Q: How do I change the Units for the design file?

A: The units can be changed from the Configuration window. Open the Configuration window by selecting Configuration... from the File pull down menu. Once the Configuration window opens, select the Program tab and change the System Units.

Q: How do I change the configuration settings?

A: Go to File | Configuration on the main menu.

Q: Where do I go to set the font and page size?

A: Go to File | Configuration | Output | Page Font.

Q: What Photometric files are supported by Lumen Micro?

A: IES LM-63-95, CIBSE TM14 1988, EULUMDAT, CIE, and LTL-I.

Q: Why do we recommend Windows NT4 or Windows 2000 over Windows 9x?

A: Lumen Micro is designed to run on Windows 95, 98, NT, 2000, and Me. However, our experience has been that NT and 2000 are better suited for technical software, processor intense programs, and multitasking between these high-end programs because they help to provide speed and stability.

Q: The + and - buttons do not work when I want to zoom in Lumen Micro.

A: Go to File | Configuration | CAD | Zoom Increment. Set this to a number between 0 and 1. 1 will not zoom, 0.5 will zoom to half of the previous view (2x magnification), and 0.1 will zoom to one-tenth the view (10x magnification).

Q: How do I scale my DXF/DWG import?

A: Use the following steps:

1. Go to File | Import DXF/DWG and open up the drawing, but stay in the Import Screen (do not click OK to import the drawing into Lumen Micro's CAD view).
2. Zoom in (using the W button) on a part of the drawing you know a dimension (the width of a single parking space, for example). Note this as your "Needed Distance". Move your cursor between the two points, noting the difference in the X and/or Y coordinates displayed at the bottom of the window. Note this as your "Measured Distance".
3. Perform a simple division calculation: Divide " Needed Distance" by "Measured Distance". This is your scaling factor. Enter this number in the scale by text box. Quite often, this number is 3.28, 1/3.28, 12, or 1 ½ (Meters to feet, or feet to inches).
4. Once you enter a new scaling factor, you may have zoomed into the DWG to far to see anything, so click on the E button (Zoom extents). Zoom in again on your known object and re-measure it. It should be correct now. If not, repeat steps two and three.
5. Click OK and your drawing should be imported at the correct scale.

Note: Lumen Micro only operates in feet and meters.

Q: I am having trouble importing DXF/DWG files into Lumen Micro.

A: There are several reasons that may cause Lumen Micro to have trouble importing or exporting DXF/DWG files.

1. External references: Lumen Micro's DXF/DWG import/export functionality does not support external references or proxy objects that are contained within other drawing files. The drawing file imported into Lumen Micro to be used for a background should contain all of the active elements in one file.
2. Unexploded blocks containing elements from several layers: Lumen Micro's layering system needs to assign each element to a single layer and a single color. If a CAD file has blocks that combine elements from different layers, and these layers have different colors, Lumen Micro may not be able to import or export them correctly. Before importing this CAD background to Lumen Micro, all elements should be selected and exploded.
3. Attributes: Lumen Micro's DXF/DWG import/export functionality does not support attributes. If your CAD background contains attributes, turn these attributes off before importing this file to Lumen Micro. For example, in AutoCAD 2000, go to View | Display | Attribute Display | Off.

If you are still having problems importing or exporting a DXF/DWG file, please contact Lighting Technologies support.

Q: Why can't I print or save information in Lumen Micro? The program says these options are not available in the Demonstration Version, but I purchased the Full Version.

A: The problem is the result of accessing a Simply Lighting program from Lumen Micro using the Assist menu. To reset the licensing for the program, exit Lumen Micro, then start the program again. Re-booting your computer system is not necessary.

Q: How do I add external photometric files to the Database?

A: Photometric files can be stored and classified in the Folders. The Database is a closed system and photometric information cannot be added by outside sources, except through LTI. For more information regarding the addition of photometric information to the Database, please contact LTI.
