FreeCAD Trails Workbench (Transportation and Geomatics)

[fdunn1ca]

I am trying to create a model of my front yard and ultimately some re-landscaping.
I am pretty much a FreeCad newbie though I was quite fluent in SolidWorks in the past.

Using "Trails (alpha)/Point Tools/Import Point File" I tried to import a space delimited text file. I didn't get preview data but got this error.
Any ideas on what I am doing wrong?

Thanks for the quick reply.

I attached a screenshot and clicked the "Place inline" button.

Hope that works. Still learning how to use the Forum.

You need to write a number to description box too. That cause the issue.

That worked.

This is very cool. I created a surface from the point group. Now I have to figure out what to do with it.

Can you point me to any documentation?

Thanks,

Frank

The problem is there is no documentation for trails for now. If you created a surface you can edit it by using surface edit tools. You can import alignment files by using alignment importer. You can create regions(like civil3d sample lines), sections. Than you can calculate areas between sections and print a volume table.

Hi Hakan,

Thank you so much for creating these tools and for your support. It looks like I have a lot of learning to do. I'm thinking I will try and figure out how to make a solid from my surface then use the Arch workbench to model my house on it.

I am a retired mechanical engineer so new to all this. What is alignment in this context?

I realise this is above and beyond supporting the Trails tools so if you are too busy please don't feel you need to spend your time teaching me.

Thanks again,

Frank

This workbench for road design son if you don't have interest on this topic you don't need to learn it to you can stick with point groups and surfaces.

Some visual fixes for alignments.

Some more tools are added to Trials this morning. 2D/3D PDOK data with 2D BGT with first quick and dirty version of 3D CityJSON.

And some basic documentation about how to use the tools: https://github.com/joelgraff/freecad.tr ... /GIS-tools



Any feedback/testing is very much appreciated!
