SolidWorks Scaling

[kgaydosh]

We design and manufacture HDPE containers and blow molds.
We create the product model for the customer then we create a scaled up model for the mold designers.
We have been using SW 2003 for a couple of years with no scaling inssues, but we have switched to SW2004 about a month ago and have ran into two different models with differnt scaling issues.
My questions is has anyone else had problems scaling, if so have you found anything that my fix this problem.


Thanks

Please be more pecific.
What exactly are the issues? Overscaling, Underscaling, Inconsistent, Doesn't happen, ?????

Dosent happen,This is the error we are getting,
"Scale1: The scale operation failed to complete as it would have resulted in inconsistent geometry. Try using a different scale value."
We are using a uniform scaling of 1.018"/" about the origin.
I have tried different values with no success.

The error message makes it sound like the scaling is causing a portion of the parts geometry to be invalidated. Does the part have very small sections of lines or radii? Or maybe larger tangential radii with one or more "fixed" points. The scaling may be eliminating or reversing those sections.

kgaydosh,
What I suggest in a case like this, is to open up an old mold that you knew worked ok in a previous version of SolidWorks. Redo the scale feature. Does it still work? If it works ok, then you may know it is your new mold.

Kevin,

I have run into this as well. What we found out was that there were edges on the model that were not "perfectly" stitched together. We have this in Pro/E and SolidWorks.

Try this. Save your model as an .X_T or .STP then bring it back into SolidWorks. After you bring it back in, run the diagnosis on it and look for surface problems.

tbeck11,

That's what I was just about to suggest. We've had the same problem before and the parasolid export/import seems to do the trick. I think the part tends to rebuild during the scaling operation, and a particular feature gets in the way--just a theory.

Besides, the parasolid is a nice, small file that works great when doing more complex cavity operations. This gets important with complex geometry and parting lines, pulls, etc. Although I would expect a blow-mold to be relatively straight-forward.
