Rhino 3D Tip: Professional Make2D Workflow for Technical 2D Documentation

Make2D converts visible 3D model geometry into clean 2D curves from a chosen viewport or projection. It is one of Rhino’s most useful commands for producing elevations, plans, sections, and fabrication-ready linework without redrawing the model manually.

Before running the command, set up the view carefully. Make2D captures what Rhino sees from the active viewport, so a correctly aligned camera is essential. Use standard orthographic views for technical drawings, or create a NamedView when you need to preserve a custom projection for future updates.

• Use Top, Front, or Right views for conventional orthographic drawings.
• Use SetView or Orient to align the model with the world axes before generating drawings.
• For isometric or presentation drawings, run Make2D from a Perspective viewport, but remember that dimensions may not represent true orthographic measurements.

Select only the objects required for the drawing, then run Make2D. In the command options, choose the projection type that matches the intended result. “Current View” is ideal for output based on the active viewport, while the standard CPlane options are useful for reliably creating plan, front, and side views.

Pay close attention to the output options:

• Maintain source layers retains the layer structure of the original model. This can be helpful in complex projects, but it may create more layers than needed for a drawing.
• Hidden lines creates separate curves for obscured edges. Place these on a dedicated layer and assign a dashed linetype for conventional drafting output.
• Tangent edges can be included when smooth transitions need to be communicated, but excluding them often produces a cleaner architectural or product-design drawing.
• Scene silhouette adds the outer profile of the model, making the result easier to read, particularly in elevation and presentation graphics.
• Group output keeps the resulting linework organized, making it easier to move or manage as one drawing set.

A practical workflow is to create a dedicated layer system before generating output. For example, prepare layers for visible edges, hidden edges, silhouettes, dimensions, hatches, and notes. After Make2D runs, move the generated curves to the appropriate layers, apply print widths, and clean up any unnecessary lines. This structure makes layout work substantially faster.

Make2D output should be treated as drawing geometry, not as a live link to the model. If the 3D model changes, delete or archive the previous result and run Make2D again. Naming output groups by view and revision—such as “Front_Elevation_R03”—helps prevent outdated linework from being used in final documentation.

For a cleaner result, inspect the model before creating the drawing. Duplicate surfaces, open polysurfaces, overlapping objects, and unnecessary construction geometry can all produce confusing curves. Commands such as SelDup, ShowEdges, and Check can help identify issues before documentation begins.

Once the 2D curves are generated, place them in a Layout detail or directly on a Layout page, add annotations, and export a PDF. This workflow combines Rhino’s accurate 3D modeling with clear technical communication. For Rhino software, training resources, and professional workflow tools, visit NOVEDGE’s Rhino collection.

Used consistently, Make2D becomes a dependable bridge between model development and production-ready documentation—saving time while keeping drawings aligned with the actual 3D design.
