wb using the add on manager is now deprecated.
So I removed the add on manager version and started installing the bits to get a working trails wb.

(looking right now the trails wb is listed as alpha - - - is that alpha of the newest iteration or ???)

Git clone and parked that in .FreeCAD/Mod/ .
Wanted to also install cv2, gdal etc in the FreeCAD/Ext folder (as was suggested).
Tried install the python version of gdal using pip - - no joy.
Tried using a tarball version - - - downloaded from Debian - - - also no joy.

Am I pushing the curve here (just wait) or is there a better way to achieve installation of the packages for geodata functions?

TIA

Just install it by using git. That's enough for import osm.

OK - - - trails wb is installed. (Using git.)

How do I install cv2, gdal, gdalconst, urllib, chardet, certifi, idna - - - please?
