Line Crashes Sketchup - Solution

Matte

Good Day All,
I posted something I erased because I thought the problem is limited to me only. after 3-4 months of struggling I found a work around! This is probably a boring ramble not worth you time, but this fight was been consuming me and finding a solution had to be vented!!! Here was the problem, if anyone EVER runs into this, I can help walk through it with you if my explanation is unclear.

I created a "layer cake" stepped Topo. (Best for my needs) When I raise topo layer 1 foot above topo layer 0, Etc. A stepped topo is created. I have had MAJOR problems when lets say 1 of the horizontal rectangles is missing or I add "stuff" where a Horizontal piece is missing from the "ring" shape of that level. When I go from one corner point to the opposite side corner point..... The face is supposed to just fill in.... It crashes and kicks out of sketchup EVERY time! If really small drawing, I would just redraw it. But when you have a 40 or 50 MEG file with thousands of faces and only 20 or 30 areas of topo has this problem, not a desired choice.

Problem: (Vertical rectangle, Left + Vertical rectangle Right) We want to connect the dead space between the two with another Rectangle. "Normal" way... Draw line top Corner Rectangle Left to top Corner Rectangle right, Then the same on the bottom = Rectangle created.... NOT !!, computer crashes every time! Same for Horizontal surfaces!

Solution: (a few variations work, here is the WORST case scenario)

Draw a line Top to opposite bottom corners between each "rectangle", (creating a "bow tie")
Window the center crossing point, move strait (Down/Up, using down for this example) until lined up with the bottom of the side triangles, save,
(Now we have a bottom line with two triangles going from this centerline to the top of each side rectangle)
Draw a line from this bottom center midpoint strait up to height of side triangles,
Draw lines from the center point of each of these triangles to the top on the centerline, erase all the internal lines, and center height line.
-(Should have a "W" looking face at top of this "rectangle)
Now window around each of the lower intersections of the "w" and move up until it aligns with the top of the side rectangles, save... You new have the most difficult way to make a simple stubborn rectangle.... But it DOES work.

I double this has any value to anyone, but I hope I am wrong. A rarely have much to share, so here is hopefully "something"!!

PS The centerLine part is not usually needed, once you erase the internal lines And the face is in a V shape, you can usually just move that up/down to make your rectangle.
