Lengthening a blade
Lengthening a blade
(OP)
Hey I've been having trouble figuring out what to do about a modification I need to make to a part.
It's a turbine blade that I need to lengthen the bottom of the blade without lengthening the top. Normally this would be easy as I could just go into the original loft that created it and mess around with it. However this is an imported file and I don't have access to the original.
I'm not allowed to post the file so don't ask. However I did make a terrible paint drawing to illustrate what I'm trying to do.
I've tried using a loft but I get alot of errors with self intersecting geometry and zero width geometry. I then used a loft cut to try to make a flat section so that I could then so then do a regular loft. It worked but is ugly and leads to some weird geometry that will make our job much more difficult in the future.
Is there a way I could just to tell it to only create a solid where there isn't already a solid? That would make things much much easier.

RE: Lengthening a blade
Without having the part to play with, I would suggest creating the needed wireframe shape, and then create surfaces from that.
The wireframe can be created by extending sketch geometry using the Intersection Curve tool with strategically placed planes & surfaces.
Start with the needed curve/line from tip to base, and extend the intersected curves to suit.
