In order to avoid a crash after adding a page, a doubleclick onto the page icon in the document tree is needed. Then a drawing view is generated and a template can be specified.
There is may be something wrong with the document update mechanism.
Yes i did that and got the crash. BUT your answer made me try it again and i moved one of the default templates from PPA install location to the Desktop first and then specified it in dialogue and it worked fine! Now we are getting somewhere!
I inserted single view and could move it on the template by drag and drop operation. Something not possible in the past! Interactive UI supports already started to show it benefits. Simply selecting an edge or circle and pressing add dimension does exactly that. In some CAD software you need to do much more clicks to do this! In Property View you can easily set type of dimension. Trying out Insert an orthographic projection... tool still crashes FreeCAD but based on the past discussion i guess this is WIP? Did you already decide if you will keep current dialogue or do a new one? Exporting the drawing as SVG worked and i could open it up in Inkscape easily. Wonderful!
As soon as the crashing part in some situations is sorted out a bit i think this should be merged into master. Great job and to be honest if somebody would ask me just a few months back when will FreeCAD get Drawing Workbench as feature rich as this one i would say probably it will take few years! Now the solid foundation to build on is here and basic CAD operations as user would expect too.
