This is the new specification form for a Multi-Fixed Door. It replaces both the Multi-Fixed and Multi-Vary door type from Doorlister for Dos. It does everything they did plus a lot more.

It may be used as a Wainscot type definition that allows the left and right styles to be different widths (as do all doors now). The top and bottom rails may be different widths, allows specific (fixed) section heights for the top and / or bottom sections and allows a different number of sections (and thus mullions) for the top, bottom and mid sections. It even allows any specific section (or all) to have mullions based on an increment (i.e. every 30 inches give me another x section.

To have a specific section based on increments, set the Sections to 0 for that section and set the "If 0, New Section Every" field to the size where you want a new section added. For example, if you want a new section every 30 inches for the Middle sections then set Mid Sections to 0 and If 0, New Sect Every to 3.

You may establish a ratio between top and bottom sections by entering a fraction between 0 and 1 (like .4 for 40%). If ratios are used, then no mid sections are allowed, however you may vary the number of section across in the top verses the bottom.
