Hello

I tried drawing a louver with an arced bottom profile and then lofted to a straight profile. For what ever reason it didn't work
Drawing straight lined Profile or a straight line profile with radius corners does . The Arced bottom profile has a bulge in the loft that turns into a hole when its sliced for printing

I ended up using the straight line one . Printed about 20 to create a mini screen to fit in a sliding door to keep rain and bugs out and it works great , no more wet carpet or huntsman spiders hanging on the ceiling.

would love to know why the Arc one doesn't work and what the work around would be

The fix is to select the top curve, "Show Points", select the pair of points in the center, and delete.

Now the point structure of both curves is similar.

Hi DigiD, it's because although there is the same number of segments in the top and bottom profiles, the segmentation is arranged differently.

For example this line on top is broken up into 2 segments, while the piece on the bottom that should match it is only one single segment:



So with the segment structure arranged differently like this, when the Moi Loft commands connects up each segment in the top curve to each segment in the bottom curve you'll get a mismatched result.

To fix it you could either control the Loft by lofting in more granular pieces like between each sharp corner separately rather than just one single loft between complex curves, or tune up the segmentation so there is a one to one matchup between the top curve segmentation and bottom curve segmentation.

If you do it with several lofts, then you would select the surfaces and use Edit > Join to glue them together and use Construct > Planar to cap off the planar top and bottom.

Thank you both

Both methods fixed it , Eds in one step more or less. Michael's method required cleaning up 4 lines .
I guess the bottom line ;) is use clean matching full lines when lofting
