Civil engineering feature implementation (Transportation Engineering)

[Joel_graff]

That is pretty neat!

It looks like a spline-based implementation, which is generally useless for traditional transportation engineering design. Microelly and I spent several weeks trying to figure out how to design a spline that reduced to simple curves. I'm sure it's a solvable problem, but not within easy reach at this point.

Some of the alignments dont throw any error but labels looks not aligned.

Can you take a look again? I've imported the alignment, turned on labels, saved it, reloaded it, and it looks ok. The only issue is, if the alignment is saved with the labels turned on, it still reloads with the labels turned off.

I'm not convinced it's ok - I suspect there's something that's not being reloaded properly, but I can't consistently demonstrate a bug to squash.

Anyway, sorry it's taken me so incredibly long to work this out. Work has been getting busy these last few months.

I dont think that a good idea to save and restore model from xml file. So I think my model keeper property working well. Because your solution couse permission errors. But we can use your exporter to export xml files to use with other softwares.

That's fine. I was just trying to follow up on this bug - it looks like it's working fine, now?

I dont know. I didnt test it and I wont until next monday.

It works. The shape of alignments looks normal and create guidelines normally but throw this error. Also its complately not working for d1 kolu.

Hi All,

If this is the wrong place to post this sort of question, just let me know and I can remove/post elsewhere.

I am trying to install Trails to be able to import some pretty high-res lidar data. However despite extracting trails and the privy_trackers (and the python support scripts) from github, the Trails module still doesn't seem to want to run, and I get the message below in the report:

Code: Select all

    return original_import(name, *args, **kwargs)

Am I making a stupid mistake here? I appreciate any pointers in advance.

Hi HakanSeven12,
recently I stumbled across a strange FreeCAD behavior ... see following thread:
[Draft] Issue entering point in 3D view
I was wondering if the issue is related to Draft WB or to Trails WB?
Do you have any idea?
Thanks for your valuable help
