Scaling profiles/splines
Scaling profiles/splines
(OP)
Hi everyone,
I am cading a wing that might need to be changed. Also I need to do multiple ribs so importing the profile everytime is going to be a lot of work.
What I am doing now is importing a spline and then project it on a sketch and isolate so I can turn it. But I can't find a way to have a parametable operation which I could use to do multiple sketches faster or change the chord later. I can't even understand how the scale function is working in the sketcher... I drag the second point and nothing logic is really happening... I Was thinking about selecting a point with a distance that I control with a parameter, but it seems there is no way of predicting the lenght or ratio used with this function.
Thank you for your help.

RE: Scaling profiles/splines
I imported the points with the excel file "GSD_PointSplineLoftFromExcel.xls" in C:\Program Files\Dassault Systemes\B23\win_b64\code\command.
Isolated the points.
In the Wireframe and surface design, I scalled a 1 cm profile.
The ratio I used is a parameter that has the wanted lenght for value.
Trace the spline with the points.
Done!
Thank you for your help ferdo
