Creating 2D Drafting from 3D Models
Learn how 3D and hybrid models become readable 2D construction documents through viewports, render modes, sections, details, annotations, and publishing.
What to notice
A 3D model becomes documentation only when viewports translate it into readable hierarchy: plan, elevation, section, detail, dimension, and line weight.
The workflow begins with a model, but the page is really about translation. Hidden line, Renderworks styles, viewports, section cuts, and detail enlargements determine how the model becomes readable as drafting.
The workflow is especially useful because it shows several levels of representation: a plan or elevation view, a section cut, and a scaled detail.
The workflow
Translate: Use viewports to convert model information
The model stays live while the viewport controls how it reads as 2D drafting.
A viewport is a translation layer between model and documentation.
Render: Choose a render mode for line clarity
Wireframe, Hidden Line, and Renderworks styles each reveal different information.
Drafting output needs line hierarchy, not just a rendered viewport.
Detail: Use sections and details to control scale
Section and detail viewports let the drawing zoom into construction moments without redrawing the model.
Scale becomes part of the explanation.
Viewport render choices
Modes: Viewport render choices
Choose Wireframe, Hidden Line, or Renderworks-based output based on what the drawing needs to communicate.
Wireframe shows too much.
Hidden Line clarifies edges.
Renderworks can add tone and surface hierarchy.
Section: Cut line and detail scale
Use section and detail viewports to explain construction instead of redrawing it.
Place cut line.
Set view direction.
Enlarge detail where needed.
One guiding idea
A model is not documentation until a viewport decides how it should be read.
01 The model is source material
A 3D model can contain a lot of information, but documentation requires selection and hierarchy. The model has to be translated into views that a fabricator, director, or collaborator can read.
Viewports make that possible because they keep the model connected while allowing the sheet to control crop, scale, render mode, and annotation.
02 Render style affects drafting clarity
A viewport render mode decides whether the drawing emphasizes edges, surfaces, texture, or linework.
For construction documentation, the goal is not simply realism. The goal is a readable hierarchy of lines and forms.
03 Sections and details create hierarchy
Sections reveal construction relationships that a plan or elevation cannot show clearly. Details enlarge specific conditions so they can be understood at a larger scale.
Together, they turn the model into a set of coordinated drawings rather than a single static view.

Custom Renderworks style settings are file-specific.
None class usage for detail circles is workflow-specific.
