PartDesign Preferences/hr

Introduction
The PartDesign Workbench and the  Part Workbench use the same preferences. They can be found in the Part design section of the Preferences editor. This section will only be available if one of the workbenches has been loaded in the current FreeCAD session.

Available preferences
There are three tabs: General, Shape view, and Shape appearance.

Shape view
On the Shape view tab you can specify the following:



Shape appearance
On the Shape appearance tab you can specify the following:



Tesselation
In order to display an object efficiently its surface is tesselated, i.e. it is displayed with some small deviations from it real surface. This applies not only to PartDesign models, but also to other objects in FreeCAD.

There is a lower limit for the tesselation of 0.01%. If you really want to spend the additional time you can reduce the lower limit even further by opening the menu This opens the parameter editor where you navigate to.

Right click on Mesh deviation choose in the context menu Change value. Set the value to the minimum tesselation of your choice. Please keep in mind that the value is in %, i.e. for a value of 0.005% you have to enter "0.00005". The smallest value possible is 1e-7. Note: In the preferences menu you will still see 0.01% even if you set a lower value.
