I posted this thread on Mechanical Engineering - generic - should probably be here

I don't know how to move. Can you read this thread and comment:

Detail View - solid line vs phantom? What is standard? - Mechanical engineering general discussion

So, I just started using CREO and used the detail view callout tool. I was surprised that the circle drawn was solid. I asked a colleague, but we couldn't figure out how to change this. So, I went to SolidWorks to give it a go. No, SW is solid as well. You can change the line style - though it...

It looks like the pertinent standard would be ASME Y14.2 (link below; scroll toward the middle of that page). I don't have a copy in front of me, but it should be mentioned in that one or maybe Y14.3.

I like how the rivet is only visible upon magnification.

Is there a standard about not showing parts that should be visible in some views and not others?

Edit: This is a rhetorical question.

Also, this is unlikely to be a pure Creo / ProE creation as the old behavior for detail views was to exactly copy the visible entities from the reference view. Maybe there has been an enhancement to allow users to do even more work?

In this case someone would have to specifically erase the rivet model from the reference view -or- this is a fake job showing the part in the reference view and a separate view of the assembly that has been clipped to look like it is a detail view of the reference view, but is not. Also on the table, someone added the appearance of the rivet to the drawing because some software (looking at you PTC) doesn't allow a part model to be promoted to an assembly model, so if the drawing uses the part then it is start-over time if there is a change in the level at which operations takes place. Always an irritation when a block needs to have an insert added at a late development stage or, like in this case, to add a rivet or rivnut.

It seems there is.
The same standard CH took the snippet from says:

" 2.8 Partial Views
Partial auxiliary views or partial principal views may show only pertinent features not described by true projection in the principal or other views. They are used in
lieu of complete views to simplify the drawing "

It looks like the technique has its roots in 50-s / 60-s simplified/functional drafting aiming at reducing manual paper-and-pencil design time.



The idea become less relevant with proliferation of CAD systems, but some standards still carry recommendations clearly aiming at manual drafter.

For example, I am not aware of CAD system able to pull trick like this:

Creo can do exploded views. Make a filled section and I think that trick can be managed.

One CAD trick that they don't seem to have is to have the outline of the part entirely on the material side rather than straddling the boundary. Make the outline very thick and mating parts will have their outlines overlap in CAD in a way that real parts do not overlap.

The other that seems rare is to have hatching only around the border rather than across the full section; certainly useful for large section areas rather than filling the whole thing. I guess it was too tough to do while there were pen plotters and not one cared after the raster plotters arrived.
