I'm creating a model in which I use an extruded spline for my cable connections. The problem is that the file size is getting enormous to the size of 35MB+.

I was working on project prior to this model that is very similar. I took the same approach when crating my cables with an extruded spline. The odd thing is that the files size of the older job was a fraction of the new job. What could be causing the new spline solid to be exponentially bigger than before?

Thanks

How many grips on the spline?

Well, that's interesting as well.

I tried to attach an extruded example but the file was too large .

What I did was create extruded a spline in the current drawing, then wblock'ed it into its own drawing....5MB+.

So I cut and pasted the exact same spline into a new drawing, extruded it the exact same way, then saved it...100KB.

It's a setting I'm overlooking.  Turning SOLIDHIST off and purging gave results that aren't really effective...maybe a 100-200KB difference.

I'm a little confused.

So I'm creating the cable in a different drawing and pasting them into the current drawing as a work around.  Kinda stinks.

Thanks

Sometimes the extrusion take 1 sec.  The extrusions that take 3+ seconds are the objects that end up being large files.

Could it have anything to do with the UCS?

Attached is an example of a "large file" spline that hasn't been extruded yet.  This particular entity takes  me about 6s to extrude.

Thanks

Sorry for swamping the topic, but here is a perfect example.  The green spline takes much longer than the blue to extrude.
