Eccentricity of Wall Footing

I replied to a thread at AUGI regarding the Eccentricity parameter of a Wall Footing. They observed that Revit seemed to ignore their input and didn't understand what it was meant to do. In this case the width of the footing was less than the value they entered.

The parameter is intended to shift the footing over, from interior to the exterior face of the wall. The footing starts out centered on the wall above.

The maximum eccentricity is equal to (Footing Width/2)-(Wall Thickness/2).

The interior wall surface can be aligned (flush) with the interior face of the footing but not further, creating any overhang of the wall, which seems logical to me. A picture might help?

Fixture Units don't Update

I read a post at RFO that said the value for Fixture Units added up along a pipe run were correct at the pipe (in properties) but that tags attached to those pipes did not report a matching value. My first thought was that the system's Calculations parameter was assigned to something other than Flow. So I mocked up a quick test (using version 18.1.1.18 - 20170907_2315(x64) - 2018.1.1). Three families, two with the same Fixture Units assigned and one rogue.

I changed the middle fixture to be the same as the outer two and the pipe properties responded, the tag didn't (2nd from left). I took a look at the Calculations parameter for the Sanitary Piping System. This is using a stock Imperial Plumbing template. It's already set to Flow.

I switched it to None, clicked Apply, and the tags responded with this (Performance does the same).

I changed it back to Flow, clicked Apply, and the tags responded again but now they report the correct values.

I thought that there might have been a subtle change within the Mechanical and/or Piping settings that I missed when Revit 2018 arrived. I don't think there is though.

If you're counting on Fixture Units being added up and reported correctly in tags, you'll need to keep an eye on this. I've been able to wake up the tags by toggling between Calculation Settings for the Pipe System.

Added: Temporarily adding a pipe or altering the connected pipes also cause the tags to wake up. Also, just to make things stranger, changing the fixtures again I find the information displayed in properties of the pipe does not respond either, nor does a schedule of Pipes. However, if I have a Piping Systems schedule that does update as changes to fixtures are made.

Smooth or Stepped Stair Setting

I want the concrete corner stair to look like this.

When I finished it looked like this.. sad face...

A stair Run has two options for Underside Surface: Smooth and Stepped. Smooth is what I started with.

There are occasions when I want the underside to look like the second image above, if so I'd probably tackle that like THIS POST. In this situation I wanted the following appearance. I got it by changing the Structural Depth parameter to match the height of the stair.

Insert Data Row is Disabled

While working in a Room Schedule we can create new rooms via Insert Data Row versus placing a room in the model and having it appear in the schedule. This allows us to assemble a project's programming requirements early or at least at the same time as modeling activities are creating the building. There are two settings that will disable the Insert Data Row tool (using Revit 2016 at the moment). This is what it should look like.

If we don't check the Itemize every instance option on the Sorting/Grouping tab the Insert Data Row is disabled.

The other culprit is using the Embedded Schedule feature.

Careful out there...

Temporary Dimension Size and Reference Plane Names

The name that appears on a selected Reference Plane is based on its name parameter. If you find their names a bit small to read we can take advantage of the Temporary Dimensions Text Appearance setting to increase it. This is what it looks like at 8 point text.

This is what it looks like at 14 point text.

Ah, more betterer...

Web Update 7 is Innocent

A quick follow up post. I was wrong. What I thought was caused by the update is actually caused by the Snap setting Snap to Remote Objects being off.

I must admit it is a bit mystifying since I never turn it off or at least I can't remember I time when I wanted to nor do I remember doing so. Regardless when support gurus Trey and Danny challenged me with their questions I found it was off.

Fwiw, I'd prefer that it didn't impact grid and level placement editing behavior regardless.

At least it prompted me to deal with a couple hours of windoze updates I'd been postponing.

Import CAD - Orient to View

This is what the Autodesk Help documentation says about this feature at the moment.

Orient to View - This option is useful if True North and Project North are not aligned in your Revit project. If True North and Project North are defined identically in the project, then this option will not affect the way the import/link is oriented. The World Coordinate System (WCS) is used to orient the CAD file in the view.

If the current view is set to True North and True North is rotated away from Project North, then clear this option to align the CAD file with True North. If you select this option, the CAD file will align with Project North regardless of the view orientation. Note: CAD files are always imported into the current view from the top view direction. The CAD file is brought into the view assuming that the current view is a top view.

It also does something important or relevant when importing into elevation or section views. When people draw sections and elevations in CAD they are often doing so in the plan orientation of the file. It isn't all that common to see people reorienting their view in AutoCAD and then drawing those views oriented to Front or Back etc.

When we select this option and import such a file into a Revit elevation or section view it will rotate the plan of the CAD file into alignment with the section or elevation view. If not then the imported CAD file is aligned with the plan orientation of plan views and we only see the edge of the files lines in the elevation or section view.

If the option Current View Only is chosen then this On by default

Video Settings and DPI

Be aware that Revit does not support increasing a computer's DPI (dot per square inch) video/graphics settings beyond 150%, assuming your computer permits it all. There are numerous cases where doing so causes either instability (crashing) or just poor graphic display quality.

Access to Feature Redundancy

When we examine the Revit interface we find that we can change the scale of a view at the bottom of the view on what is called the View Control Shortcut Bar. If you happen to keep your Properties Palette open you've probably noticed you can just change the scale value there too? It's the same situation for Detail Level and Model Graphics Style. In the image below the items highlighted in yellow (even some running off the image) are all represented on the View Control Shortcut Bar too.

This can seem a bit odd or redundant to fresh eyes. If you've been staring at Revit for a number of years you probably remember when it was necessary to open a dialog to see those settings. The View Control Shortcut Bar let us change things without opening a bloody dialog box again. Today it seems a bit unnecessary to have some of the view control shortcuts, unless you close the properties palette.

As I've written before, in Revit there are numerous doors you can open to gain access to features, front, back and side doors...even some secret doors. Maybe they are bit redundant but if your cursor is closer to the bottom of the screen you can take the "side door" to scale or detail level instead of hopping on your scooter and driving up to the top of the Properties Palette. With the serious resolutions available on some monitors these days it could be a long ride.

Revit 2013 - Suppress Spaces in Dimensions

Revit 2013 changes the means to reduce the overall size of the text displayed in a dimension string, particularly noticeable to people using imperial units. It was tied to the project units and you had to alter a dimension style to not use the project units settings in order to use it.

This is the new location for the option, found in the Type Properties for a dimension style.

This means your dimension styles can continue to depend on the Project Units as well as suppress the spaces in dimension values. A subtle but more logical approach I think.

However in testing it appears to be broken... The option for Suppress Spaces exists in the the Project Units dialog. If I turn on the feature it affects dimension styles downstream and the option in the dimension style should then work as an option to remove it but it doesn't do anything. Odd...

Saving or Sharing Export DWG Layer Standards

The process has changed a bit for exporting to dwg (or DGN for that matter). We used to be able to export our own settings to a .txt file format for use with other projects. In Revit 2011 we had this dialog and Save As button.

With 2012 they've decided to capture our settings in a project file itself. They let us choose one of these four standards to use, or to use as the spring point for our own version.

The fifth option is to "Load settings from file...". Interesting that there aren't any files to use though. We are to capture our changes in the project and then, when desired, pass it along to other projects via the Transfer Project Standards tool.

I've posted the source files that the four export settings templates use because they don't appear in my 2012 installation anywhere. I recovered them from my 2011 installation. Interestingly the other three besides the AIA version didn't show up until I loaded each one in to replace the previous. As soon as I did that, the other files appeared alongside the AIA version. If you really want to edit the .txt version, to grow your own version, you can download them here:
