For automatic scrap join algorithm. But you may join any kind of lines at any line points - typically wall to corner of block
It's worth noting that there are two different ways of making a wall line invisible in Therion, which are treated differently by the automatic scrap join algorithm: line wall -subtype invisible The wall line is not displayed, and will be ignored by the scrap join algorithm. lne wall -visibility off The wall line is not displayed, but can be used by the scrap join algorithm when it chooses which points to join. This caused me a fair amount of confusion until I figured it out! Duncan.
