Relative Accuracy Problem in part model

For one of the components in an assembly is having an issue of relative accuracy.

All features of this component are not getting generated after removing further material from it. As estimation of relative accuracy is not proper.

One of the solution can be to adjust the 'min.' dimension to clear this relative accuracy.

If there can be any other solution (so that dimensions will not be altered), pls. share the details.

Regards

Prateek Agarwal.

Relative accuracy works on simple parts with a close relationship to all feature sizes. Long parts (regardless of actual size) with small features always have issues. It's meant to save file size, but I normally just set mine to an Absolute value of .0001 or so. First, you must have it enables in your config.pro:

Just to note: 0.0001 is probably overkill if you're using mm (I suspect Frank is using inches)!

0.01 mm works well for us (automotive transmission parts). Of course, if you're doing some sort of micro-engineering, you may need to set a smaller value.
