For newer versions of Blender, the real-time displaying of an objects wireframe in the 3D View is different than off-line rendering a wireframe or outline. Whilst the first aids meshing, beingness able to see structure and density at a glance whilst working, the latter can be used to make finished images look like they were rendered in SketchUp. This is done using Blenders Freestyle rendering pick.

Scene/Object Set up

To render outlines make sure at the very to the lowest degree any object to exist rendered has at least a basic node-based material assigned with a Base Color ('diffuse') set and scene appropriately lit. Equally outlines in this context are a rendering post-process a Photographic camera entity is too required, positioned relative to the indicate of view expected of terminal image output.

Design notation: rendering outlines does non specifically require complex node-based materials then a uncomplicated consignment with an (optional) lengthened colour will suffice [a] – all materials have a off-white tint by default that tin can exist inverse in the Node Editor.

Outline rendering outline can use basic materials
Rendering and outline around objects is independent of materials but objects should accept at least a basic Material assigned to be able to control some aspects of the final render, Diffuse colour in item

Enable Freestyle

To produce a SketchUp style outline render, once a Scene and objects are prepped, in Return Properties [1] click the checkbox side by side to Freestyle [2] enabling access to a set of basic options (click the arrow to expand). Hither the initial width of the outline can exist set up changing Line Thickness (1.000 px being the default, Line Thickness: ane.000 px).

Access Render properties and enable Freestyle
Outline rendering is a setting inside Return Properties [1] so access the console and click the checkbox next to Freestyle [2] enabling and revealing some bones options, Line Thickness in particular.

Render Outline

With Freestyle now enabled to return the outline printing F12 or switch to the Rendering Workspace to see the results. The Blender Render window volition open, or the Rendering viewport will update showing the resulting scene/image with objects outlined.

Press F12 to render the scene with outlines
With the scene set up and Freestyle enabled press F12 to initialise rendering and see the basic effect, an outline (black past default) effectually all objects in the scene (using a simplified, object intersection, occlusion).

Colour/Tinted Outline

For more control over rendered outlines a set of additional options are available to alter the appearance of the line. At information technology's most basic the Freestyle options available in View Layer Properties [three] allow the outlines color to be changed under Freestyle Line Style [4]. Hither accessing the Color options [5] within which the lines Base of operations Color [half dozen] can be ready clicking the color sampler and subsequence colour-wheel choice.

Design note: the backdrop and options available permit for far more than sophisticated line work to be rendered from the basics discussed higher up.

Press F12 to render the scene with outlines
To alter the outlines colour access View Layer Backdrop [3] and Freestyle Line Style [4] options to select the Colour properties and then a Base Color [6] tin be set.

Render Outline Just

To return objects with just an outline the material assigned to objects tin can be set upwardly with transparency. To add basic transparency, in Textile Properties [seven], enable Alloy Mode [8] in Settings and then change the Blastoff [nine] value attributed to the Principled BSDF node. In one case fix rendering the objects will and so show the outline just, the objects beingness transparent every bit defined past Alpha.

Blueprint note: there are several ways to prepare transparent materials so outline rendering may differ accordingly.

Setting up a basic transparent material
Transparent material with outline
Objects can be rendered in outline just if materials are set to exist transparent. In Material Properties [7], make sure Alloy Way [eight] is accordingly set and Alpha [9] adjusted equally required before (re)rendering.

Old *.alloy files

Equally a consequence of changes to Blenders rendering and fabric systems loading old or legacy *.blend files set up to produce SketchUp style outlined renders initially won't work – all the settings and options included in the file volition likely exist available just not necessarily updated for use in Blender. In this situation what's likely missing is a Freestyle Line Set, the datablock that holds all the attributes of an given outline.

Design note: when loading old *.blend files disable Load UI in Open Blender File settings lesser-left to utilize Blenders interface – for truly old files, pre Blender two.49, loading legacy interface data may cause problems so it's preferably to disable this information.

Access View Layer Backdrop [1] and in the Freestyle Line Fix subsection [2] click the + (plus) button [3] to the correct of the lineset aperture. A new entry volition appear, titled LineSet by default, accompanied past a new group of settings and options below, pressing F12 at present will include a basic outline in the render per the properties set/used.

Design note: LineSet functions in a similar manner to materials in that a Material acts as a container of sorts for associated options and settings.

Legacy .blend files will have a few missing properties
Once a LineSet has been added outlines will be rendered
For legacy SketchUp fashion rendering projects it's likely the LineSet property [ii] is not bachelor/has not been created [3] resulting in no outline during rendering. Add together one, click the + button [iii], to generate an outline.
