Re: Arch Window from Python - hinge problems and edge IDs

I'm using construction lines so that I can use equality constraints to keep things like width of the lead came between the glass panes the same width, with the aim of making it easy to tweek a window's geometry by just modifying a few named constraints. In heindsight it is rather obvious that the en...

Re: Arch Window from Python - hinge problems and edge IDs

Thanks chrisb for your thought but I don't think it is that but I do think I've found out what the problem is. I'm using construction lines to keep things in the right place. This works fine until we come hinges. When creating a sketch the construction lines add to the edge count. However when compl...

Arch Window from Python - hinge problems and edge IDs

Hi, I have to deal with leaded windows in old houses like this quite a bit: fc_window.jpg So I've written a script to generate sketches which are then fed into ArchWindow.makeWindow. It all works fine until I try to add a hinge to to the top right casement (I know there isn't one in the photo above ...

OBJ importer error (python 3.7)

Hi, When I try to export an OBJ file (such as when uploading to Sketchfab) I get an error like: Traceback (most recent call last): File "~/.FreeCAD/Mod/WebTools/Sketchfab.py", line 220, in upload pack = self.saveFile() File "~/.FreeCAD/Mod/WebTools/Sketchfab.py", line 138, in saveFile importOBJ.expo...

Re: Civil engineering feature implementation (Transportation Engineering)

May be we have to add an extra scaling factor for z in this case. Can you post the lat/lon coodinates of your terrain, so I can compare it against other height sources to find the right factor. I've just found this about the EA LIDAR data (https://content.historicengland.org.uk/content/docs/researc...

Re: Civil engineering feature implementation (Transportation Engineering)

I'm having some getting a sane mesh or point cloud from LIDAR data published by the Environment Agency in the UK. The point cloud created during the initial import looks good but when I try to create a new point cloud or mesh it is no longer sane. To me it looks like a possible scaling problem on th...

Re: Geo Data and BIM

Would PostGIS provide a good data source? It is widely used in the GIS world and TIN (Triangular Irregular Networks - think of a triangular mesh) DEMs can be fetched/used from it depending on the original data source. Also there are already lots of tools to import data into PostGIS from various sour...

Re: Help test FreeCAD for Mac

Hi, Thanks for all the hard work getting FreeCAD working on the MAC. Everything works ok for me apart from the Drawing workbench. When creating a drawing on the mac version I see what look like previews of other tabs that are open (apart from the start page). A screen shot is below: mac_drawing_erro...
