What do you do with dimension lines that overlap necessary geometry lines, as in this example drawing? (If you don't have room to draw another view, as in this example)
Click on one Dimension then Right Click, Select Similar in the menu then Draw Order, Send to Back.
This will get all with the fewest clicks.
OP this looks like a simple Inventor drawing. Do you mean where the "40" overlaps the notch on one side? You should be able to highlight the dimension and drag its grip to the edge of the item, where it should show a gap.These also look like you are using smart dimensions instead of choosing model dimensions, which would use the same dimensions you used to make the model sketch in the first place. Those would be black, whereas yours are gray.
Bob, I intentionally made a very simple drawing so it would be easy to spot what I was asking about.
Guys, thanks, but I'm aware of draw order and moving extension line handles. My question was about drafting standards more than AutoCAD functionality.
Even moved behind the geometry, an unbroken extension line doesn't read well to me. And if I end the extension line at the "notch," the machinist sorta has to guess that the hole is located in the same position. What about continuing the extension line to the hole but adding gaps (DIMBREAK) around the geometry? Would that be acceptable?
You can place dims on the object when it makes things clearer. Don't show the dimension twice as you have shown in your example, once on the front view and once in the partial section.
There should be a gap between the extension line and the object line.
If the center of the circle is colinear with the edge line then dimension to the edge line.
If the center of the circle is very close but not colinear with the edge line then a detail view is required.
Dimension everything from the left side of the object and over it, even the Diameter value (not radius). (Radius for arcs, diameter for holes and cylinders.) Now that edge doesn't come into play and all the dimensions are between your views, which is the preferred method.
