Revit 2020.2 - Internal Origin

A quick post to mention this since I've already run into this issue with users several times. The latest update for Revit introduces a new icon to mark the location of the file's Internal Origin. This is what it looks like in the 3D view.


It's off in all views initially, in the stock templates. Reveal Elements will display it quickly in a view without having to use Visibility/Graphics to show it. It can't be selected, it's just visible to help understand where it is.

Project Base Point - You won't see the clip when you select it. Move it away from the internal origin and it is automatically behaving as if it isn't clipped. In other words, it isn't clipped anymore. We couldn't really move the project origin, only the Project Coordinate System could be adjusted to provide a local coordinate reference for the Spot Coordinate tool, for example.

The Survey Point remains much the same.

When dealing with linked files you'll find that the icons for each of these is also visible but halftone (gray) to differentiate from the host file's own icons. You can snap to the links icon's to help align the files, using the Move tool for example.

I'll have to return to the subject once we've gotten fully acquainted.

BIM 360 Sync Failure Retry

Lately we've been experiencing some poor performance accessing BIM 360 projects. The primary cause eludes us at the moment, but Location Services, Windows Updates and Anti-Virus systems appear to be factors for now. Most of the time it works great but then...it doesn't.

Today I'm having trouble syncing changes with a project and this dialog has been stuck on my screen for about a half hour so far.


It's the fourth cycle of trying to Reload Latest... I think after a second failure to sync it should exit more elegantly. At this point I'm wondering how many times will it try before giving up? There is no option to quit or cancel...just stuck with forcefully quitting Revit at this point? That's polite.

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?

Reference Planes without Names

It is a common practice to add a name to the reference planes we create. If it isn't common where you work then it ought to be. The name helps give a hint to anyone that works in the model that this reference plane is more important than those without a name. It can also help understand what it is for, why it was made.

There are some who make the effort to clear out reference planes that are not named periodically, just another of any number of model/housekeeping chores. I've even seen Dynamo scripts intended for this task.

If you're using Ideate's Explorer you'll find it easy to see a summary of all the reference planes in the model. In the following image I've created two reference planes, one with a name and another without a name.


Notice that there are five (5) reference planes listed though. As it happens, when the Edit Profile concept is used on a wall four reference planes are created and internally applied against the sketch of the wall. They are only visible to us while editing the wall's profile sketch. We can't see these reference planes in the regular user interface, it only becomes very apparent with their Explorer tool.

It is also possible for us to create reference planes while creating any sketch based element, like a floor or stair for example. These reference planes are only visible to us while editing their related sketch.

The reference planes associated with a wall's edited profile can't be deleted via IDEATE Explorer. It can delete them when we've created our own within a wall's profile and other sketch based elements.

Attempting to clean up these unnamed reference planes might also be an issue if you're writing your own code or Dynamo script to delete them. We can/could add names to these internal reference planes (wall profile) but I don't think that's a task that worth the effort.

Something to keep in mind.

Structural Column Disappears - Part Deux

Yesterday while trading messages with a friend we discussed my previous post about columns disappearing. He suspected it might explain the issue he was observing. After looking more closely it turned out that it doesn't. In his situation the structural columns were modeled the full height of the building and Join Geometry was used on walls, that passed through (overlapped) the columns, at each floor (level). The result: at some levels no column appeared while at others they do.

It was necessary to pull the walls back so they stop at the surface of the columns. Join Geometry allowed for the desired appearance and the columns reappeared at the other levels where they were missing earlier.
