Hello,
What is the the geometric precision used in RFEM 6? I'm working on a script that exports geometry from CAD to RFEM, and I'm not sure how precise the node coordinates need to be in order to avoid disconnected geometry.
My main concern is intersection of non-orthogonal lines. To how many decimal places can I round the intersection point coordinates without changing the actual line geometry or causing connectivity problems in RFEM 6? In short to avoid getting the orange line.
Thank you.
Hi mejra,
You can check the full precision at the nodes - there should be up to 14 decimal places:
In general, you can (and sometimes need to) adjust the model tolerances in the settings to control when adjacent objects are considered connected in the calculation:

So it’s not always necessary to model with exact precision down to the last decimal place.
Also note that computers work with floating-point numbers. Rounding can be applied here if needed:
Best regards
