Can I import files from other pCon applications?

Use the pCon Exchange Container (PEC) to import products, typicals and commercial information to your current project. PEC is an exchange format that allows you to export graphic models and article data from pCon.planner and use them in pCon.roomplanner. Article hierarchies, spatial relationships and configurations are retained in pCon.roomplanner.
