Loft profile setDirectionEndCondition

[Anonymous]

Hi everyone,

I've been trying to create a loft between two sketches, and I'd like to set the loft to be driven by the direction of the first spline.

I know I should be using 

returnValue = loftSection_var.setDirectionEndCondition()

but I have no idea where I should put it. I've been trying all day. I am new to this and I feel like something very basic is missing from my understanding.

Here's my code:

loft looks like this nowit should look like this

Hello,

Please take a look at the line marked as red to show how to set direction end condition.

Thanks,
