Stange Revolve embedded

I have used revolve with good results in the past, but the attached semi transparent Freznel lens has an atypical profile embedded within.  Saving as an STL file failed.  This object is considerably more detailed than others done successfully.  There appears to be something wrong with my sketch as I had difficulty around the solidifying the sketch around the revolve axis.

Hi @tjburke8BQFK 

When I've seen a revolve fail, it's usually because the geometry self intersects. But, it's hard to tell what's happening from the images. Can you export the .f3d file and attach the .f3d file to your reply? Creating a Share Public Link will also work.

Hi Dan: Thank you for responding.  I will try to include the f3d file
here.  One thing I did which might be the issue is, I modified a solid
bottom Fresnel lens by hollowing out the bottom for better light
transparency. I believe Where part of the original solid lens was
attached to the origin, is no longer attached.  I can always try to
coppy it back, but not sure if this is the issue or not.  Thank you.

Hi @tjburke8BQFK 

Thanks for the additional information. Unfortunately, I'm not seeing the .f3d file. Can you log into the forum post, Stange Revolve embedded and reply and attach the .f3d?

Thanks,

Hi Dan - Failed at sending the file.  Tried a few times, however...  I
ended up redrawing the lens and it came out perfectly. STL fiole is now
on mu desktop ready for slicing.  I need to be more careful when placing
a point on a line that ends up undefined.  This particular design is
somewhat complicated, so paying attention to details is important,
especially making incorrect assumptions when there is no warning is
possible.

I am making 2 red and 2 blue lenses for an old Railroad lamp. Evidently,
replacement lenses are made of unobtainium.

Thank you for your help.  Without your comments I wouldn't have decided
to redraw.

Hi @tjburke8BQFK 

Glad I was able to help. Another idea that will simplify the sketching. See if the following helps.

  1. Sketch only the inside or outside of the lens profile and draw a line for the axis of revolution.
  2. Use the Revolve tool on the Surface tab > Create menu.
  3. After revolving the surface, from the Surface tab >Create menu > click the Thicken tool. This will turn the surface body into a solid.

Let me know if this method works for you. 
Take care.
