Rhino 8 Layout Guide: Creating Scaled Sheets and Detail Views

This guide is based on McNeel’s official Rhino 8 documentation for Layout and Detail tools. In Rhino 8, Layout is used to arrange one or more model views on a sheet-sized page and prepare annotations such as title blocks, notes, and dimensions for printing. Detail viewports added to a Layout let you arrange views of the model at different orientations and scales on the same page. The workflow below separates the roles of model space and the sheet area.

1. Create a sheet and set up the page

1. Run the Layout command in Rhino and set the options for the new sheet. You can specify the sheet name, printer, a paper size supported by the printer, and Portrait/Landscape orientation. Width and height can also be specified if needed. Paper units can be set to inches, millimeters, or centimeters; if the selected unit differs from the document’s Layout unit, it is converted.

2. Choose how many detail views to start with on the new sheet. According to the Rhino 8 documentation, the value can be between 1 and 4. A sheet with four views can start with either first-angle or third-angle projection. This sets up the initial layout; you can add more views to the sheet later with the Detail command.

3. Draw a border in the sheet area or add a title block. Place text that is not tied to the model, such as the project name, sheet number, and sheet contents, in the Layout area; annotations related to the model, such as descriptions and the title block, can also be placed on the sheet.

This distinction matters to the workflow: model views are prepared in model space, while the sheet is the presentation area for printing or exporting the drawing. Rhino’s documentation describes creating surfaces or solid models in model space with appropriate units and precision, then working with details and sheet annotations in the Layout area.

2. Add, orient, and scale detail views

1. Use the Detail command to add a detail view to the sheet. With the Add option, draw a rectangle; with the Center option, create one from its center. Detail views in Rhino Layout are rectangular.

2. Double-click a detail view to activate it. In the active view, you can adjust the model display, then double-click another part of the screen to return to the sheet area. For overlapping details, double-clicking near the center of the relevant view can help activate the correct one.

3. Set the view direction with the Projection option in the Detail command: Top, Bottom, Left, Right, Front, Back, or Perspective. Use FromDetail to create a new detail based on its relative position to an existing one. You can also create new details according to first-angle or third-angle projection conventions.

4. Set the scale value in the detail properties. Scale determines how a distance on the Layout corresponds to a distance in the model. After adjusting the view, lock the detail to prevent accidental panning or zooming; use Unlock to unlock it if needed. Locked details cannot be panned or zoomed.

3. Manage visibility, dimensions, and areas outside the sheet

Control which objects appear in a detail viewport relative to that specific detail, not the Layout as a whole. HideInDetail can hide selected objects in only the active detail or in all inactive details. ShowInDetail reveals hidden objects again; use ShowSelectedInDetail to bring back selected objects. Layer visibility can also be managed for a detail view with the HideLayersInDetail and ShowLayersInDetail commands. These tools are useful when preparing sheets that emphasize different information from the same model.

When dimensioning in Layout, pay attention to which area is being measured. According to the official documentation, objects in a detail viewport are annotated using distances in model space, whether the dimension was created inside the detail or in the Layout area. By contrast, an object directly in the sheet area is dimensioned using Layout distances. For this reason, take care not to confuse dimensions describing model geometry with dimensions for graphics drawn on the sheet.

Use the ChangeSpace command to move or copy an object between model space and the sheet area. To move from the model to Layout, select objects inside the active detail. To move from Layout to the model, select objects in the sheet area, then click the edge of the target detail; do not double-click inside the detail viewport. The command’s Copy option determines whether objects are copied.

4. Check output and avoid common mistakes

According to the Rhino documentation, whether a detail viewport border appears in print is controlled by the Print Width or No Print setting in the border’s properties. Before printing, review the detail views and their scales, title block, notes, dimensions, and visible borders together. To reuse standard title blocks in different Rhino files, you can import a Layout from another Rhino file with ImportLayout; you can also duplicate the active Layout with CopyLayout.

When you need a non-rectangular detail effect, the documented method is to mask the area with a white solid hatch placed over the details on the sheet. First, prepare the Layout and details; then draw a rectangle at the sheet edges and a closed curve in the desired shape, and use these boundaries to create a white solid hatch. If desired, draw the curve in model space and move it to Layout with ChangeSpace. The hatch cannot be placed behind the detail and remains on top in the draw order. Therefore, use Draw Order to keep text, title blocks, and dimensions on top so they do not end up behind the hatch. The documentation also recommends keeping History enabled so the hatch updates when its boundaries change.

Common mistakes

• Assuming dimensions will always be shown in sheet units; dimensions inside a detail use model distances.

• Forgetting to lock a detail after setting up the view; this can cause the view to shift or zoom accidentally while editing the sheet.

• Double-clicking inside a detail when moving from Layout to the model with ChangeSpace; select the target detail by clicking its edge.

• Trying to place a white hatch behind a detail; the hatch stays on top, so check the draw order of annotations that need to remain visible above it.

This workflow is particularly useful for architecture, interior design, and visualization teams that need to produce views and annotations at multiple scales from the same model. Layouts and detail viewports help manage sheet composition separately from model geometry; however, for accurate output, check scale, viewport locking, detail-specific visibility, and print border settings together. The commands in this guide are based on the functions described in Rhino 8’s official documentation.
