Section jog makes a solid line in section view.

[edreaux]

When i create a section that jogs, the section view shows a solid line at every jog. Is there any way to hide these solid lines?

There is a solid line because that is where the cut is. If you cut a real part at a jog, you will see those lines (edges).

My brain was stuck in Sheet Metal (jog).

You can select & Hide the edges if you really need to, but Chris is correct, the solid line should be there to show where the cut is being made.

I understand why the lines are there. But it goes agains good drafting practices. (just looks bad)

 

[CorBlimeyLimey]

Sorry, I have to disagree. Just because it looks bad doesn't mean it's bad practice.
I believe it's good (and standard) practice to show the "cut" edges.

Anyway, as I mentioned, you can hide the edges you don't want to show.

I agree with CBL. It IS good practice. It is NOT good practice to have a section line and not show how it truly looks in the section view. It's all in the standards, all companies should have copies of them.

Technically, edreaux is correct, you do not show jog lines on an "Offset Section View". I don't have the ANSI Standards in front of me, I only have the book "Fundamentals of Graphics Communications by Gary Bertoline handy, BUT I found 2 sites that show the Offset Section:

http://www2.tech.purdue.edu/cgt/courses/cgt120/CGT 120 Week 6.ppt#14

http://www.coe.uncc.edu/~gkwatkin/ETGR1103/week_13_slides.pdf

As for section lines not showing how it truly looks, another example that goes against that notion is an "Aligned Section View". Go to page 8 of that PDF and look at view b. You will notice the section lines going through the bolt holes, but the view to the right is not "normal to the projection".

CBL, Hee hee
Would be an enhancement request for the option to remove the lines.

Here's another take on the stepped section. Which one makes more sense to you?

http://img128.imageshack.us/img128/7816/steppedsection2mj.jpg

When I was on the board, I was taught to show the "broken edge" symbol to help distinguish the sectioned edge.
___/\ ___ Not to any standards that I know of, but effective.

BTW, The view to the right of View B, page 8 (of the PDF), is not an Aligned Section View. It is actually a partial rotated view. It is showing the vertical section & the angled section simultaneously, with the centreline being the "pivot" line.

[smcadman]

Sorry amigo, even Solidworks backs me up on the Aligned Section View; enter that in the SW Help search, and you will see an example of it.

Regardless if it was drawn in AutoCAD, or on a drafting board using mechanical pencils, ANSI standards are ANSI standards. ANSI standards are what I used since back in the drafting table days, but I cannot tell you how ASME standards treat these 2 section views.

This may be a question for the "Drafting Standards & GD&T Forum", forum1103

OK, you got me there. (SW Help)

You can create an aligned section view in a drawing through a model, or portion of a model, that is aligned with a selected section line segment.

(The emphasis is mine.)

I never really thought about it before, but I understand now why they would call it that.

... but I must remember to contact SW & tell them to correct their error. (just kidding)

I do not have a copy of ASME Y14.3M, Multiview and Sectional Drawings, (my company feels the Global DRM is sufficient even though this and similar arguments crop up every time we have new drafting personnel) but, as I recall the jog line is to be shown in the section view as a thin line, but it is to be shown. CBL's image is a prime ecample of why. And it was always a blanket requirement, not a "when there isn't really an edge there, show a boundary for the hatching" rule. The second example given by smcadman is suspect, as the author shows material-specific hatching. Outside of architectural and civil engineering drawings the only hatch permissible on a drawing since 1972 is the generic cast iron (ansi 31). I suspect that example is tailored to the bells and whistles of AutoCad and not to the standards, which causes me to suspect the author's accuracy in the rest of the discussion.

In any case, I usually select those lines in SW and make them thin. I know others who hide them.

 

[CorBlimeyLimey]

That's a good point wgchere (making lines thin). You could also change the linetype to "Phantom" (or whatever) to further distinguish between the "real" feature edges.

[berkshire]

Thats great guys,
But what if you draw to British Standard 1192 ?
B.E.

 

[CorBlimeyLimey]

SW also has options for BSI data. I have no idea how closely it follows them though. What does the standard say regarding the above sections?

I took the question about ANSI standards and showing offset-section lines to the "Drafting Standards & GD&T Forum" and finally got some more replies.
thread1103-147332
Company standards may want you to show them, but ASME/ANSI says don't use them.
