IES Patterns and Files in nXtRender

[Albert D Hart]

I just saw your newsletter on IES Patterns, etc. Can I use them with AutoCAD?

I am attaching a ZIP file of the 30 IES patterns.

You should be able to unzip these and use them, or any manufacturer IES files from the web with nXt Render. Here are 6 of the 30 patterns.

Here is a link to images of the 30 patterns. For many situations, one of these patterns may be ideal:

To use IES lights with nXtRender, follow these instructions:

Use the following steps to attach an IES file distribution to a light source:

• Create the light in the usual way.
• Right click on the light in the list and select Properties... from the menu
• Change the Light Pattern to Goniometry File
• Click the Browse... button and select the .ies file.
• Normally you will want to use the file to define the intensity of the source as well. Click the From File checkbox under Brightness to do this.

Can I create a new custom light fixture block that I can attach IES info from a manufacturer to?

You should be able to assign the IES light to a light in a block, save it away, and use it in other drawings.
