Smart Dimension

I Can't find this anywhere in LibreCAD (2.1.3 or 2.2.0(124)):

Are "Smart Dimensions" included in the current release or planned for a future release?

By "Smart Dimensions" I mean the dimensioning of objects by selection of an edge; this instantly generates a dimension line parallel to the edge, much the same as a diameter or radius is generated by selecting a circle, rather than having to select the two endpoints of an edge with the horizontal, vertical or aligned tool.

I would also really like to see 'Smart Dimensions' or something similar implemented in LibreCAD. It is one of the best features of Solidworks and really speeds up the drawing process. For those unfamiliar with it, the big advantage over 'the ordinary way' of dimensioning is that you can go back at any time after object creation and edit the dimension, and the object size will change accordingly without having to delete the object and redraw.

Strongly support it as a feature of LibreCAD.

This is the concept of constrained by dimensions or expressions.

The current design is weak here:

1, we don't have a constaint system;
2, there's no smart entities either(with some dynamic parameters/mathematical expressions);
3, there's no topological entities.

Good morning

Maybee we don't necessarily need a constraint system for this...

For example, when dimensioning between two lines:

- Click on the 1st line
       An aligned dimension is directly attached to the mouse.
       The dimension can be dropped as normal.

      However, if you click on a 2nd line:
         The system checks whether these two lines are parallel:
         - If yes, an aligned distance-dimension is attached to the mouse.
         - If not, an angle dimension is attached to the mouse.

This is just a simple thought of mine, which you can deepen if you are interested, and could take LibreCAD a huge step forward.

Kind regards,

As I see it for say a line it is defined by 2 points. I'd expect you could say double the length from properties but there is no length property on the line. Even if it did, which way would it extend? From the start, Middle or End of the line?
