In my thought there is even no need to select construction line as axis of symetry. That's why I talked about "left" and "right" side to define the doubled dimension, in a relative manner, relatively the dimension itself. It's axis agnostic.
BTW, the selection of a construction line as axis of symetry would be great for sure and more similar with big cads, but it involves more work to code I assume.

For me it would be sufficient to have
- for defining such dimensions a drop down menu icon like we have for diameter/radius
- for display something like this:

This could hopefully keep things simple, because in 3D view nothing has to be changed except the text on the dimension.

An idea of behavior; With radius or diameter constraint ISF you select 2 points or line, it can insert the radius constraint or diameter on the flat line. Maibe some separation between constraint and the line is required to not overlap the constraint and the flat line.

I personal don't like drop down menus for everything.
I'm quite sure that i'm as a user know what i want. Most cases software can faster follow based on my input as that i can follow software on his required input.

So if i need a diameter and i select a circle there are (for the solver )not much options what i want. If i need a diameter for a revolve and i start with an axis then (for the solver )i have also a select set of options.

On the notation i understand what you meant... but doubting if it's more clear as adding a diameter symbol / a line that extend on the other side of an axis. My main reason for my doubt is ambiguity

You are right, applying a diameter to a line could have the meaning asked here for.

I still think construction circles are the better solution within the sketcher:

As you can see, some arrow heads disappear if I deaktivate the grid. :shock:

I haven't seen this before. Can you open a new topic and attach the file to it? Did you try resetting the config?

huge clutter IMO, at most I would use a small arc:

C'mon it's a sketch not a drawing...

If you use arcs, dont't forget to lock their end points or the sketch will be under-constrained. 8-)

I don't like the idea of adding (construction )circles...
So if it is added please make a property that i can put them off
