Hello, anyone experiencing a delay when deleting sketch entities (lines, points, curves, etc.)? I am getting a 16s delay every time I delete something within a sketch. This seems to happen after I open a medium size assembly (244 parts, 49 unique parts, 159 mates) and then I open a single part within the assembly and try to either modify or create a new sketch. The assembly is a sheet metal enclosure with pem fasteners...I removed all external referencing and I'm still having the problem. Tried moving the assembly from the server to my local drive, same problem. It even happens after I start a new part, save it locally, then start sketching. Any suggestions? Thanks! Aron

Correct Answer

I traced the problem back to a single part within the assembly that contained a massive sketch (24,000 entities but with no relations). The sketch originated from a circuit board layout designed in EAGLE, exported as a dwg drawing, then imported into SW as a sketch. I used this sketch as a reference to trace the PCB outline and surface mounted component locations and then I suppressed the sketch to lighten the load...but I guess having the sketch suppressed wasn't enough. Once I deleted the massive sketch, the delete delay went away completely. So I would investigate parts that contain any large sketches ( suppressed or not). The part with the massive sketch only had to be open to cause the problem with any other unrelated part I was working with.

Aron,
I am not seeing anything like that. What graphics card and driver are you using? Do you have Aero theme on or off?

  Hi Paul,
  Thanks for the reply, graphics card is: Nvidia Quadro FX 3800 and driver version: 9.18.13.3182
  I haven't updated the driver for some time, I'll try that now...

    I would use this one for your card 9.18.13.3311: http://www.solidworks.com/downloads/videocarddriver/nvidia/333.11-quadro-tesla-grid-desktop-win8-win7-winvista-64bit-int…

      I didn't see your last message in time about 333.11 quadro tesla grid but I went through the SolidWorks prompts and found 340.52 recommended. Tried that driver and still having the same exact problem. And Aero theme is off. I guess a SW reinstall is next...

        No, you want the Aero them ON!!!! try that first

        The good news is that the delay is down to 14 seconds after all that effort! Maybe try the 333.11 you recommended?

Aron, do you experience this delay when you create a new sketch in a new part, or just when you edit one particular sketch in one particular assembly?

  The problem starts when I open this one 244 part assembly. Then anything I do after that (new part sketch, edit an existing part sketch, etc) results in the delete delay problem. I think the problem is only with this one assembly, not sure why, but I guess the only solution would be then make a new one, or pack and go this...hoping it will go away.

    Aron, what is the regular rebuild time on that assembly. 159 Mates are a lot to calculate in one shot.

      Hi Adrian, the rebuild time is very fast (maybe 1s or less)...the problem doesn't seem to have an effect on anything else other than deleting sketch entities.

Sounds like this assembly has what's referred to as an, "Acid part." That means when the assembly is loaded into memory, it loads one corrupted file that causes memory leaks and destabizes the SolidWorks application.
An indication that this is happening will be high-processor usage during these lacunae.
You might try going into Assembly Xpert and looking at the rebuild statistics to see if one part is registering over the top.

  Has anyone found a solution for this problem? We've got three systems with the same behavior after upgrade to 2015. All Windows 7, all updated to SW2015 from 2014, all updated to the proper graphics driver.

    Hi Steve, I found that the problem only occurs when I have this one particular assembly open. If that assembly is open...then any other part open in SW, whether or not that part is in that assembly, will have that deleting delay on sketch entities problem. My plan to troubleshoot this problem was to build a new assembly using the same parts and test each part as they're dropped into the new assembly...but I don't have the time and the assembly is already complete.

This kinda sounds like a GDI Objects issue. Is that still a problem for SW2015?

To check, go to Task Manager, add a "GDI Objects" column under the "Processes"tab, and see if it's showning more than 10,000 objects for SLDWORKS.

  Dwight, in my case, the GDI objects are only at about 1100.

I'm very surprised nobody else is having this issue. All five of our SW users are experiencing this issue and I have not been able to narrow down the exact reason. It happens every time any one of us has an assembly open that has parts that reference a large sketch. Even if the part has no ties to the open assembly, it takes forever. Close the assembly and it works fine. That doesn't help when the sketch contents need to be replaced with something inside an assembly.

For example, the one I am working on now, deleting one point takes 1 min 30 seconds. That seems to work out per point, or sketch entity. I just waited a half our for a load of sketch entities to delete. We've found some of a workaround, in using power trim, but that can't always be used (like with points).

I'm having the same issue, it just started within the last few weeks. It takes 4-5 seconds per entity being deleted. For example, just now I selected 15 lines and pressed delete, and then the cursor spins and the program is unresponsive for a little over 1 minute.

I am using power trim as a workaround, because that works instantly.

we have the same problem. power trim, or window the entities/make a block/delete the block, are the workarounds we're using. the block thing doesn't work for 3d sketches I was told today that SW has about 12 issues in queue ahead of this one, to be fixed. we have major problems with camworks too.
