This script will make arc's (arches) of any vert count and any height between edges. To use it select two edges on opposite sides of a polygon and run the script. By default it will create an arc who's height is 1/2 the distance between the center's of the opposing edges (gets a little funky if your object is wider than it is tall).
The other option is to use arguments
1. the number of segements to generate
2. the height (in meters) of your arc
i.e.: @{c:\edgetrick.pl} 10 .5 will create an arc that's 10 segments and with a height of .5 meters |
