Switch between Mimics and 3-matic (Mimics Innovation Suite 22.0)

Many workflows require the use of multiple tools from Mimics and 3-matic. With scripting is possible to automate such workflows and use tools from both software packages.

This tutorial shows how to continue the workflow in 3-matic while working in Mimics. The results of 3-matic are returned to Mimics and the script continues in Mimics. You can have the scripts of 3-matic and Mimics in different *.py files or in the same file. For this tutorial a single-file script approach is selected.

The Mimics project Heart.mcs from C:\MedData\DemoFiles is used. 3-matic is used for some advanced operations that are not available in Mimics, consequently there is no 3-matic project loaded.
