false
Which guideline makes this correct?
Most dimensions are place on the view that shows the best contours.
Dimensions are place on hidden lines
Dimensions are inside the object
Holes are dimensioned by diameter, arcs by radius
What dimension guideline does this violate
When possible, avoid dimensions to hidden lines.
Dimensions should not be duplicated
Avoid dimensions over, through or inside an object
Attach dimensions to the view that shows the best contours
What makes this the correct practice?
Dimension a circle by its diameter, an arc by its Radius
Avoid dimensions to hidden lines
Dimensions should not be duplicated
Dimension an arc by its diameter, a circle by its radius
What dimension guideline does this image violate?
Dimensions should not be duplicated
Place dimensions between adjacent views

Top, left, bottom
Why is the dimension guideline incorrect in this picture?
The dimensions are duplicated.
The view is incorrect.
You should not dimension hidden lines.
