What You See Is NOT ALLWAYS What You Get
Maybe this issue have been discussed before but I haven't found it yet.
I have discovered what I would call a major issue in Revit MEP and now I would like to hear what you think about it.
Revit 2013. Create a Floor Plan View. Detail Level is set to Coarse. Visual Style is set to Hidden Line.
Draw two parallel Pipes with a distance of 150 millimeters or smaller. Pipe size is up to you.
If the Offset value is the same there is no problem so you have to change the Offset value for one of the Pipes.
Add the Floor Plan to a Sheet and you should be able to see the two Pipes as single lines.
The problem happens when you print this Sheet. The lowest Pipe will be hidden. It happens in Preview, PDF print, hard copy, DWF Export.
It is the same with Conduits.
Back to the headline. What You See Is NOT ALLWAYS What You Get and that is the problem bacause the Sheet looks fine in Revit.
The solution Autodesk came with was to print as a Raster but this solution is useless because the quality isn't as good as Vector and you can't get any properties i Design Review because it's a picture.
My test project is attached and also a DWF Export.
I would like to hear any comments from you about this issue.

I would be interested to hear a cause from them. We draw stuff in arch thats closer than 150mm all of the time, and it prints correctly. However ive verified that its doing it, that it isnt related to the Coarse LOD representation, and that bringing the view range up on TOP of all of the objects (raising the cut plane) doesnt help. Thats icky.

It has to do with the Hidden Line settings within the Mechanical settings. Play with sizes of the Inside Gap, Outside Gap, Single Line size and they will print.

Thank you for the replies.
The Hidden Line settings within the Mechanical settings is of course the answer and changing these values will make the Pipes and Conduits visible when they are printed.
The attached Revit project was made by selecting None as a template and the default values are 1.6 mm.
Changing these values will also change how crossing Pipes and Conduits with different Offset values are displayed.
In the project I'm working at the distance between the Conduits is about 50 mm so I have to change the value to 0.4 mm at the scale of 1:100 to see them.
But with 340000 square meters I can't be sure that the distance won't be smaller and I still need to see crossing Pipes and Conduits which is difficult.
Back to the headline. If I can't be sure that visible objects inside Revit also will be printed then I have a serious problem.
Anyone who have some real project experience with that?

I think the default setting is 0.5mm for in the 2013 Mechanical template. I don't see a problem with this setting (0.4mm). Just tried two pipes side by side separated by 50mm and it prints just fine so I'm not sure what the problem is? Two pipes single line 50mm apart bleeds into the other but thats another issue. Put a section through it.

Reason: pipe distance edit

At the default template the Line Style is MEP Hidden instead of Thin Lines and because of that the Pipes will bleed together.
The problem is that we have to be sure that the objects we see at the Sheets also will be printed. That is not allways the case.
Isn't that a huge problem?

Not really. You said you needed 50mm between conduits. The setting of 0.4mm prints just fine?

I'm surpriced that you don't think it is a problem that there is a situation where objects are visible in Revit but won't be printed.
As I wrote previously we have 340000 square meters and I can't be sure that it won't be necessary to draw Pipes and Conduits that will be closer then 50 mm.
The thing with Revit is WYSIWYG and I can't be sure of that in this case.

You're missing the point. Play with the number of the Single Line setting and you will see your pipes. If you're still concerned, anticipate the closest spacing of pipes you think you will have then play with the number until it shows up in the print. Stick with that number and you're done. It really only happens when the pipes are offset vertically.

Sound like you are pretty new to Revit, so: Welcome to the game, in that regard.

There are a ton of ways Revit isnt perfect, and if you dont work around them, it can make your stuff *wrong* all day long, and twice on sunday. Heck, take a Brick Material Take Off where you have brick used in both family components and walls. Totally wrong. Half the game is learning what works, what doesnt, and leveraging that.
Or, you know, giving up.
