Hello there,

 

Upgraded from SW 2012 to SW 2016 recently but I'm having a weird issue with dragging sketch endpoints. I can drag them, but a tiny movement of the cursor moves the point by a huge amount, and I cannot drag it back to it's original position.

 

Anyone with this same issue?

Re: Weird sketch endpoint drag behavior

It sounds kind of like you are not viewing the sketch parallel to the screen.   So that when you drag a tiny amount, it only moves that amount parallel to the viewing screen, but in reality, it slides a few inches.

 

Could this be the case?

 

As a side note, I have found it to be better to dimension the end point, then change the dimension, this way, view angles don't have any effect on the amount that it moves.....you are using actual numbers.   Even if you delete the dimension afterwards.

 

But, that being said, if you delete the dimension afterwards, you should make sure that your sketch is fully defined before you are done with your model.  If it is not fully defined, then some unpredictable behavior can happen when you are dragging things or changing things upstream.  (which might be exactly what you are experiencing)

Re: Weird sketch endpoint drag behavior

Can you attach the *.slprt file here that is exhibiting this behavior?

Do you see the same behavior on any new part?

Re: Weird sketch endpoint drag behavior

I'm having this exact same issue with every sketch item.  It must be a setting, but I can't seem to figure it out.

Is it possible that you have Grid on but not displayed? And are snapping to grid?

Re: Weird sketch endpoint drag behavior

I'm not snapping to anything as far as I can tell.  The action is very smooth.  I grab the center of a circle, or the endpoint of a line and start to move my mouse.  If my mouse moves a quarter of an inch the object moves maybe 2 inches in that direction.  The farther I move my mouse in that direction the farther the object moves.  It is smooth and controllable, and enormously irritating...

Re: Weird sketch endpoint drag behavior

Like J. Mather said, attach a part that is having this behavior (even a sample part) and let us look at it.  What version of Solidworks?

Re: Weird sketch endpoint drag behavior

I am also having this problem. Strangely not in all sketches. Spline endpoints and sketch points, unless they are constrained to something. Here's a file. Try editing the spline endpoints in Sketch 1.

That's really strange. Just as Massimo Cubeddu said, once you've dragged the endpoint you can't even put it back where it was!

You have to undo.

Dragging the endpoint of the c/l in the same sketch acts the same way.

Dragging the end point of the angled line, even though it is constrained to the line.

SWX version doesn't seem to matter I'm SWX 2017 premium SP4.0.

I've never seen this before.

Re: Weird sketch endpoint drag behavior

I can't open your file (I am using SW 2015), but based on other's suggestions, it might be a great idea to show this to your VAR.

 

Maybe Matthew Lorono or Jim Wilkinson might have an idea.

Re: Weird sketch endpoint drag behavior

Lofts are strange and complicated creatures.  If you delete the loft, Sketch 1 behaves as expected.  The planes created after Sketch 1 (which are dependent on Sketch 1) are influencing the behavior of Sketch 1 after the loft has been added.  You can work around this by creating a second Sketch immediately after Sketch 1 which is just a duplicate of it (via Convert Entities).  Constrain the ends of the converted spline to the original and then use the new sketch to create the planes and the loft.  Sketch1 will stay at the top of the tree and will no longer be influenced by later features.

Actually, this looks like a problem with Instant3D. If you keep the loft, edit Sketch1, turn off Instant3D, and drag the sketch, it works fine. If you turn Instant3D back on again, the problem occurs again.

 

Sabs, I would suggest submitting this model to your reseller with this information so that they can submit it to our technical support team and get an SPR for the errant behavior.

 

Thanks,

Jim

Re: Weird sketch endpoint drag behavior

Unfortunately, SPR 744789 is listed as fixed:

So, 944916 is not the same problem, or there has been a regression.

Re: Weird sketch endpoint drag behavior

Hi Jim,

 

It's a different problem. 944916 was first logged with SOLIDWORKS 2015 and 744789 was fixed in SOLIDWORKS 2016 so if they were the same problem, 944916 would have also have been fixed in 2016. And, there is nothing to say that the various reports in this thread are the same exact problem, even if they are all cured by turning off Instant3D.

 

This is why it's VERY important that if a problem is related to part/assembly/drawing data in any way, even if it sounds like the same exact problem by an SPR description, that the user report the problem with their data and steps to reproduce through the reseller so it can be logged. Even if SOLIDWORKS Technical Support *thinks* it is the same problem and logs the new instance against the same SPR, they will log it with the new user's data and steps to reproduce along with the other data and steps already with the SPR. Then when the developer is troubleshooting the problem, they evaluate all cases against the SPR and fix them all since the different cases may exhibit the same symptom but are actually a different problems in the code.

 

Thanks,

Jim
