Re: Very Weird Sketcher Behavior

@chrisb: No, I explicitly picked the external-geometry reference tool, the blue parallelepiped with the arrow pointing towards an edge above it. While selecting the edges, the tool shown was a table with the three legs and the aiming crosshairs, which I used to select each edge by clicking.

Re: Very Weird Sketcher Behavior

All you have to do to reproduce the generation of the two splines is: Delete the sketch in the file 'bolt.fcstd', so you only have the 3D bolt only (this step is not strictly necessary) Select the flat annulus on the head of the bolt Start a new sketch and bind it by "Flatface" to the annulus above ...

Re: Very Weird Sketcher Behavior

I guess I answered my own question. I was able to pick individual vertices of the regular hexagon for external geometry reference. I was under the mistaken impression that only edges can be picked for external reference. I deleted the bsplines (this made the sketch unconstrained with 6 DOF, as expec...

Re: Very Weird Sketcher Behavior

I, too, wondered about the bsplines. The bsplines were generated when I picked two sides of the regular hexagon for external-geometry reference. If I delete them, I delete the external geometry references. How else can I constrain the points each to a vertex of the external regular hexagon? And why ...

Re: Very Weird Sketcher Behavior

LOL, not far from the truth! On a more serious note, I opened the fcstd file I submitted to this thread (after having shut it down). When I got into the sketch, it was difficult to find it so I can center it to the display and when I finally did, only the external-geometry edges were visible. After ...

Re: Very Weird Sketcher Behavior

Sure. (Dumb of me not to post the fcstd file!) Here it is. I just verified that when I try to constrain the third point (make it coincident with one of the endpoints of the remaining edge), I get an over constrained sketch. This time the bolt's view did not disappear from the sketch.

Very Weird Sketcher Behavior

In the recent versions of FC17 I've been observing some very weird behavior with sketcher. I think that sketcher erroneously declares the design overconstrained when the last of three points with 2 degrees of freedom is constrained and also has problems with graphics. Full details below. If this tur...

Re: Dimension "Snap Points" in Draft WB in Imported STEP File

Some updates to this. It seems that in the past couple of versions the problem was corrected. But after I updated last night, the problem is recurring. Here are the data after the latest update last night: OS: Ubuntu 16.04.2 LTS Word size of OS: 64-bit Word size of FreeCAD: 64-bit Version: 0.17.1112...

Re: Dimension "Snap Points" in Draft WB in Imported STEP File

Yes, I think easy-fw is correct. The problems occur on imported multi-part .step files. I would like to issue a small correction to my initial post. The problem persists after I save the imported multi-part .step file as fcstd and load it as such.

Dimension "Snap Points" in Draft WB in Imported STEP File

This is my first post on the FreeCAD forum. I did search too make sure I am not repeating here somebody else's finding. I have observed that in recent versions of FC17 (as of about the past month or so), when I try to snap at endpoints, midpoints, etc., to get a linear dimension in Draft WB in a mod...
