Has the behavior for BoundsCalculator changed significantly in NetStandard? I have noticed with the same dwg that CadLib 4.0 calculates bounds differently than the NetStandard version. What can I do to get the calculator to work like it did in CadLib 4.0? I have tried multiple drawings and observed the same behavior. See details below. The numbers are rounded to the nearest whole number. You will notice the greatest deviation occurs on Corner 1 X and Corner 2 Y values. I can't figure out why it would do this.

In CadLib 4.0 it would calculate bounds as
Corner 1: 65, 4775, -8 E-12
Corner 2: 18215, 11174, 45

Same dwg in NetStandard calculates as
Corner 1: -1845, 4268, -8 E-12
Corner 2: 18214, 23434, 45

Code reads like this. Let me know if you need a drawing file. I can email it to you.

BoundsCalculator boundsCalculator = new BoundsCalculator();
boundsCalculator.GetBounds(DwgReader.Read(autoCadStream));
Bounds3D bounds = boundsCalculator.Bounds;

Is this the trial version? Since it puts extra text in, that will affect the bounds.

It is the trial version yes. So are the watermarks being added in the dwg read output? I thought it was just in the svg export. It almost seems like the watermarks are forcing the bounding box to be a square.

Yes, because the trial texts are added in a square.

Okay that makes sense. Thanks Wout!
