When Pipe Settings is selected in the left panel, you can specify settings that are applied throughout piping, plumbing, and fire protection systems.
Click Home tabMechanical Panel Mechanical Settings.
In the left panel of the Mechanical settings dialog, click Pipe Settings.
In the right panel, specify the following parameters:
Use Annot. Scale for Single Line Fittings: is selected, to draw pipe fittings and accessories at the size specified by the Pipe Fitting Annotation Size parameter. Changing this setting does not change the plotted size of components already placed in a project.
Pipe Fitting Annotation Size: specifies the plotted size of fittings and accessories drawn in single-line views. This size is maintained regardless of the drawing scale.
Pipe Size Suffix: specifies the symbol appended to the pipe size that appears for Instance Properties parameters.
Pipe Connector Separator: specifies the symbol that is used to separate information when two different size connectors are used.
Pipe Connector Tolerance: specifies the number of degrees by which pipe connectors may deviate from their specified mating angle. The default setting is five degrees.
pnoypride17Wed Oct 26, 2011 8:29 amHi, I'm having issues about the size of my pipe rise/drop annotation on single line. I'm using Revit MEP 2012. Pipe fittings I was able to change the size onlye the drop and rise symbol I'm having a hard time. I would appreciate any help. Thank you
eric.greyThu Oct 27, 2011 7:33 amDid you try adjusting the Pipe Rise / Drop Annotation Size setting in this section of Mechanical Settings?
pnoypride17Tue Nov 8, 2011 8:03 amI figured out what was the problem but now I'm having a different issue. How can I show my flow arrows on my piping?
karen.smithWed Nov 9, 2011 7:40 amHi - Currently in Revit MEP, you cannot show flow arrows on piping. There is a workaround using pipe tags that is described here: http://www.augi.com/forums/showthread.php?t=84062 and here: http://www.revitcity.com/forums.php?action=viewthread&thread_id=19101. Hope this helps. - Karen Smith, Autodesk Revit User Experience team
ruifigueiredo5627Fri Nov 11, 2011 7:49 amThe Pipe Fitting Annotation Size option doesn't seem to have any effect on sections with a coarse detail level, although it works perfectly in plan views. I don't understand the reason for this, could it be a bug? The Pipe Rise/Drop Annotation Size, on the other hand, works, which makes the section drawings look unproportional (normal sized rise/drop pipes vs. small pipe fittings) and therefore, not usable at all. Help!
karen.smithMon Nov 14, 2011 6:05 amHello - Annotation scale only applies to plan view. In all other views, fittings display as unscaled 1-line. This is a known limitation in Revit MEP. Unfortunately, there is no work around. - Karen Smith, Autodesk User Experience team
salscrewSun Jan 8, 2012 10:06 amI can't seem to reduce the default value of 1/8" for the Pipe Rise / Drop Annotation Size to 1/16". 1/16" does work for Pipe Fitting Annotation Size however. Any thoughts? thanks, Sal.
karen.smithMon Jan 9, 2012 7:46 amHi salscrew - Try adjusting the unit precision for piping. From the ribbon, go to Manage > Project Units. Select Piping for the Discipline. Select the format for Pipe Size and change the value for Rounding. Click OK twice to save your change. Hope this this helps. - Karen Smith, Autodesk Revit User Experience team.
David_1982Mon Jan 23, 2012 5:33 pmWhile using Revit MEP 2012 I have observed the following: I am using a pipe accessory family consisting of 3D extrusions, two pipe connectors, and symbolic lines. I have noticed that when I change the depth of an extrusion with a pipe connector on it and load the family back into my project the size of the symbolic line representation changes - even though I did not change any of the symbolic lines in the family. In other words, changing the depth of an extrusion with a pipe connector appears to be changing the scaling of my symbolic lines. Also, it makes no difference if I convert the symbolic lines to model lines - their scaling still changes when I change the depth of an extrusion with a pipe connector. This makes no sense to me and seems like a bug. Is there some setting or property that I am missing that will stop the symbolic lines from changing scales when I change the depth of a connector with an extrusion? I should mention that this behavior only seems to occur when I have the “Use Annotation Scale” option selected in the properties of the pipe accessory instance in my project. Also, changing the depth of extrusions without pipe connectors in the family does not seem to cause the scaling of my symbolic lines to change, so it appears to be an issue related to the connector. I would greatly appreciate any insight into this odd behavior. Thanks.
jason.martinTue Jan 24, 2012 5:42 amThe annotation symbology that you are using gets "normalized" based on the distance between the 2 connectors used for the model geometry before getting scaled to the plot scale for the view, so changing the distance between the 2 connectors will effectively change the scale of the annotation symbol.
In most cases the annotation symbology is build in a "parametric" manner, tied to the model geometry. People don't typically want their 2" valve to show up a different size than their 6" valve, so we first scale the symbology based on the size of the model geometry, before applying the plot scale.
There is no setting to change this behavior today. - jason martin, Revit User Experience.
David_1982Tue Jan 24, 2012 8:39 amThanks for the explanation Jason! It sounds like the option to stop the annotation symbology from getting scaled based on the distance between two connectors is an item to add to the wish list. The work around I have found is to uncheck the “Use Annotation Scale” option in the properties of the pipe accessory instance in my project and draw the family symbology the appropriate size for the scale that I am using. The drawback to this approach is that I have to create a new family for each different view scale so that the symbology will appear the same size on all the sheets.
nfullerSat Apr 28, 2012 7:30 amLooking at the "Main" tab under pipe settings, there appears to be an ability to set a default pipe type and default offset for each system type. One would expect that when the pipe command is started and the system type is changed; that the pipe type would change to reflect the setting for the system type selected. Changing the System Type settings appear to have no effect. What do these settings control?
eric.greyMon Apr 30, 2012 11:26 amThose settings are used by the Generate Layout command. While selecting a layout solution, you can select the Settings button to see these settings being used. The system is determined by the connectors on the equipment and the pipe type is determined by this setting. Hope that helps, Eric
karen.smithMon Apr 30, 2012 1:14 pmHi nfuller - I've updated the first sentence in the Specifying Conversion Setting topic to make this a bit clearer. Hope this helps! - Karen Smith, Autodesk Revit User Assistance team
