Arrow heads

SeaGeoff — Tue, 20 Dec 2005 08:09:21 GMT

Hi folks,
is there any way to access the default ArchiCAD arrow heads when scripting 2D lines. I want to make a simple "ALIGN" object and am wondering if I need to script the arrow heads as polygons. Thanks in advance.

You will have to to to it by polygons. There is no access to the arrow head settings.

Thank you my friend. I was afraid of that. Oh well, not so hard I guess as long as I don't feel the need to offer more than one or two.

Since you are working with AC9 you can use DEFINE SOLID_FILL to be shure to get a solid arrow head:

filltype=MAX(IND(FILL,"Solid"),IND(FILL,"Solid Fill"))
IF filltype=0 THEN
  DEFINE SOLID_FILL "Solid"
  filltype=IND(FILL,"Solid")
  ENDIF

FILL "SOLID"
d=0.02
POLY2 3,2+4, -d/6,0,d/6,0,0,d

Yes, scripting the arrow heads is easy enough as long as you don’t need to offer the entire selection available with lines and labels. My object is built and performing well, just having some hotspot editing problems, which I will post separately. Thanks again.

Sorry. My script has a tiny bug:

FILL filltype

(instead of FILL "Solid") is right.
