Overview

Customers using AutoCAD often place most or all geometry on Layer 0 or ambiguous layer names that export directly from other modeling software. This creates confusion and inefficiency when files are used for automated layout with Dusty. Proper layer management is critical to clearly communicate design intent from VDC to the Dusty operator using the robot and iPad app.

Well-structured layers allow operators to quickly understand what is being printed, isolate a specific scope, and avoid mistakes in the field.

Symptoms / What You’ll See

• Most or all objects placed on Layer 0 (this often happens for nested blocks, binded Xrefs, Linked models exported from Revit)
• Operators are unsure what lines represent in the field
• Difficulty isolating the layout by scope or system
• Over-printing unnecessary or irrelevant information
• Increased need for field clarification or rework

How to Fix or Prevent

1. Define clear layer standards before layout prep
   • Establish layers that represent real-world building elements.
   • Rename layers to indicate what's included. E.g.: Columns / Single Finish/ Door Tags, etc.
2. Organize geometry by element type
   • Place each major building element on its own logical layer.
   • Use naming that is obvious to someone standing in the field.
3. Use the BURST command for Nested Blocks / Revit Links
   • Use the Burst command instead of using the explode command when trying to breakdown geometry into layers for Nested Blocks such as exported Linked Revit Files that come in as blocks or Xrefs that have be bound as a block.
   • BURST preserves the layer of the inserted block, allowing geometry to inherit the correct intent layer.
4. Do not use the EXPLODE command on nested blocks for Dusty prep
   • EXPLODE reverts all nested block geometry linework to Layer 0.
   • This removes intent, collapses layer structure, and creates confusion for the operator.
5. Separate existing and new construction into distinct layers
   • When drawings contain a mix of existing and new conditions, separate them clearly by layer.
   • Do not place existing and new elements on the same layer.
   • For example, existing walls should be on an existing wall layer, and new walls should be on a new wall layer.
   • Review which layers are intended for print, reference, and obstacles 
6. Verify layers before publishing to Dusty
   • Toggle layers on and off to confirm correct separation.
   • Ensure only necessary layers are visible for layout.
7. Verify layers before publishing to Dusty
   • Toggle layers on and off to confirm correct separation.
   • Ensure only necessary layers are visible for layout.
8. Educate the operator on layer intent
   • Briefly explain what each layer represents before printing.
   • Use consistent layers across floors and revisions.

Best Practices

• Separate existing and new construction using dedicated layers
• Keep layer names simple and consistent,
• Always use BURST instead of EXPLODE for nested blocks
• Align layer structure with how the field builds to improve communication and collaboration
• Remove or freeze non-essential layers before publishing
