It works indeed as a alpha version.. congrats for the package and happy to dive into its possibilities!

Great!

Hi Joel. I writed a GeoOrigin FPO. It can create a SoGeoOrigin node and edit its properties. You can get it by using this code.

Code: Select all

from freecad.trails import geo_origin

origin = geo_origin.get(vector)

If there is an object funtion returns it. If not, function will create a new object. Vector is optional. If origin.Origin is (0,0,0) it use vector variable as origin. It has two properties.

Code: Select all

zone = origin.UtmZone
geo_origin = origin.Origin

Also I added folders under it.

Excellent!

I'm still working through some refactoring on my code, so I haven't had a chance to really look at this yet. I'll try to soon, but I just don't know when.

I think I understand why there is a GeoSeparator node. If your coordinates has same system with your GeoOrigin you dont need it. But if your coordinates has not same system with GeoOrigin you can use GeoSeparator to define another system to scenegraph origin. That gives you to ability of use different coordinate system values in same scenegraph.

For example, you have two point file. First one is utm coordinates, second one is geodetic coordinates. You can create GeoOrigin with utm system for first file and you can use GeoSeparator with geodetic system for second file. Then you can convert your GeoOrigin origin coordinate to geodatic coordinates and use it as GeoSeparator origin coordinate.

That would be very helpful when using multiple coordinate systems in one scenegraph.

Hi Joel. The xml importer throwing some errors when I try to import any alignment. I can't send the report because I don't have a computer for now. Can you take a look when you have time?

Maybe I can help. Tried to import @HakanSeven12 xml-file
"A Kolu Güzergah.xml"
and got probably the same errors

Thanks. Yes that is the error that I talked about.

Is it possible to install trails on windows without installing git?

[HakanSeven12]

I didn't test with addon manager. I'm using visual studio code and git assistant to pull all files. But you can manually download repos an put them where they should be.

Either manually download nor AddOn manager will fetch the submodules.
