Loading Parts Faster in SOLIDWORKS Plastics – An option lets you control the loading of plastics analysis data when you open part documents. In the Settings PropertyManager, load plastics data when a .sldprt is opened is cleared by default. Saved plastics simulation data is loaded with the activation of the PlasticsManager tree. Selecting Load plastics data when .sldprt is opened results in longer loading time when opening .sldprt files with saved plastic simulation data.
