Hi @GaborV_Shapr3D Welcome to the Forum, I trust that the S3D Team have warmly welcomed you
Perhaps the ‘Snapping’ problems begin where they are not expected?
Over the recent past I have attempted to bring the following to attention. It was anticipated that others would chime in with their results and hopefully prove me to be wrong. The following has been repeated very many times, the displacements recorded are remarkably similar in all of the recorded events.
Snaps are all switched on. The discrepancies are minuscule and if considered insignificant this needs to be explained.
Sketch a Circle and at least one Radial line to represent the Radius Dimension, size unimportant, but it should centre on the Junction of the X-Y-Z Axis:
Next Zoom almost fully in to the Centre of the Circle, note this will take many spreading actions to achieve the result shown. Clearly the Centre of the Circle is positioned as intended:
Next Zoom to the top of the Vertical Radius Line until the the End can be seen to overshoot the Circumference Line [shown on the right].
Then investigate the point [marked with a vertical line at where I consider the Maximum Diameter is positioned, i.e., 0.042mm to the left of the centre]:
Further Zooming in to the above point indicates the Maximum Diameter of the Circle is less than expected, i.e., the difference between the ‘peak’ of the Circumference Line and the Grid Line, the latter being also the End Point of the Radius Line]:
Regarding Alignment may I suggest you search the Forum because there are several Threads covering this subject. I do not have any experience with SolidWorks and hope other Members will chime in.
Very much looking forward to the outcome of your task.
