AI Thread Summary
When drafting a drawing with varying scales, the detail view should reflect its scale relative to the actual object, not the overall drawing. In this case, a detail view at 4:1 should be labeled as 2:1, since the main drawing is at 1:2 scale. It's standard practice to have different scales for details and location plans on the same drawing. The scale notation should clarify the relationship to reality, with the first figure representing the drawing and the second representing actual dimensions. Proper labeling ensures clarity in communicating the scales used.

If I have a drawing (in this case, of a machined part) that's 1:2 scale, and I have a detail view that, in relation to the rest of the drawing, is 4:1, what do I put as the scale for the detail view? 4:1 (relative to the rest of the drawing), or 2:1 (relative to the real piece)?

You put it as the scale that you typed in the box. Relative to the real piece. Everything should be relative to real life not to the drawing itself.

That's the thing. The detail view is scaled differently from the sheet.

So under "Detail A," I put the overall scale of the detail drawing, not in relation to the sheet. 4X relative to the drawing, drawing is 0.5X, so "Detail A | Scale 2:1". Thanks!
 
"Detail A | Scale 2:1". Thanks!

That is correct.

It is perfectly acceptable and normal to have details at expanded scales, or location plans at reduced scales on the same drawing.

Usually a different scale from the main drawing would be reported in the title of the inset eg

Location plan scale 1:100

Detail at A scale 10:1

The first figure reported refers the drawing the second refers to reality so

1:100 means 1 unit on the drawing means 100 units in reality.

The word scale should not have a capital letter.

go well
 
Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
