Can you nesting multiple flat parts on a single sheet of plywood in Autodesk Fusion?
Short Answer
Yes — you can nest multiple flat parts on a single sheet of plywood in Autodesk Fusion, most commonly by arranging them in a manufacturing layout and using the Arrange command in the Manufacture workspace. This is the standard professional method for sheet optimization. Limitation: Fusion’s automatic nesting capability depends on your workspace tools and subscription level.
What You Need to Know Before
Warning: If your flat parts are not truly coplanar, fully flattened, or sized from the same material thickness, the layout can fail or produce inaccurate plywood yields. A very common mistake is arranging modeled faces instead of verified flat profiles for CNC cutting.
How to Do It
Command: Arrange
Shortcut: None by default
Quick Steps:
- Open the Manufacture workspace, then create or activate a setup for your plywood sheet and flat parts.
- Go to the appropriate toolbar panel and start Arrange, then select the part contours or bodies to place onto the sheet.
- Set the sheet size and spacing, then enable a real option such as Object Spacing before confirming the arrangement.
Variables & Settings
- Key Setting: Object Spacing — this controls the clearance between nested parts and is critical for tool diameter, hold-down safety, and cut quality on plywood sheets.
Why it Fails
- Cause 1 (Geometry): Parts are not flat, not on the same plane, or include profiles with open contours that Fusion cannot arrange correctly.
- Cause 2 (layers/Locks): Referenced or linked geometry may not be editable or selectable as expected if the source component state is restricted.
- Cause 3 (Command/Logic): The command arranges existing valid manufacturing geometry; it does not automatically repair bad sketches, flatten non-sheet parts, or replace proper nest-specific workflows.
Quick Fix & Best Practice
- Quick Fix: Project or recreate clean closed profiles, verify all parts are flat and coplanar, then rerun Arrange with proper spacing for the cutter.
- Manager’s Verdict: Use Arrange for fast, practical plywood layouts in standard Fusion workflows, but for production-grade material yield and advanced grain or quantity control, use a dedicated nesting workflow if available.
FAQ
Can Autodesk Fusion automatically optimize plywood sheet usage?
Yes, Fusion can arrange flat parts efficiently, but full nesting automation depends on the available manufacturing tools.
Can I set spacing between nested parts in Fusion?
Yes, use the Object Spacing setting during Arrange to control the gap between parts.
Is Arrange the same as true production nesting?
No, Arrange is useful for common layout work, but dedicated nesting tools are better for high-volume manufacturing optimization.
