I am practicing with Inventor LT 2021 to get used to it, and learn more about how to manipulate things in it. I was practicing with the following sketch and I developed a bunch of questions about the sketch.
I can see the thickness of the main plate is 11 (noted just to the left of the overall 65 dimension for depth).
How do I position this main plate in terms of depth from the reference plane to the near face of the plate? I see a dimension that looks like 51 but that makes no sense to me as it mean it would be beyond the back face of the lower or left circles which are 38 (19+19 or 24+14) from the reference plane.
Is is safe to assume that the arm going from the middle to the upper circle has its back side flush with the front side of the main plate? Or is it notched/stepped in slightly? Is the back of the upper circle flush with the back of the arm?
The main plate is 11 thick, and the upper left circles are 14 thick. Assuming this was centered on the main plate that would 1.5 overhang each side. The general fillet note states R2 fillets. Is it possible to place an R2 fillet in that space? I was not sure if fillets had to be tangent to their mating surfaces.
At the back edge of the center, left and lower circles is a V mark. I am assuming this has a specific meaning in the machining/mechanical engineering world. What does the V mark mean? no fillet? (I come from the structural/bridge engineering world so not familiar with most symbols for parts)
When drawing something that has a tolerance to it such as the left ream hole 14.27 - 14.32, what size should it actually be drawn at in the model? I have been picking a nice number that is within the range then navigating to the tolerance for it and entering the max value and the minimum value.
I know if I was in an office I would go ask the engineer/designer/client for clarifications, but since this is just a practice sketch from an PDF online I don't have the source to ask.
This is what I have so far:
For those wondering why I have not accepted my previous question, I am planning to as soon as I work my way back to that question and try it again with some of the new techniques I have learned by stepping back by more than a few examples.
