do endpoints of lines merge irrevocably?

[maker9876]

If one draws a line and then draws a second one, attaching it to some point along the length of the first line, then a coincident constraint is automatically applied and you can slide the point of attachment up and down the first line. Nice.

Removing the coincident constraint you can then detach the second line from the first. Good.

HOWEVER

If I draw the second line so that it attaches to the end point of the first line.... I cannot figure out how to separate them again??? Click and holding on the attachment point reveals multiple sketch curves but only one sketch point: does this mean that the end points have been irrevocably merged?

(Have come quite a long way without ever finding a solution, the workaround being to delete one of the lines temporarily to release the end point of the other. However this is problematic if other elements of the design are contingent upon the line to be temporarily deleted.)

Right click on the point and select delete coincident.

Thank you!

Just like to add to what Phil shows in the screencast, if you have several lines\curves joined at the same point you can right click near the end of the line you want to unconstrain and you get the same menu allowing you to delete the constraint at the end of that line.

In this example all the objects are constrained to the circle centre.

Right clicking near the end of the 45° line gives the option to delete the coincident constraint for just that line.

That's exactly the situation I had and had just cycled through deleting all of the coincidents to find the right one!

Additional tip therefore much appreciated.

Thanks.

Nice catch Mark. I need more coffee..it's to early...lol

Thanks @PhilProcarioJr and @HughesTooling for your usual quick and helpful responses.

Just FYI - we realize that this is not very discoverable and are working on some solutions to that problem.  Showing an actual constraint glyph for these (so you can select and delete it to break the lines apart) is what we are discussing now.  The problem with that, of course, is clutter.  You could conceivably have thousands of those coincident glyphs in your sketch.  So, we're discussing ways around that - only showing those glyphs when the point is selected, etc.   We'll figure something out, hopefully soon.

I don't think clutter would be an issue if you only show the glyph for a selection. For instance if you select a line it would only show the glyphs for that lines constraints. If you select two sketch entities show only the glyphs for those two entities. Seems reasonable.....

Something like this would help.
