Hi,

I am trying to build a model with a tolerance of 1 mm (building).

This model is exported to a another tool for finite elements meshing and calculations.

My main concern is to make sure that two elements that should be “connected” on a point or an edge are indeed.

The model are mostly made of linear 1D and 2D plane elements (no circles or curved elements).

I obtain things as the following:

It shows that with a tolerance of 0.001 m, the two edges (connected at 90°) are distant from 0.0000173 m

I am wondering :

1- why is it possible to have distances lower than the tolerance (which are not an intersection) for such elements, knowing that they are perpendicular planes (could be the same question for planar cases) ?

2- is there a solution, for elements that could theoretically be in that situation (ex. the exact position of an intersection of two elements not being co-planar or perpendicular), to properly connect edged/corners of such elements within the imposed tolerance ?

Many thanks !
