Dimensioning fixes

Two quick LO dimensioning complaints that would be great to address:

  1. Section grips: Layout seems to be unable to “grip” to key points on a cross section. I know you can use the section plane to create a slice in Sketchup but that just seems like a ridiculous workaround.
  2. Dimensions disconnecting from model: This seems to happen to me a lot. Sometimes the “Reconnect to model” option works and sometimes it doesn’t, in which case I have to manually reposition the dimension leader grip. I’m not sure why it happens. Maybe I’ve developed a bad habit along the way? Maybe it’s a bug in the software that needs to be fixed.
