bonassus Posted August 21, 2018 Share Posted August 21, 2018 I'm found this point expression point("../instance1",instancepoint(),"Cd",0) to access the value of the first index of the Cd vector attribute. However i can't find any reference to this usage of the point expression in the help files. the help shows point(geometry, string attribute_name, int pointnumber) with the attrib string as the second parameter and the point as the third. When there are 4 parameters it appears that 2 and 3 are swapped. this makes sense but is this shown in the help? thanks Quote Link to comment Share on other sites More sharing options...
