    Hi Joerg,

     

    According to the definition of the Teta-angle in the picture of the profile above, the rotation (pitch) of the blade is done at the "1/2" point, which by definition alters the rake (ZR). This is not the case when modelling in CAESES. Thats the reason for our confusion.

     

    I guess the blade profile is rotated around where the mid choord crosses the z-axis, in order to alter rake, skew and pitch independantly?

    Hi,

     

    In order to understand your definition of pitch, skew and rake I have a couple of questions.

     

    In the documentation there is a profile and a picture showing the definitions, although its slightly confusing since the (by the look of it) the pitch definition is defined as the blade profile is  rotating around max thickness when picth is altered.

     

    If that is the case then rake would be influenced and this is not the case when you model the blade by the curves in CAESES. 

     

    Can you point out what the tho points in that picture represents, one should be the generator line and the other max thickness, but which is which?

    Hi

     

    I've tried to understand how to do this the most straight forward way but I cannot find the suitable functions for it.

    I want to do a generic curve with x and y inputs. And the x and y needs to be functions of a number of predefined B-spline curves.

    So if I for instance would like to set x as (A^2 * sin B ), where A and B are predefined B-spline curves in my project. How do I do this the most effective way by feature programming?

    Is there some tutorial on how to use the 2d-window for drawings and 2d-representation of a blade? Or for that matter showing any curves in the 2d-window.

     

    I can not find any way on how to show curves from an object in that view, I managed to drag and drop a curve but it will jsut show up as a line without any way of giving coordinates. 

    I dont find any way of giving what plane I want to see either.

     

    How do I use the 2d window at all?

    Hi and thank you guys for a good training session!

     

    I've got two questions:

     

    Firstly, is there any way de-coupling the various windows from the framework in order (for instance) to have the 3d-view in a separate monitor?

     

    Secondly, when designin a blade, the 2d blade features are still very important in order to relate it to old designs and in order to be able to do a 2d-drawing. What tools and functions are the best to relate the 3d generic blade to a 2d-plane (i.e developed view)

     

    Regards

    Daniel
