How to remove several constraints at a time?

tj_thornileytj_thorniley Member Posts: 65
I often want to revisit a previous design and make small changes, tune the dimensions, etc.
But every time I do that, it ends up over constraining the sketch, or some similar issue.
How can I remove all (or several selected) constraints in a sketch, all in one go?
As opposed to clicking every single one and do it individually?

For instance, I 3D printed a prototype, and turns out i need to change a dimension from 15mm to 19mm, but it became over-constrained and broke the whole sketch.

    Hi.

    Currently you can only do them one at a time I'm afraid but there are IR's for changes to this.

    The trick is to fully constrain the sketch the first time around, and then change those dimensions on the edit rather than to add new conflicting ones.

    Pretty sure that's exactly what happened.
    Then all I did was increase the value of an existing dimension by 4mm.

    Above you have a 19mm dim conflicting with a 15mm dim.  You also have blue unconstrained geometry.

    That's right. I increased one dimension from 15mm to 19mm. That's 4mm. That's what I'm talking about.
    Actually, just noticed I dimensioned the same gape twice at two different points.
    I thought you were referring to the one on the opposite side that is linked symmetrically.

    Anyway, it seems to be working fine now. I didn't have to add constraints to the blue geometry, in this instance at least. 
    Still it's something I encounter often. Would be nice to have that extra control over the constraints. Maybe a keyboard shortcut.

    I just found a neat trick for that. If you view the sketch from orthogonal side e.g. Right in your case
    Then the constraints are shown off the plane and it is easier to select (dragging from the left or right) the whole bunch and delete them. smile:

    Anybody find a way to delete all constraints?
