Overview

QtDraw is 3D drawing tool for molecules and crystals based on PyVista and PySide6. The main window and available objects looks like the following.

All objects can be modified by GUI in the Dataset window.

All objectes are located at the position + cell in the fractional coordinate of the crystal system with the origin, which allows us to repeat the drawn objects just by pushing repeat button. By non-repeat button, the repeated objects can be converted to those at the same position with the home cell, i.e., cell=[0,0,0].

By installing the Pyhton package, MultiPie, which provides the various crystallographic symmetry operations and symmetry-adapted basis construction, object drawing in QtDraw is also associated by the symmetry operation and symmetry-adapted basis. To use this functionality, after installing MultiPie, push MultiPie button in the bottom right. The additional window for MultiPie plug-in is shown as below.
