DesignModeler Scripting: Direction vector in extrude command

I want to extrude a surface body in global x direction by Designmodeler scripting. Unfortunately, the direction vector cannot be specified in the API-command:

Designmodeler Users' Guide:
Extrude(Operation, BaseObject, Direction, Extent, Depth, Extent2, Depth2, Walled, Thin1, Thin2)

However, in Designmodeler's GUI it's very easy to specify the direction vector:
Attachment 40241

Does anyone know how to solve this problem?

Hi Tobias,

I have never used it but you can give this a try.
After defining Extrude and before Regenration you mite have to add the below code.
But before you could do use that, you have to named select the 2D edge ("EDGE1") you want to use to call it in script.

Code:

ag.listview.ActivateItem("Direction Vector");

agb.ClearSelections();

ag.edgePick;

agb.AddSelect(agc.TypeEdge3d, EDGE1);

ag.listview.ItemValue = "Apply";

So basically your code should look like this:

Code:



//Define Extrude

var Extrude1 = agb.Extrude(agc.Cut, ps5.Sk5, agc.DirSymmetric,

agc.ExtentThruAll, 0.0, agc.ExtentFixed, 0.0, agc.No, 0.0, 0.0);



//Define Direction Vector

ag.listview.ActivateItem("Direction Vector");

agb.ClearSelections();

ag.edgePick;

agb.AddSelect(agc.TypeEdge3d, EDGE1);

ag.listview.ItemValue = "Apply";



//Regenerate

agb.Regen();

You can try the below mentioned code to do Named selection:

Code:

var EDGE1 = ag.m.ModelEdges(1); //you have to find out what number edge you want as your 2D edge

agb.AddSelect(agc.TypeEdge3d, Edge1);

if you want to change Direction vector you need to call that particular Edge which you want to specify in Direction Vector.

Hope it helps

Dear Kapi,

thank you for this solution. I found out that it's also possible to set the direction vector by the command
extrude_obj.SetDirection(x,y,z).

#### Code example #####
var ext1 = agb.Extrude(agc.Add, ps1.Sk1, agc.DirNormal, agc.ExtentFixed, 3.5,
agc.ExtentFixed, 0.0, agc.No, 0.0, 0.0);
ext1.SetDirection(0.5,0.5,0.5);
agb.Regen(); //To insure model validity
