Easy way to remove constraints

Anonymous — Fri, 27 Jun 2014 04:44:06 GMT

Not sure if this is an idea or a bug or I'm still a novice user:

When one draws a curve on top of another curve, and insert points on the reference curve's constraint markers (centre, line middle, etc), the resulting figure seems to become irremediably locked to the first one — it cannot be subsequently moved. I have tried removing the contraint via the Constraint panel, to no avail. Locking and unlocking curves or curve elements to reference points, should be as easy as simply clicking on the constraint icon, to activate or deactivate it.

You can delete a sketch constraint by selecting the corresponding constraint glyph (the small, white icon in the canvas indicating coincident, midpoint, etc) and then pressing the Delete key or selecting Delete from the context menu. I think that Fusion could provide better feedback that the glyphs are selectable/selected - I'll look into this.

Please let me know if this helps.

Thanks,

Charles

Haughec, thank you for that! And important to know Select button on toolbar must first be selected/highlighted in order to select the constraint glyphs. I find it important to go back to that Select frequently, to not accidently place constraints. If little message comes up saying "select objects to constrain" then need to go back to Select. Now this sketch constrainment is working great!

Wow, that was easy after reading your solution. Thank you!

While you're at it, could you take a look at why SOME constraint glyphs aren't shown at all until you hover over or select the related sketch element, even though the Show Constraints sketch option is turned on?

@chrisplyler Dude @haughec's reply is from 2014. Not sure he's even still on the Fusion 360 team.

Might have been replaced by Chad. You know what that means 😉

Aw, crap. I pulled a "chad."

What white glyph? I am so lost and frustrated right now.

These indicate constraints, such as coincident, parallel, horizontal/vertical, etc. They can be selected and deleted.

Hi guys sorry to bring this old thread again, but I can't find my symmetry constraint, it's nowhere to found. I have clicked on the constrainted lines and even all lines, but nosymmetry constraint found. My symmetry contraint is in the left and right of the rectangle points over the middle vertical construction line.
Anybody know how to remove symmetry constraint? Is it possible to show list of all constraints as in Freecad?

there is a nice parameter window but it only contains dimensions and no constraints

You are mistaken, the green axis line does not work for symmetry, therefore there is no symmetry in that sketch yet.

Drag a blue line with the mouse, the line on the other side would move

if symmetry was in existence.

Symmetry icon looks like this and will not be hidden, and 3 icons one for each selection..

If you OBSERVE what SEEMS like symmetry in that sketch, it is actually because the green line is instead constrained MIDPOINT to the top and bottom of the rectangle. So... the left and right sides of the rectangle must always be equidistant from that green line.

EDIT: Oops...cancel that. I realise that the green line isn't a sketch line at all, and that the Midpoint constraint is probably between the top line and the arc endpoint.

For anyone having the same problem, I finally found the symetry symbol is placed near one end of the symetry line. And my line is very long so i have to extremely zoom out to find it there. Thanks for the replies guys.

I have been trying to remove horizontal constraints by left clicking on the constraint symbol and then pressing Delete. That has not removed them. It has on occasion removed the dimension or the whole circle.

I have eleven circles that should have the same istance to the axis. Two are greyed the others are black. I want to change the height of all. I have constrained them and then try to change the height by giving the correct dimension. This refuses to do so. Therefore my plan is to remove the constraints, enter the proper dimension of one circle and then constrain the remaining ten with the one that has been placed correctly. What do you think of this plan? Thanks.

1. this means that they are not in the active sketch and cannot be edited.

To use them for constraints, they must be projected into the active sketch.

2. the same applies to constraints from non-active sketches

Günther, thank you for your reply. What I really want is for everything that I sketch to be active, so that I can undertake changes and corrections if necessary. Please let me know how to do that. Thank you.

Create all circles in one sketch.

Re: Easy way to remove constraints

Thank you for your quick reply. Since I already have the circles what should I do? Should I remove them all and try again? How do I do that. I managed to remove several but some remained.

I would really like to make everything in one sketch so that I can get full control of my design. How can I do that?
