Creating Render Presets
Learn how to create render presets in AutoCAD 2018. Get quick and easy video tutorials on rendering and creating render presets by AutoCAD experts.

A render preset is a collection of rendering settings. A drawing can contain two types of render presets: standard and custom. AutoCAD comes with six standard render presets: Low, Medium, High, Coffee-Break Quality, Lunch Quality, and Overnight Quality. Each applies a specific set of rendering settings. Standard rendering presets cannot be modified, but are available in each opened drawing. Custom render presets can be modified and removed from a drawing, but are available only in the drawing in which they were defined. If you create and save custom render presets in a template file, however, those custom presets will be available in any drawing you create based on that template.

On the Visualize ribbon, in the Render panel, expand the Render Presets split button. Any custom render presets appear near the top of the drop-down and standard render presets are listed near the bottom.

When you pause the cursor over a preset, a tooltip displays information about that preset. For example, when you hover over the Low preset, the tooltip indicates that this preset applies 1 rendering level. And when you hover over the Lunch Quality preset, the tooltip indicates that the program will render for 60 minutes.

To define a custom preset, click Manage Render Presets… to open the Render Presets Manager palette. Note that you can also toggle the display of this palette by clicking the Render Presets Manager dialog box launcher on the Render panel.

You can use the controls in the Render Presets Manager palette to specify the primary settings used when rendering. For example, in the Render In drop-down, you can specify whether to render to the Render window, the current viewport, or to render a specified area in the current viewport. This is the same as the Render In control in the Render panel on the ribbon.

Similarly, the Render Size drop-down lets you specify the output size and resolution for the rendered image. The sizes listed here are the same as those displayed when you expand the Render to Size drop-down in the ribbon. You can even use this tool to access the Render to Size Output Settings dialog.

And in the Current Preset drop-down, you can choose the render preset to use when rendering the view or area.

Since this is a palette, it behaves like any other palette in AutoCAD, so it can be moved, resized, docked, floated, or anchored, and it can be locked using the Lock UI tool. After adjusting settings in the palette, you can click the Render button in the palette to create a rendering. This is the same as clicking the Render to Size button in the ribbon.

Note that to the right of the Current Preset drop-down are two buttons: Create Copy and Delete. Create Copy duplicates the current preset, while Delete removes the current preset. You cannot delete any of the six predefined presets that come with the program. But you can use the Create Copy tool to duplicate a preset and then use that copy as the basis for defining a custom render preset.

For example, in the Current Preset drop-down, choose Medium. Then, click Create Copy. The program immediately creates a copy of that preset and names it “Medium – Copy 1.” Under Preset Info, click in the Name field and change the name to “My 1 minute render “. You can also enter a description. Click in the Description and change the information here to “Render for 1 minute “.

Under Render Duration, you can specify the length of time or number of levels the renderer iterates to create the final rendered output. There are three choices:

  • Until Satisfactory renders until you cancel the rendering process.
  • Render By Level lets you specify the number of levels, or iterations, the rendering engine performs to create the rendered image.
  • Render By Time lets you specify the number of minutes the rendering engine uses to iteratively refine the rendered image.

Select Render By Time and then specify a value of 1.

Lastly, under Lights and Materials, you can control the accuracy of the lighting and material calculations used for the rendered image, and there are three choices:

  • Low uses a simplified lighting model and produces the fastest and least realistic rendering. Global illumination, reflection, and refraction are turned off.
  • Draft uses a basic lighting model and provides a balance between performance and realism. Global illumination is turned on, while reflection and refraction are turned off.
  • High uses the most advanced lighting model. Global illumination, reflection, and refraction are all turned on. Although slower, it produces the most realistic renderings.

Choose Draft and then click the Render button.

The program immediately begins to render the image. In the Render window, you can see the rendering take shape and watch the progress meter. Since you are using a custom render preset that will render for one minute, the rendering takes exactly 1 minute to complete.
