Fit Spline slowing down, then stopping

Christopher Vitela Jul 25, 2013 3:00 PM

Hello,

I am having a problem with my fit spline command with the "Select Chain" option causing Solidworks to stop working. Below is a picture of what I am trying to create the fit spline on (highlighted section):

My fit spline seems to be working on everything else, but when I try it on this section, it starts working fine, then slows down along the path, then it just stops going and I am left with my mouse cursor as the right click for green check mark image. No matter where I move my mouse, it stays as that image and I have to go to the task manager and end Solidworks. I'm guessing it is just because the spline is so complicated, but that shouldn't be a problem for a program as powerful as Solidworks. Anyways, any help on the matter would be appreciated. Thanks.

What are your computer system specs?

Any chance you can post your file for us to try? Use the Advanced Editor link in the upper right of the dialog box.

Cheers,

Anna

  Hello Anna,
  
  Here are my computer specs:
  I also attached the file I am working with so you guys can give it a try if you want to. Thank you for replying Anna.

    Not sure if the results are good. But I had no problem fitting the spline. Took only a few seconds.

      I am glad you were able to get it to work Anna. Did you use the convert entities tool, then the fit spline? I am still having trouble with it..but I did manage to find a make shift solution. Instead of making a fit spline from the whole thing, I made smaller, open splines right next to each other. It isn't one whole one, but at least I have it better organized. Thanks for the help.

        Yes, convert entity, then fit spline.
        
        The two sets of sketch data are in the sketch I beleive.

Hi Christopher,

Yes, I've seen this if you are converting a set of splines with many, many poiints - which is probably the case by what I see from your image. A few things you can do to speed it up: A) turn off constrainted and make "unconstrained (if it doesn't matter - which when transferring imported logo it doesn't) B) Make sure what you have imported isn't uneccessarily heavy - In the case of DXF, a lot of time it comes in as small poly arcs instead of true splines - which will case you headaches beyond fit spline. If your art came from Adobe Illustrator, try getting the .ai file and importing directly or make sure you have th right settings when DXF was exported.

Regards

Mark

  Thank you for your input Mark. I am importing the logo as a dxf file from CorelDraw, and it comes in very nice and smooth. No small line segments or polylines, just splines. I don't know if this matters, but when I choose "Delete geometry", the "Constrained" option disappears. It is ok though because making multiple open fit splines will solve my problem. It will just take a couple of minutes extra, which isn't to bad. It would be interesting to get it to work though.
  
  Thanks
