How-to determine global coordinates of a circle or arc?

[ppemawm]

Thanks to triplus and mario 52 for their valuable time to continue to look into this.

Now if that is the way to tackle this or is it more important to have less clutter in status bar by removing the text after 3 seconds i am not sure.

I would vote to have the information in the status bar stay only for a given mouse selection until the next selection. That way the coordinate(s) could be easily copied and pasted into an input field.

For now, the toolbar macro that triplus shared is quite adequate.

I don't know if this is a bug or desired behaviour but based on my tests "Preselected:" message is always displayed. That is hovering the mouse over 3D objects shows current coordinates and the message is removed after 3s of hovering inactivity. And there currently isn't any "Selected" message.

I guess if time value would be removed "Preselected:" message would always be displayed and that could make sense. But there is one piece missing currently and that is once there is no preselection under the mouse the message should be removed.

hi
with this macro you have the statusbar info and Triplus info (but the macro stay resident)

Code: Select all

    print "run .."
    def addSelection(self,doc,obj,sub,pnt):  # Selection
      
        print doc    # document
        print obj    # object
        print sub    # sub object
        print "Coordinates point mouse     : ",pnt    # coordinate point mouse

Yes using selection observer for sure makes the end user life easier. As in a way this is "continuous mode".

And additional benefit when using macros is copy/paste works. Therefore i guess the only solution left that could further improve this in the future is to add "pick a point" tool directly in the placement dialog. But then i guess it could work too fast and it could become to easy. Probably you would need something like a driving licence for it.

For testing purpose i increased it to 10s and to be honest writing the number down on a piece of paper if it has a lot of decimal places. And for all 3 coordinates... Likely 10s wouldn't be enough. Therefore i am not sure if it would make any sense in increasing this value as likely 20s would need to be set. Now if that is the way to tackle this or is it more important to have less clutter in status bar by removing the text after 3 seconds i am not sure.

I would greately appreciate the display in the status bar for at least 10s. I cannot remember how often I wanted to have just a quick look at the coordinates and it was always this fiddling with mouse over-off-over. I need it e.g. when I double check some hand written gcode based on the model (yes I use path WB as well).

What about having the option to write the informations into a multiline textwidget/report view?
So we can copy and paste them?

Would be ok for me, although I would like to be able to turn it off in report view. I don't know anything about the internals of the Tools->Parameters, but just for displaying it seems a natural approach to configure the display time there - perhaps with the option of entering 0 for indefinite.

The amount of info would likely beat the purpose.

Yes the original request was to increase the time as current time is set too low and it causes usability issue. Therefore this could be resolved and i can make pull request and set the time to 10s. If Preselected message would be cleared when mouse is going over places without anything to select message probably could be set to always on. But this isn't the case therefore at best i can help with increasing the time to 10s for now if that makes sense to others.

This works for me.

I find that after several years of routinely using FreeCAD as a consulting engineer creating parametric models and assemblies that 80% of the time I use the information in the status bar is for coordinates either for Center in Placement or for Sketch offset. Having time to record one or more of the coordinates would significantly assist in work flow. Unfortunately it doesn't seem that you can copy and paste from the status bar. For that case, the above macros are most helpful.
