Hi everyone.

 

I need to import two blade profiles into DesignModeler for create the 3d shape of my blade. I have hub profile, and tip profile. I have uploaded in a correct way the two profiles using the feature "3D line". 

 

Then, for recreate the 3D shape, I need to make the "Skin/Loft" command. But the command does not work, and has the following error 

Error: Solid operation failed
Context: Skin/Loft Feature Skin1

Anyone of you can help me?

 

Thanks in advance

using skin/loft on edges, you will get a surface. 

please check help document for details of skin/loft. 

you can also see many videos on youtube. 

you can also explore spaceclaim. you can use blend option in spaceclaim.

Hi kkanade,

 

thanks for your answer. But, reading your message, I don't understand how to solve my problem, simply because the surface between the two profiles is exactly what I want to obtain.

 

What is your suggestion? Do you think that the "Skin/Loft" command is correct for have a surface between the two 3D lines?

 

Thanks in Advance

Do these curve form a closed loop?

If so, you can split the curves and then try skin/loft.

Dear kkanade,

 

my two curves are closed. So, I used your suggested command "Split edges" in Concept window. I divided each curve, in the photo above, in two parts. So, in the end, I have four parts, two in the lower curve and two in the upper one. 

 

Then, I performed the skin/loft operation on two of the four parts (one piece of the lower curve and the other of the upper one) and works well (so, with this operations, one of the two blade wall is created). But, when I perform the second skin/loft operation on the other two parts (for have the second blade wall), the operations fails, and returns a specific error:

Error: Feature has self-intersecting geometry
Context: Geometry Engine, while generating Feature Skin9

Warning: Open profiles should be used with As Thin/Surface = Yes
Context: Skin/Loft Feature Skin9

 

I remember that this error is not present in the first skin command, but in the second, when I try to make the second "blade wall". 

Maybe do I need to perform a single loft operation, in order to make the whole blade profile in a single command ? How can I do ?

 

Thanks in advance

So, I found the solution.

Simply the txt file had a too low resolution for draw a correct blade. In the end, I follow all the suggestions, and I have my blade in DesignModeler Environment.

Many thanks
