Feature: offset tool in sketcher

[edi]

I am sorry, but I think its not a problem of the macro, but an installation problem.

Did you find the files in your computer ?

You can look for accessible python modules in the console. Just type

Code: Select all

>>> import DraftTrackers

Hopefully somebody else using 0.19 can help us ?

Running "import DraftTrackers in the Python console gives:
.

Code: Select all

Python 3.6.10 (default, Jan 16 2020, 09:12:04) [GCC] on linux
Type 'help', 'copyright', 'credits' or 'license' for more information.
>>> import DraftTrackers

I just checked the source master, which was updated about an hour ago. There is no longer a DraftTracker.py module in FreeCAD 0.19.

I did find it in an older version 0.18 I have on my computer, but Draft WB has been completely redesigned since then.

On Latest 0.19, for DraftTrackers try :
import draftguitools.gui_trackers as DraftTrackers

and remove original DraftTrackers import.

Thank you @edi for this great feature

I may add that some kind of continuation mode would be great: just select one edge and all subsequently connected lines are offset as well.

I will keep this idea in mind.

You could use Path_SelectLoop feature for that maybe. Just my 2 cents. (BTW it's already pretty convenient to use it by gui, as an end user I mean).

... import draftguitools.gui_trackers as DraftTrackers

It works like a charme, thank you @Rana.

About OffsetInSketcher03: works fine, sometimes overconstrained, but it's easy to autoremove redundants in sketcherWB.
Thank you again!

Testing version 3.
Freecat quit when make a a offset with popup winfow that says "Inner radius becomes negativ"

[edi]

Imagine the radius of your original arc is 3. If you want to create an offset line in distance 4 at the inner side, the radius becomes -1. That is not possible, so the script stops. The outside radius would be 7.

[Pauvres_honteux]

... the radius becomes -1.

And that is exactly why you must add

Code: Select all

.... if radius <=0 then trim offseted lines/curves at intersection ...

to your macro.

[Pauvres_honteux]

Here's a guy who created a macro for extending lines. Have a chat with him and see if you can get forward from that chat.
.

Extend :

Select a cosmetic edge and run the macro :

Enter a value for the Start point (marked by a red circle on the view) and end point, then click on "OK" to execute one time and exit or use "Apply" to do the action more than one time.

And that is exactly why you must add

.... if radius <=0 then trim offseted lines/curves at intersection ...

to your macro.

Thanks for that idea, I will reflect it. The problem is not the calculation of the intersection point. The problem is to keep the overview when numbering lines, arcs, edges etc. if the offset lines are less than the original lines.
