Fork of FreeCAD/FreeCAD, with some stale branches and some work in progress.

Deleting view group should also delete views

Currently, the individual views end up orphaned

remove need for ..._WITH_OVERRIDE macros

FreeCAD#570 (comment)

Apply all properties to views before drawing

Sometimes when adding a view, the scale isn't yet applied to the view which creates weirdness.

Rendering of large-scale objects

Things get really slow when a Drawing of a really big sphere is requested - investigate this

Finish edition of template texts

• Python interface - changing strings, also setting view orientation while there
• Show PropertyMap in PropertyEditor?
• Escape user strings + handle SVG errors better (currently throws unhandled exception)
• DXF support?
• Add blank template option, would be good for error cases like above
• Bigger minimum size for template string dialog

Weird behaviour on changing "Front"

1. Create drawing with an orthographic group and a few views
2. Save
3. Restart FreeCAD and open the drawing again
4. Edit orthographic group to add another view
5. Click buttons to change "Front" view, notice that the newly added views don't change every time the other views do...

Limited dimensioning possibilities for revolved objects (cone, cylinder)

In https://github.com/WandererFan/freecad-dev/wiki

some edges are missing "reference" to OCC edge. --> can't select and can't calculate dimensions.
not all projection edges have an equivalent in Source. (ex for a Sphere, projection has a circular edge, but Source Sphere has no circular edge)

The problem seems to be bigger. Cones and cylinders have only one selectable edge (slant height/height), two vertices and top/bottom circular edges. This makes eg. dimensioning cone angle impossible.

Workaround ideas:

• add some additional OCC edges, vertices eg. 4 slant height edges (0, 90, 180 and 270 deg) - may be tricky, and will be a waste of resources
• use 2D edges edges after projection, similar to Hamish's python Drawing Dimensioning workbench - only for projected edges, mess on code and in FCstd file
• other ideas?

Use PropertyMap for editable text in Drawing

Fix crash on drawing of turner's cube stand

Although it looks like this might be in OCE...

Bounding box calcs wrong for cones?

1. Create the default cone in Part
2. New Drawing
3. New view group for the cone, add all views
4. Note that views overlap

Properly dimension isometric views

See blog post: https://opendeveloperfunding.wordpress.com/2015/04/18/geometry/

Root cause of the problem may be that the 3D information is lost during the projection to 2D?

Can't open new 3D viewer if last one closed?

1. New document
2. Create Sketch
3. Pad out Sketch
4. Create new Drawing of Pad
5. Close 3D window
6. Seems impossible to open new window without closing/reopening document?

Investigate crash when using helical test script

Doesn't actually make a helix yet

import Part, FreeCAD, math, PartGui, FreeCADGui
from FreeCAD import Base

get the selected objects, with first selection for the trajectory and second for the section

selection = FreeCADGui.Selection.getSelection()
try:
shape = selection[0].Shape
shape2 = selection[0].Shape
except:
print "Wrong selection"

section = Part.Wire([shape])
section2 = Part.Wire([shape2])

create Part objec in the current document

myObject=App.ActiveDocument.addObject("Part::Feature", "Helix?")

variable makeSolid = 1 to create solid, 0 to create surfaces

makeSolid = True #1
isFrenet = True #1

trajEdge = Part.makeLine((0, 0, 0), (0, 0, 10))
trajWire = Part.Wire([trajEdge])

create a 3D shape and assigh it to the current document

Sweep = Part.Wire(trajWire).makePipeShell([section, section2], makeSolid, isFrenet)
myObject.Shape = Sweep

Fix regression - moving front view with measurement highlighted

Caused by the front view not stealing focus from anything other than views, or perhaps that's not the right approach anyways. -Ian-
