Working with SketchUp Dashes in Imported Models

In LayOut's 2D paper space, you have the most control of the quality and styling of the linework in your SketchUp model.

To get the most out of your model in LayOut, you'll want to set up scenes that capture model views and styling, and also assign tags to objects whose lines you want to style distinctly. For instance, the image below is one model viewport pointing to an orthographic scene created in SketchUp where separate tags were applied to Walls, Windows, Doors, and Furniture.



This article covers the basics of setting up a SketchUp model viewport to get the linework you want out of LayOut.

Set the viewport line scale

To control the style of linework for a model viewport inserted into SketchUp, first select an inserted SketchUp model, then open the SketchUp Model panel. (Window & SketchUp Model). This utility is where you control how your viewport displays in 2D.

To control the styling of linework in your model, start by setting the Line Scale in the Viewport section at the top of the panel.

For the entire viewport, Line Scale defines the stroke width of lines and also the dashes scale of patterns you've assigned in SketchUp. If you want to give all the lines in your viewport the same weight, you can use the stroke width dropdown.

If you want some lines to have one weight and others to have different weights, skip ahead to "Style linework for an individual tag".

By default, viewports are assigned a .5 pt stroke width and the 'auto' dash scale. If you have applied a dash pattern in SketchUp, the auto dash scale will preserve the scale of the pattern as you increase or decrease stroke width.

Choosing a rendering mode

Rendering mode is another important option in the Viewport section of the SketchUp Model panel.

LayOut has three rendering modes for viewing SketchUp models inserted into a document. Here's how each mode affect the styling of your viewport:

  • Vector and Hybrid: These modes generate crisp, vector linework from the edges in your model. Vector is ideal and efficient for clean line drawings that do not feature image textures. Hybrid renders image textures, transparency, shadows, and crisp edges, but generally takes longer to re-render as you work.
  • Raster: In this mode, lines are less crisp, but you can take advantage of additional display possibilities and rendering styles such as sketchy edge styles, back edges, fog, and depth que. Transparent faces tend to render best in Raster mode.

Style linework for an individual tag

Assigning tags to objects is what enables you to control their line styling distinctly in LayOut. Open the Tags section of the SketchUp Model panel to start styling the lines associated the each tag in your model.

To edit a tag's line style, click on the pattern next to its name. If no pattern has been assigned in SketchUp, click on the word 'Default' to pull up the tag's line styling dialog. When a tag is set to Default, the geometry on that tag will render according to the viewport Line Scale (see above).

In tag's line styling dialog, you can set the following style properties:

  • Dashes: This dropdown applies a pattern to the linework of the tag. If you assigned a dash pattern in SketchUp, you'll see it here in LayOut. If you have not assigned a pattern, you'll need to at least assign your tag a solid line pattern (the first option in the list) to edit other properties.
  • Color: Use the color picker to assign a color to tag linework.
  • Scale: Set to 'auto' by default, this scale affects the rendering of the dash pattern you've chosen. The 'auto' setting preserves the scale of the pattern as you change edge width, but you can loosen the pattern by increasing the scale, or tighten it by decreasing the scale.
  • Edge width: This field assigns a line weight to the tag linework.

When you are done changing properties, click OK to commit your changes and re-render your viewport. If you turned off Auto rendering, you'll need to click the 'Render' button at the top of the SketchUp Model panel.

Important: If you are trying to produce LayOut drawings with specific line weights to adhere to graphical standards, set the viewport line scale to 1.0. The viewport line scale acts as a multiplier to the edge width scale you set for an individual tag. For instance, if you want geometry on a Walls tag to render at .4 pt, set the viewport line scale to 1.0 pt, and the Walls tag edge width to .4 pt. Or, leave the viewport Line Scale at .5 pt, and set the Walls tag edge width to .8 pt.

How tag overrides work

When you make a change to the visibility or style settings that are also controlled in SketchUp - like shadow or fog settings, tag visibility, or line style -- that change is treated as an override on your viewport.

When you create a tag override by editing a line style, this means you can update your SketchUp model and preserve the styling change of your override. When you update a model reference, you tag styling change will persist. If you want to revert back to settings assigned in your SketchUp model, click the Reset button at the top of the Tags section in the SketchUp Model panel. Or, use the Reset all button at the very top of the panel to reset your viewport to its original state.

Explode a viewport to control individual lines

Alternatively, you can convert a SketchUp model viewport into an editable vector drawing and adjust the line widths and styles of individual edges using the Stroke settings in LayOut. To do that, follow these steps:

  • Select the viewport you want to explode.Select Vector or Hybride from the rendering mode drop-down list.
  • If the viewport needs to be re-rendered, click the Render button that appears.
  • Context-click the SketchUp viewport and select Explode. Lines from the SketchUp model viewport become vector shapes.
  • Edit the dashed lines via the Shape Style panel.
