Engineering Standard Library

The Engineering Standard Library is a community-maintained collection of reusable engineering assets for PermitCAD and other applications.

It exists to make modeling faster by providing drag-and-drop starter content such as:

• sketches
• finished parts
• materials
• textures

This library is meant to grow over time. Contributions are welcome, especially:

• more structural steel profiles
• more lumber sizes and species
• more fasteners and hardware
• more common construction materials
• more manufacturing materials
• more reference parts and stock shapes
• better textures with clear licensing and attribution

If you have a useful real-world material, a reusable part family, or a high-quality starter sketch, please open a pull request.

What Lives Here

The standard library currently contains four kinds of assets:

• *.sketch: reusable PermitCAD sketch/project files
• *.part: reusable PermitCAD part/project files
• *.material: engineering material definitions
• *.jpg / *.jpeg / *.png: texture assets referenced by materials or applied directly

Notes:

• sketches and parts are organized into subfolders.
• materials and textures are currently stored flat on disk.
• In the app UI, materials and textures may be grouped into logical categories such as composite, metal, plastic, wood, and other.

Contribution Guidelines

Please keep contributions:

• reusable
• clearly named
• technically accurate
• easy to import
• safe to redistribute

Please prefer real engineering values and cite sources whenever possible.

For materials, the best submissions include:

• a clear material name
• a short description
• units for each property
• a source for each property when available
• an appropriate texture if one exists

For parts and sketches, the best submissions include:

• a clean file name
• one intended asset per file
• a correct active sketch index
• valid geometry that imports without errors
• a material assignment when appropriate

Naming Conventions

Use lowercase ASCII file names with underscores.

Good examples:

• structural_steel_a36_.material
• wood_pine.jpg
• imperial_hex_050in_13unc_L4p00in.part
• W10x22_40ft.sketch
• lumber_2x4_L096in.part

Try to include enough detail in the file name to identify the asset:

• family or type
• key size
• length
