Hi All,
If I have an expression that contains a list of polygons, is there any way I can select every second value from that expression? In the script I am working on I have an expression that contains all the polygons that represent the start and end of a concrete barrier (I am modelling pre-cast concrete barriers with gaps between them). I want to create a BSplineSurface from the polygons using "Ruled" where the even polygons are the "StartCurve" inputs and the odd polygons are the "EndCurve" inputs (so I end up with individual BSplineSurfaces for each barrier with a gap between them). At the moment the only way I can get this to work is by typing the information into the expressions for the StartCurve and EndCurve separately.
Regards,
Ryan
Hello Ryan,
As Ed has mentioned that if you are using Update 7 of OpenBuildings Designer then you can try to achieve the same using the Value & Operation node.
Please have a look at the GCT file attached.
