Can I convert a PDF to a CAD file format?

There is software available that can convert a PDF file to a DXF file format. There are limitations to all PDF to DXF conversion software. The PDF file may need to be a high-quality vector based PDF file to generate a clean DXF file. When the DXF file is imported into Visual the drawing will need to be scaled to the appropriate dimensions.

You can perform an internet search on 'PDF to DXF' to find conversion software. The Visual Support Center uses the Aide PDF to DXF Converter, you can download a trial version at www.aidecad.com.

Photopic and Scotopic Lumens - 2: A Bit of History
Lessons in Lighting by David DiLaura

Is there a good reason to consider the historical development of our current definition of the lumen? The answer is not obvious. In our hurtling, warp-speed, instant-this and instant-that world, it may seem that we have no time for history; it is all we can do to come to grips with the latest whiz-bangery. And in the press of commerce we may come to agree with Henry Ford when he famously said “History is bunk.” But the Spanish-born American philosopher George Santayana (1853-1952) warned us: “Those who cannot remember the past are condemned to repeat it.” We can be more specific: A clear idea of where the lumen comes from and how it came to be defined deepens our understanding of this fundamental concept, helps us use it correctly, protects us from fads and humbug, gives us the hard-won clarity achieved by early workers in this field, and generates a healthy skepticism about the universal use of the lumen. Thus, a bit of history.
