HOTSPOT QUESTION

Anonymous — Mon, 18 Jul 2011 11:36:45 GMT

Hello attached is an image which best describes my situation sorry my GDL knowledge is very limited but I can still make basic parametric objects

basically i require a 3d object with a 2d drawing in a separate location, any distance from the base point of the 3d object..I need to be able to move and arrange the 2d and pull it around via a hotspot but i just don't understand the line of code i require.

so far i have tried to understand the use of hotspots2 but to no avail i have experimented with a few things but just need a nudge here is one example

ADD2 6,6
unID = 1
HOTSPOT2 0,0,unID : unID=unID+1
RECT2 0,0,B,A

Kindest regards

Dale

There are 2 ways to do this:
a) use the stretchable a/b Rectangle

try this script:

PROJECT2 3,270,2   !(Projection of the 3D-Part in the right lower corner)

HOTSPOT2 0,0
HOTSPOT2 -a,0
HOTSPOT2 -a,b
HOTSPOT2 0,b

RECT2 -a,b,-a+1,b-1   ! (2D-Rect in the upper left corner)

A and B are set to 10 meters

b) use intelligent hotspots.
example:


HOTSPOT2 sideX, -0.1, 	1, sideY, 3	!Referenz
HOTSPOT2 sideX, 0, 		2, sideY, 1+128	!Basis
HOTSPOT2 sideX, sideY, 	3, sideY, 2	!Beweger

HOTSPOT2 -0.1, 		sideY, 4, sideX, 3
HOTSPOT2 0, 		sideY, 5, sideX, 1+128
HOTSPOT2 sideX, 	sideY, 6, sideX, 2

sideX and sideY are 2 length type parameters.
They can be used to move the left upper corner.

The electrigon object found in the depository Here uses the second method to do just what you are wanting since there was a need to move the 2D symbol separately from the placement of the object in 3D.

Take a look at the object to see how it was accomplished.

wow thanks heaps Joachim Suehlo and Erich. The intelligent hotspot sample Joachim was what i was after.. i have no idea how it works by looking at it. i wish i did, but it has solved a problem thank you very much

Have a look at the "Rabbit Hole" link in Erich's signature.
It is explained very well there in his blog how the hotspots work.
