I`m inexperienced at the moment.I have started a sketch but if i change dimensions say on the long thin rectangle the sketch falls apart..Also if i change a dimension on the top section of the sketch the lines move....what am i not doing
because the top section is not bound to the lower one, with other words it's not fully contrained.
BTW: please use the modelspace to design your model (not the paperspace/layout).

Are you familiar with parametric geometry constriants and dimensions?
Auto Constrain will tell you how many were missing.
But really - you should know what needs to be constrained (there is no auto-constrain out on the shop floor).
You have a lot of repeated dimensions - use symmetry and equal constraints. Use geometry constraints before parametric dimensions.
