The original data of the manufacturers is based on the eCATALOG solutions technology by CADENAS ().\ The data is imported into Unity as Collada. All imported parts are still connected to the CADENAS database so that you can change later on parameters and update the part in Unity.\ parts4cad is a pure Unity Editor utility. {% hint style="warning" %} Parts4cad requires the parts4cad client software. If you use parts4cad the first time the parts4cad client will be downloaded automatically into the `StreamingAssets` folder inside of your project. {% endhint %} ## Installation and first usage {% hint style="info" %} Parts4CAD only works on Windows system. **In your project folder path no "Spaces" are allowed** Parts4CAD is already included in Starter and Professional version and does not needs to be installed separately. {% endhint %} After installing parts4cad from Unity’s Asset Store or after manual installation from an asset package you can start parts4cad by selecting `Tools > realvirtual > CADENAS parts4cad` in the main menu bar.

If you use parts4cad the first time a message will ask you to allow the download of the parts4cad client to the `StreamingAssets` folder:
