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...

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...

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 ...

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 sav...

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...

The location is 50.8041221,-2.278285 (https://www.google.co.uk/maps/@50.80412 ... 285,16.49z)

Thanks!

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...

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...

Hi ickby,

Thanks for letting me know. I look forward to the update when that happens.

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...
