Hole size
Keep hole diameters at least equal to the material thickness. Smaller holes can be cut, but they may taper or need a secondary drill or ream. FoxQuote flags holes that are too small for the material you chose.
Feature spacing
Keep holes and slots at least one material thickness from each other and from the edge, and more on thin material, so the web between them doesn't warp from heat.
Tabs and slots
Tab-and-slot features let parts self-fixture for welding. Make slots about 0.010–0.015 in wider than the tab thickness and add a small corner relief.
Etching
Part numbers, bend lines and assembly marks can be laser-etched at almost no cost. Put them on their own layer in your DXF or mention them in your notes.
Tolerances
Our standard is ±0.025 in, with ±0.010 in where the part needs it. Call out critical features on your drawing so we can hold them.
Files
Send DXF at 1:1 scale in inches or millimeters, with closed outlines and no duplicate lines. STEP and SolidWorks files work too, and FoxQuote unfolds formed parts automatically.
