Multi-section solid 1

[thenaughtyatom]

Hi all. I have a part for a school project and I have been struggling with it for the past couple of days. I read a lot about multi-section solids and finally made what is shown in the picture. It is supposed to be a blade for a turbine. All goes well, until I try to create the solid. I select the airfoil-looking closed curves as my sections and the two side lines as the guides. However, when I click on Preview it gives me the error in the second image. I read on some other forums that if I reverse the direction of the closing points' arrow it will work, however it didn't. I tried moving around the closing points, selecting the elements in different order, but none of that worked. I am really desperate that I will make it, and to be honest, I spent so much time on it that starting anew just seems pointless now. Please help me since I cannot complete my project without this part.

The message says one (or both) of your guide curves don't end at the section curves. (ignore the stuff about a spine) So, you have to modify them to make them touch.

I would step back and make the Multi-Section Solid from just the two section curves, and see what that gives you. (I'm surprised you don't have more sections to define the blade?)

Then edit the solid and add the guide curves (after you verified they do end at the sections) to get the final blade shape.

Hey, jackk, thanks for the response! I zoomed in quite a lot and saw that indeed the points are not where they are supposed to be. I fixed that and created the guide curves again. However, now I get a different error. First image is how I defined the solid, and the second image is what the error is. I googled it and all I could find was to reverse the arrows of the closing points' directions. I tried that, without any luck. I also played around with the coupling method - tangency, ratio, etc. but nothing worked. I would be really happy if you had any idea how to fix this.

can you share your geometry?

That message means the Guide2 curve is too curvy and is causing the surface to buckle.

Try this: add a spine. Choose the axis that is perpendicular to both of the section planes.

[SOLVED]

I managed to solve my issue simply by playing around and reorganizing my excel file (the GSD_Point....xls). I spent some 30 mins prepping and organizing the file, so that it's easy to use for the creation of multiple sections. I then made multiple sections of increasing size and rotation (the one I need) and simply created a multi-section solid without any spines/guides - just selected all sections and voila! Thanks for all the help, and also, if someone else is having trouble with this, I would be more than happy to share my excel file with explanation on how to use it.

Thank you for all the answers and time, jackk!

Hello Thenaughtyatom,

I am doing something similar at the minute. Could you please share the xls file?

Many thanks!
