Jörg 29 Report post Posted October 21, 2014 Hi together, Please find attached a very simple example where I switch between two curves to generate a surface. The switch is realized by using the advanced options of the feature definition arguments. There is an auxiliary bool argument which I use in the advanced options of curveA and curveB. Note that there is a documentation button in this dialog which directly leads you to the description of all options. The bool argument itself is hidden, see also its hidden options. Finally, an IF-statement based on this bool switches the input for an image curve. There are many possibilities to design and customize own interfaces for Features, this is only a small but maybe helpful example that introduces this topic. I attached the project file.
