Today, in the case of Creo Elements Direct/Modeling, Modeling is restarted each time the WVS creates visualization data. This takes approx. 30 seconds, so that only a maximum performance of 2 - 3 parts per minute (approx. 150/h) can be achieved. In the case of Creo Parametric, the Creo process remains running and thus reaches approx. 700 visualizations/h. In addition, the termination of Modeling and WGM does not work properly. Processes remain, cannot be started anymore, interactive error messages remain etc. - all this leads to the fact that one must constantly supervise and care for the CAD Worker for Modeling. The problem multiplies because the poor performance means that up to 10 times more CAD workers have to be set up than with Creo Parametric. Today it is not possible to operate a reasonable visualization infrastructure with Creo Elements Direct/Modeling.
