| Summary | 0033393: Mesh - Changing parameters do not appear to affect certain parts of the mesh | ||||
| Description | I'm working to reduce the file size on some by reducing mesh density, however, I find the behaviour from BRepMesh_IncrementalMesh to be quite unpredictable, more notably the parameters: -aMeshParams.DeflectionInterior -aMeshParams.AngleInterior -aMeshParams.MinSize do not seem to affect the mesh at all secondly there are some faces on the models I am using that do not apear to be affected by any of the parameters, for example I have included a photo meshed with the parameters ```aMeshParams.Deflection = 1.0``` (1mm) and ```aMeshParams.Angle = 0.5``` which results in a decent clean mesh, however the file size is still too large for my purposes as the geometry is too dense at the areas where there are bevels after this I have included a mesh generated with extreme parameters ```aMeshParams.Deflection = 2000.0``` (2m) and ``` aMeshParams.Angle = 3.1``` however this does not seem to affect the bevel on the ball valve as you can see in the third and fourth picture this does not appear to decrease the geometry located at the bevels despite all the other geometry changing? | ||||
