Support For Stick Fonts

[yorik]

A PropertyBool was my first thought, too. Is it really such a burden?

Not really a burden, more something actually unnecessary, because it should be obvious and not something the user needs to do... But the method of trying to make a face from a simple letter L seems to work well, although, would you believe, some of the sticky fonts actually MANAGE to produce a closed loop from a L fortunately the face formed from it is invalid.

Very nice Yorik! Stick Fonts are working! No problems so far.

I also noticed that the ability to select an edge as a Sweep Path is once again working as well. Not sure which commit fixed this but it's a keeper!

Nice way to hit the milestone of 4000 commits.

Squares are swept along edges of shapes while CamBam Stick Fonts grace the top face.

Cool! But I would have expected at least a POV-Ray rendering.

It's crazy. For me the 5,000th commit on SVN was like yesterday. Time flies.

Hi Yorik,

I think there is a typo in your last commit (stricky):

Code: Select all

+ if testWire.isClosed:
+ try:
+ testFace = Part.Face(testWire)
+ except:
+ stricky = True
+ else:
+ if not testFace.isValid():
+ sticky = True
+ else:
+ sticky = True

Ah thanks for the find Chris_G fixed now.

I do hate to be the bringer of bad news, (maybe bad news), but has anyone tried exporting any of the Stick fonts to DXF format?

When I try, I get the following error in Report View -

Code: Select all

Is anyone else seeing this? Should there be a Mantas ticket filled out?

Yes there is a problem with the new DraftGeomUtils.sortEdges()... I saw it too. I'll fix that ASAP.

Not trying to do anything "productive" with it today Yorik, just testing. That is the only thing I have found buggy with it so far. Export to SVG is working 100%. Moving, Cloning, Scaling, etc., all working.

Getting better. FreeCAD is now exporting the stick fonts, but they are not quite right when opened in LibreCAD, PyCAM, or opened as DXF in FreeCAD. I'm sure your aware of this Yorik, but just in case...

Or do I have something set wrong in my Preferences?

I found a problem, single-line (stick) text will be converted twice, and the lines will overlap. I want to convert it to a cutting path, but it will still cut twice, affecting the cutting efficiency.
