Hello Aspire experts....... More problems with the same model I posted a question on a couple of days ago......
Inspecting my 3D model, which now has 118 model components in 11 different levels, I noticed that the model went .266" below the "Z plane" when it should not go below zero at all!
When I had a similar problem 2 years ago, I found out from help on this forum that I had messed up by using negative base heights and negative tilt angles (as shown in "component properties"). My model was so loused up (for this and resolution problems), I had to throw it away, costing me to loose over 40 hours of work. Ever since, I have NEVER used a negative base height, or a negative "tilt" angle. So now I am fearing another messed up, unrepairable model.
Trying to isolate the source of my little negative offsets (which add up), I turned off different levels, and found that all of the negative offset came from one level. But within that one level, it seems as though 4 parts (not repeatably the same) contributed the negative offset. I spent over an hour, just trying to narrow down which parts were giving me the negative offset, and couldn't really identify which parts, as it was cumulative in small increments between several parts and the changes in negative offsets associated with each suspect component were not consistent. But it seems as though each suspect part had used a "tilt". (Again, NONE were negative, and I have avoided negative values like the plague!)
I can't have my model change heights depending upon which parts I turn on or off. But I can't figure out how to identify this, and I don't know why this has happened since I have used no negative tilts or base heights in making this model. Looking at each part's component properties shows no negative values, but I can find small negative values by using the "Scale Z Height of Model" tool to inspect each part. This is murderously tedious.
What do I do? Why do I get these tiny negative offsets on individual components, when I haven't used subtractions, negative tilts or negative base heights??????? Can I block my parts from going negative?
Help,,,,,,,,, this is driving me crazy...........
especially since this happened to me before and I thought I knew how to avoid this,,,,,,,,,,, Thanks, Chuck
