ArchiCAD Tutorial | Make 2D Symbols Parametric - Simple GDL Editing (part 2 of 3)

This ArchiCAD training is the second in a three part series on creating custom objects for the ArchiCAD library. It is an excerpt from my comprehensive Best Practices Course ArchiCAD training - http://www.acbestpractices.com. In this 15 minute video, we look at how to make a 2D symbol more flexible by adding a parameter to control the size of the text and doing some simple editing of the GDL script. The result is a symbol that can be used with different font sizes depending on the context. The text size is specified within the GDL script in units of millimeters. The common standard (in the U.S. and some other parts of the world) is to specify font sizes in points. Here's how you can convert points to mm: There are 72 points in an inch 25.4 mm = 1 inch Example: 7 point text = 7/72 inch = 7/72 * 25.4 mm = 2.47 (mm) Formula: text size in mm = (text size in points) / 72 * 25.4 A variation of the 2D symbol is created with two lines of text. The break between the lines is caused by hitting the Return or Enter key on the keyboard, which actually creates a "paragraph break". When the new object is saved, you will see that each "line" of text is actually a separate paragraph within the GDL script. Separate parameters can be set up for each line (paragraph) of text, as well as for the text size in mm (or in points, as long as the script is set up with the formula above). Note that each text parameter (each line or paragraph) may be up to 256 characters in length -- which should be more than enough for basic 2D symbols.
