Was Stretchy, Now It's Not

[Anonymous]

In an earlier version of the code shown below, you could stretch length A using one or the other of the hotspots shown in red. In the process of making a few changes, this functionality went away. I have tried everything I can think of to get it back. I didn't program this behavior in the first place, it just worked. Help!

100: !!DEFINE TEXT STYLE
DEFINE STYLE "AC_STYLE_1" pTextFont, pTextSize / 2.54, 5, 0

Matthew stated the way it works. When you grab any hotspot, ArchiCAD checks whether there is any hotspots in the Object that is at a distance of A in the horizontal direction. If there is any, the object will be stretchable in the horizontal direction.
Similarly, it checks whether there is any hotspots in the Object that is at a distance of B in the vertical direction. If there is any, the object will be stretchable in the vertical direction.

If you add another hotspot:

rect2 0,0,a,b
rect2 0,0,a*.5,b*.5
hotspot2 0,0
hotspot2 a*.5,b*.5
hotspot2 a,b
hotspot2 -a*.5,-b*.5


then the hotspot at a*.5,b*.5 will also be stretchable in both directions.

But if you do the the following:

rect2 0,0,a,b
rect2 0,0,a*.5,b*.5
hotspot2 0,0
hotspot2 a*.5,b*.5
hotspot2 a,b
hotspot2 -a*.5,b*.5


the hotspot at a*.5,b*.5 will be stretchable only in the horizontal direction as there is another hotspot that is at a distance of A in the horizontal direction (-a*.5,b*.5), but there is no other hotspot that is at a distance of B in the vertical direction.

Thanks for the information on adding the additional hotspot. I was unaware of the effect it would have. So, basically, in order to have multiple strechable points based on "A", it requires more than 2 hotspots.

I have been using the diamond spots for strechable points, but this may be a simpler approach for some of the objects I'm working with.
