I have run into an issue in Sketchup tht is very agrivating and seams to be a drawing error within sketchup. I am using Sketchup 2017 Lite.
This error is where when drawing a line to connect to another pair of intersecting lines to form a surface, the point at which my ne wlight connects appears to not connect properly forming microscopic (1-2 pixel) gap preventing the forming of a surface where one should be formed otherwise. I call this gap microscopic becasue it is so small as to be invisible on the screen. so at first glane everything looks like the triangle is complete and a surface should be formed, but no surface is formed. Sometimes, only sometimes, I am able to zoom in to find the micro-gap and I am able to force sketchup to fix it, but only half of the time. Other times the gap seams to be so small that I can not zoom in close enough to see it. When I try I end up zooming past the intersection point all together and it vanishes from my view. This situation is completely inexcusable and intollerable. It causes a complete halt in model development when I end up with a hole that by all rights should not exist.
