Completting a half oval banner.
-
Hello,
I would like to kindly ask for help with finishing a complete surface on a portruding banner. The shape is half oval and it goes smooth until it hits the corners.
I tried to to do it by drawing additional lines and finishing it piece by piece using create surface from contours by it does not look good and its just sluggish work.
I am attaching screenshots of the problem as well as the sketchup file.
I will be grateful for any smooth solution. Thank you.

Temporarily hide the corner component. Delete the arc on the end but leave the angled line on the back. Get Push/Pull and hit Ctrl. Pull the end face of the rail out beyond the angled line. Orbit around behind and Push the triangular face on the back out through the front a ways. Select all of the geometry, right click and choose Intersect Faces>With Selection. Erase all the edges on the waste side of the bevel. Correct face orientations as needed.

WOW, that was so easy after your explanation. Many thanks i have been racking my head how to do this.
Thank you again! -
Dave's solution is spot on, but it's important to understand the underlying geometry.
You mention trying to create the faces with from contour, but simple stitching works because that is what the faces are made of. Lots of triangles.
Turn on hidden geometry from the view menu and stitch the edges together then soften the edges with ctrl+ eraser to make the smooth faces.

I'm glad that helped.
If I were doing that from scratch, I would just extrude the half oval rail longer than needed in a single go. Then put in the diagonals on the back and push the faces through. It would be a few less steps than needed to "fix" what you already have.
keep on plugging away.
