request: detect and show where in the sketch constraints are missing

[freecc]

If you can tell me there are 2 freedom of movements left then why not show where? If it is not too hard please make a button that can remain pressed or a check option next to "2 freedom of movements in sketch" that show where these freedom of movements are, maybe turn the points/lines to another color?

my last request. i think

There is a macro called "shaker" or "shake sketch" ( addon manager->macros) . It shall move elements that are not fixed by constraints yet.

This has been asked before, so I can point you to another resource to check before requesting: The bug tracker. You can look at all the open requests and check if that function has been requested before.

Now for the contents: Your request is understandable, but not as easy to achieve as might seem. In general there is not a special place where the constraints are missing. The solver tries to solve a huge equation system and he can detect that there are degrees of freedom left, but that's it. Abdullah came up with a promising idea to improve the situation and I hope we will see some results in 0.18.

I hope Abdullah solves it.

Some of the ideas presented in this topic may help.

This looks promising...... thanks

As I am relatively new on FreeCAD and an experienced user of CATIA V5-V6. I am 65+ now. I would like to inspire the FreeCAD development team to try to "copy" what that program does.

I try to tranlate it to FreeCAD.
An element that is not constraint is white. If it is a line then if only the direction is known the line is green, the endpoints red. for each point if the position of then point is fully constraint that point is green else red. This means that during sketching and later on constraining you can immediately see where constraining is still necessary.
If an element is overconstrained it becomes purple.

I think that this is good point for in the next version.

That doesn't sound bad - probably with different colors, but let's hear Abdullah if that matches the concept of the current Sketcher/solver.
