As you all (hopefully) know by now, you can set the 3D solid buffer quality in the Simulation Settings to Low, Medium and High.

The quality you will be able to use depends on your computer hardware and your demand for speed during simulation. In some situations, for example when milling small parts the High setting will not give enough resolution. Also, users with fast computers and huge amount of RAM memory will want to run a higher setting. With the new version (1.0.5.2) we have added a simulator command called $OverrideBufferQualitySetting. You can add it to the start of your program to customize your quality setting. For example, a value of 10 will give a buffer with 10 buffer points per unit. It will also slow down your simulation of course. You can play with this override setting but remember, you can easily create a memory overflow with a too high setting.

This zoomed in part was milled with the Medium setting, look at the edges of the arc and the hole.

This is the same part with $OverrideBufferQualitySetting 10.
