I know this must be really simple but I cannot get the sketcher carbon copy tool to work.

Following the instructions:

Code: Select all

    
     Make sure you are in the edit mode of an existing Sketcher Sketch. This sketch is the target of the operation.
    Press the Sketcher CarbonCopy button.
    Click on an edge from another sketch. This sketch is the source of the operation.
    Geometry elements as well as constraints are copied into the active sketch.
    Press Esc or the right mouse button to terminate the operation. 

Example:
Step 1: create 2 sketches. One has only a circle, the other has only a square. Set both to be visible.
Step 2: Edit mode on the circle sketch. Click on the carbon copy tool.
Step 3: Try to click on an edge of the square in the visible second sketch and .....nothing happens. It does not select anything.

What am I missing?????

Careful attention to the status bar must be paid when invoking this tool as relevant and necessary information is often displayed there.

[CrashedAgain]

Watching the status bar.....
Edit mode circle sketch. Click on Carbon Copy tool.
Try to select an edge on the "square" sketch.
Status bar says sketches are not parallel, click on ctrl-alt. Both sketches are on the x-z plane ......how can they not be parallel?
So - holding ctrl-alt, try to select an edge of the rectangle.
It worked.

Are the sketches in bodies? in the same body? You may upload the file for further inspection.

You are using a branch. Did you try the official AppImage?

[CrashedAgain]

Not using bodies, I do everything in part, not part design.

What do you mean by a "branch"? The version I am using was one of the weekly builds a short while ago.

If I switch now to the "official" version (I assume you mean the "stable" Appimage), that would be a downgrade to an older version and I have gotten into serious problems doing that in the past.

[TheMarkster]

There is also a LinkStage branch.

If the sketches are truly parallel and it gives that warning, then it might be a bug worth reporting. Check the placements carefully. There could be some very tiny deviation.

In your FreeCAD infos it says

Code: Select all

Branch: (HEAD detached at 6701788)

which made me think it was a self compiled version. If you have it from https://github.com/FreeCAD/FreeCAD-AppI ... kly-builds it is exactly what you should use.

You still can upload the file for further inspection.

Both sketches were placed on the x-z plane, I just added the circle and the square without any constraints.
The Appimage was downloaded from the weekly builds, the only thing I did to it was rename it "FreeCad_Latest.AppImage" and assign a new icon to it.

Both sketches were placed on the x-z plane,

XZ is already a rotation of 90° and sometimes we see small deviations due to rounding errors. That's what I suspect here. Can you try the same in XY-plane?

Interesting, I just tried this:

• on the XY plane, no problem
• on the YZ plane, no problem
• on the XZ plane, doesn't work

If I set the the Angle property of the sketches on the XZ plane to 1,0,0 rather than -1,0,0 (what it gets by default) the CC works.

Also note, the planer value of objects created on the XZ plane in not 0, but is on the other planes.
(i.e. on XY plane Z value of square/circle =0, on YZ plane X value =0, but, on XZ plane the Y value is nm off 0)
