Hole Measurement Problem

[ekadiroglu]

In the measurements from hole to hole in the picture below, a delta measurement appears after the comma in different axes from time to time. (0.000000000175mm)
This is especially true for threaded holes.
Anyone have an idea about it?

Thanks,

Best regards,

Hi! Inventor 3D body geometry should be accurate up to 0.00001mm. Any higher decimal places could be numerical noise. However, for precise model 0 should be 0. 0.000000000175mm does not look like a noise to me. Please share the ipt file. I would like to take a look.

Many thanks!

Has to be a modelling error unless it's a bug. 

Is your rectangle drawn square to the origin in the first place?

Hi,

I attached the file for measure problem form hole to hole with threat,

Thanks,

It's a step file so there are no threads

I measured all the holes I think and I don't see any discrepancy, even on all decimals precision.

Hi! Many thanks for sharing the file! I tried measuring the distance between two holes. I see that when two cylindrical faces are selected, the minor numerical noise can appear in one of the offset values. But, the same thing does not happen if circular edges are selected. The behavior seems to start from 2022. Attached is the same file imported to 2016 and I was not able to reproduce the behavior in 2021 and earlier releases.

I need to work with the project team to understand it better.

Thanks again!
