Electrical Sub-Panels with Lugs in Revit

I recently had someone ask me how to use Revit to connect an electrical panel to another electrical panel via lugs.  This situation occurs at times in building construction where an electrical sub-panel is wired into another panel via the lugs in the first panel and does not actually use a breaker in the first panel.  This is not normal practice, but does occur.   (Note that this is different than having an electrical sub-panel that has main lugs and does not have a main breaker which actually DOES use a breaker in the panel that feeds the sub-panel.)

For our situation described here, Panel A has a 200 Amp main breaker that controls just the circuit breakers that are seen in Panel A.  Panel B also has a 200 Amp main breaker, but is wired into Panel A at the main lug prior to the Panel A main circuit breaker.  In this case, Panel B needs to show in Revit as fed from Panel A but does not utilize a breaker in Panel A.  By default, Revit will create a breaker on Panel A to control Panel B.  We do not want that to happen in this situation.

Revit 2015 R2 Release

Autodesk has released Revit 2015 Release 2 for users on the subscriptions program.  It is meant to update your copy of Revit 2015 whether it is a standalone installation or part of one of Autodesk’s product suites.  This seems to be more than the typical service pack and is available only to those on the subscription program.  It includes additional capabilities, as well as includes service pack items included in update release 4.  After Release 2 is applied, the build number will be 20140905_0730 and will say “Update Release 4″.  (Note that non-subscription users do have access to Update 4 via the update page, but not this R2 version of it.)  Revit users on subscription can access this update by logging into their Autodesk Subscription site.

Revit 2015 R2 does not have a file format change so you can continue to work with Revit users that continue to use the existing Revit 2015 release.

A big enhancement to this R2 version is in the area of sitework.  Autodesk acquired the SiteWorks site planning software from Eagle Point Software Corporation.  Sitework has long been an area of limited capability within Revit and this enhanced capability will please many users wanting to do more with that aspect.  Subscription members can download the new Site Designer Extension for Revit 2015 from the Product Enhancements portion of the subscription site.

According to Autodesk’s notes on this release,

“This update requires either the initial release of Autodesk Revit 2015 (build: 20140223_1515) or Autodesk Revit 2015 Update Release 3 (build: 20140606_1530) . Autodesk Revit 2015 Update Release 3 will need to be applied to any installed Revit 2015 which has either Autodesk Revit 2015 Update Release 1 (build: 20140322_1515) or Autodesk Revit 2015 Update Release 2 (build: 20140323_1530) applied. Installation will also be blocked if Autodesk Revit 2015 Update Release 4 (build: 20140903_1530)) has been applied, a full uninstall followed by a new install of Autodesk Revit 2015 will be needed in order to apply Release 2.”

 I installed this release without issue on my Autodesk Building Design Suite version which was running Update Release 3. Continue reading

End Double-Click for Revit Family Editor

If you are like me, you tend to accidentally double-click on families in a Revit project file and then end up opening them in the Family Editor when that is not what you want to do.  It seems that the faster that you work, the more likely you are to have this problem, which compounds the issue.  You can stop this from happening easily starting with the 2014 version.

Drag ‘n Drop Files Into Revit

Have you ever used the Drag ‘n Drop method of adding a file to Revit and wondered why it seemed to work differently than the last time you did that?  Well, there are actually several variables involved in that process.

First off, you may ask what I mean by Drag ‘N Drop files.  That is typically when you have a session of Windows Explorer open, pick on a file, and use the mouse to drag a file from Windows Explorer to Revit and release the mouse button when it is over Revit (drop).  This method can be much faster than using one of the commands within Revit to add a file and is commonly used.

Apply Electrical Panel Template to Panels in Revit

Electrical panel schedules are a very important part of designing and documenting the electrical portion of a building project.  The electrical panel schedules help with designing the electrical system by showing the power requirements on the panel to the designer and allowing the designer to spread the power requirement across the poles of the panel.  It is also useful for showing the electrician how to circuit the items assigned to the panel.  Those 2 different purposes may involve showing slightly different information on the panel schedule.  In addition to that, the facilities manager may even desire to see different information on the panel schedule.

Detail Level of Linked Revit File

Most building projects created within Revit will utilize linked files from other disciplines to show the various components within the building model.  When this is done, it is not uncommon for users to desire to see the other disciplines at a different detail level than their own.  This may be the MEP engineer wanting to see a Fine detail level in their view, but only see the Coarse level of detail in the Architect’s model.  It may also be the Architect desiring to see their model at a Fine detail level, but see the Electrical Engineer’s electrical devices with a Medium detail level to show electrical symbols and not actual electrical element modeling.

Regardless of the reason, it is definitely possible and even easy to have linked Revit models show different detail levels on a view by view basis.  This means that each view can be set differently per the needs of the view.  Also, each different Revit link can have different detail level settings from the other links within a view.
