Library Loader Help

What is Library Loader?

Library Loader is a small application that allows you to convert downloaded ECAD Models (Schematic Symbols, PCB Footprints and 3D Models) from our website for placement in your ECAD Tool. It takes less than a minute to install.

Once the application is installed, you are just one click away from having the Symbol & PCB Footprint in your design!


ECAD Designing Made Easy

Easily access and insert the PCB Footprints, 3D Models and Symbols of our extensive product portfolio right into your ECAD tool.

Loading your first ECAD model

Once Library Loader has been installed and configured with your ECAD tool, you are now ready to load your first ECAD Model.

This can be done by opening a previously downloaded ECAD Model (by clicking "Open ECAD Model") or by clicking "Search for Parts" to find your first model from a supported website.

IMPORTANT – Check that the "Downloads Folder" is set to the directory in which files are downloaded from your web browser.

After loading an ECAD Model, Library Loader will now process the file and make the Schematic Symbols, PCB Footprints and 3D Models available for your ECAD tool.

For more detailed instructions, feel free to consult the SamacSys Library Loader Help page.
