Looking to design your new deck during your lunch break at work? There's no better way to do it than in a SOLIDWORKS weldment part file. The one critical thing you'll need is a library of all the stock lumber profiles, so here it is:
Lumber Weldment Profile Library
Just download the ZIP file listed above and extract it into the directory you've specified for your weldment profiles (Tools > Options > System Options > File Locations > Weldment Profiles).
There's some additional information stored in a property called 'StockSize'. To take advantage of it, add a column to your cut list that's linked to this new property. Make sure to remember to save the updated lumber cut list template for future use.
