Bumping my question up.
It really seems to me, that the arrow size is constant and can not be changed. Does anyone have feedback or experience with AIS_LengthDimensions?

AIS_LengthDimension Arrow Size too big
Hello, i am having a problem with arrow size of a length dimension, when my model is very small.
Consider following scenario: i create a 10x10x10 box:
BRepPrimAPI_MakeBox lShape(1, 1, 1);
Then find 2 points that i want to measure and create my length dimensions object like that:
Handle(AIS_LengthDimension) lengthLabel = new AIS_LengthDimension(beginPoint, endPoint, gp_Pln(beginPoint, gp_Dir(0,0,1)));
_AISContext()->Display(lengthLabel);
ArrowTailSize: 6
Length: 6
DisplayUnits: m
Neither of the parameters that i change changes the displayed arrow size.
It looks ugly and too big (see atached file).
Do any of you have a idea how can i change the size of displayed arrows?

Bumping my question again. Any ideas? Please?
Hi Author,
I think you can use Prs3d_DimensionAspect and Prs3d_ArrowAspect to do some customization.
Handle(Prs3d_Drawer) hDrawer = m_hAISContext->DefaultDrawer();
Handle(Prs3d_DimensionAspect) hDimensionAspect = hDrawer->DimensionAspect();
Handle(Prs3d_ArrowAspect) hArrowAspect = hDimensionAspect->ArrowAspect();
Hope it helps!

Thank you very much. For future reference - there are similar methods on the AIS_LengthDimension object, but they DO NOT WORK. Maybe your answer will save someone else time when they are faced with a similar problem.
