Orthogonal Render

The Orthogonal Render panel (VIEW3D_PT_orthogonal_render) automates the production of six orthographic views (Front, Back, Left, Right, Top, Bottom) of a selected mesh, with resolution rules driven by the object’s real-world size, and assembles the renders into a printable SVG sheet template.

This page is the parameter and operator reference for the panel.

Source: orthogonal_render.py. Sidebar tab: 3DSC. Default state: collapsed (DEFAULT_CLOSED).

Size categories

Objects are bucketed by their longest dimension. Each bucket has a configurable cutoff (in metres) and a target render resolution (in pixels).

Small (≤) / Small resolution

Default cutoff 0.5 m. Default resolution: configured per project.

Medium (≤) / Medium resolution

Default cutoff 1.0 m.

Large (≤) / Large resolution

Default cutoff 2.0 m.

X-Large resolution

Used when the object’s longest dimension exceeds Large.

The four resolution scene properties registered are ortho_render_small_resolution, ..._medium_..., ..._large_..., ..._xlarge_....

Output settings

Output

Folder where the six PNG renders and the final SVG are saved. The panel refuses to render until the .blend file has been saved (PNGs are written next to the blend).

SVG layout

Template

Selects the SVG template family used to compose the printable sheet. Two families are supported in code (FIXED_SHEET and FIXED_SCALE); the panel exposes them via scene.ortho_template_family.

  • FIXED_SHEET — renders at the resolution required to fill the sheet at a virtual 1:10 zoom level.

  • FIXED_SCALE — renders at the resolution required to print at the declared scale and DPI.

Operators

object.setup_orthogonal_render — Setup

Creates the OrthoRenderCamera and lighting rig sized to the active object’s bounding box.

render.orthogonal_views — Render

Renders all six orthographic views to the chosen output folder.

render.create_orthogonal_svg — Create SVG

Composes the rendered views into an SVG sheet using the selected template. Enabled only when the template is installed, the blend is saved, and at least one render is present.

render.open_templates_folder — Open Templates Folder

Opens the on-disk folder containing the SVG templates so they can be added or replaced.

Typical workflow

  1. Save the .blend file.

  2. Select the mesh to render.

  3. Adjust Size cutoffs and Resolution settings if needed.

  4. Press Setup — this creates the camera rig.

  5. Press Render — six PNGs are produced.

  6. Choose a Template and press Create SVG.

Remember

Resolutions are independent per size bucket. Tune them once per project so that small artefacts and large monuments share a coherent visual scale across the report.
