Lofting

price_cobb

He team supreme, been a while that I've used loft and gosh knows I was most likely lofting something dead simple so may be some of my issue.

Anyway, I've shared this with OnShape as well as here is the link https://cad.onshape.com/documents/78744784a918d7fe6bc36cce/w/be7ce1f83de61adbb06151d2/e/870df87dec6337d120b71ab8?renderMode=0&uiState=6814ce13ddcf9a7afd7c8cf9

When you get there you can see which tab this picture is from at the bottom of this picture.

Im trying to build a part that lives in an area I can't get to so there have been no measures, but lots of trial and error and I'm almost there. However I'd like to "gussy it up" a bit, by filling in the area from the blue line to the edge of the grey face that is 90degrees to the blue lines. Make sense? I want this to become a more rounded bulbous end if you will. AND this can be anything and not just what appears to be via my blue line.

For the life of me I can't get any kind of loft to appear much less then for me to have an idea of what to do to fix that. I get nothing.

Any help or thoughts are very much appreciated. HUGE thanks.

I'm no maestro, but here are a few thoughts:

• Your modeling is chaotic, and hard to work through with all of the transforms. I don't see why they're necessary for this piece, I think I could easily model this in place, so that the part history is more easy to work through.
• Loft can be tricky, I've modeled for a year+ (dozens of projects), and I still am careful to depend on it. If I think I'll need it, I often work out parts of my piece prior, so that I know I'll be able to reliably use it when I get to where I need it.
• If you're ok with a generally fancied up end, and don't require anything specific, rotating the end profile of the curved bit might be ok for you.

I did the last process here, though I actually did it after failing to loft, so I wasted a ton of steps. As-is, you could just make a sketch on the end of the curved bit, use "use/project/convert (u)" to grab the profile, and then rotate it by 90 degrees using the lower edge of the piece as the axis.

My doc: https://cad.onshape.com/documents/efa989742325d286ffa4022e/w/a31cabd71ec16b23a372e1ef/e/23b6344d641935f0ccf6b9f8

Another option is to rotate the blue spline curve you have by 90 degrees, then make a sketch on the end of the diagonal gray piece, extend a clipping outline around it, then Extend it as Remove to trim the rotated blue spline curve to fit. Perhaps merging the results only into the rotated blue spline curve. Use some Fillets to break the sharp edges.

Try adding a guide curve or adjusting the start/end profiles so they’re more consistent. Also, check for sketch errors or gaps. Happy to help more if you can share the exact tab you're working in!

It is absolutely chaotic no question. As mentioned it all started with a wing and a prayer not fully knowing what I would end up with. As mentioned, the place this ended up is inside a hard panier bag for a motorcycle of a friend. He asked that I adapt new never used parts without changing the cosmetics of the bag so….THIS :-)

Not being able to actually measure anything I did my best to eye ball things and then move them around until the part fit. It fits perfectly now and have finished the project but still not fully understanding why the loft won't work when I've lofted many times. So much of this if for the "next time".

Huge thanks for your kinds words and suggestions.

Scott, many thanks for reaching out. My brain gets stuck in a rut and need help clawing out of the ditch. I can't thank each of you enough. I've completed this chaotic task (remember, I started with nothing and no way to measure anything) successfully. The part still has what I consider a less than perfect end as I wanted to Loft here, but, it looks better than the early drawing as well as meeting my needs. HUGE thanks for your time and efforts.

Jarod, I greatly appreciate your help and offer to help more. I've since successfully completed this chaotic part. I'm never super at making all parts with minimal steps but this one was done with zero ability to measure the pertinent things/areas so with my old Eye-Ball along with many missteps, I got there. Doing this was fun but at times frustrating as I had to print the pieces along the way to verify fitment. Oh, and by using a long endoscope camera I was able to verify moving latch interfacing with this part. All is good even if I'm still not sure why my loft didn't work. Stray well !
