I have seen this a couple of times now, would like to know if other SolidWorks users see the same.
If I only change the direction of the cut extrude, the volume of the part changes from 66.90606444 to 66.90604322 cm³ and back. I know it's a small difference, but still...
Have to check on SolidWorks 2003 version, that was making the best calculations ever.
Hi,
and when you change the cut to blind 100mm or up to (outer) surface, you get more *other* results…
Go to evaluation tab and start measure. klick units / precision and you'll find the possibility to change the calculation precision:
(sry for screenshot using German)
Yes, put the precision up to max, difference gets less.
However, I see this lack of precision getting much larger in more difficult parts. That is why I showed a pure simple part with this result. Still don't understand why directions of cut and length of cut have effect on accuracy.
In the old days I used SolidWorks to create impellers with complicated sketches. In SolidWorks 2005 this gave very accurate results. From SolidWorks 2010 up to now there has something changed in the calculations.
What measuring instrument will you use to measure that in the real world?
