Join Paul F. Aubin for an in-depth discussion in this video Understanding selection toggles, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Instructor] In this video I want to talk about a slightly more advanced topic. We're going to talk about selection toggles. Now the reason I want to discuss it now is because a selection toggle prevents a certain class of elements from being selected. It's an individual setting that only affects each person's individual computer, so you could have the selection toggle set one way and your coworker sitting next to you could have them set another way but the experience you would have in Revit would be very different because where that person might be able to select link files, you might not because your selection toggle is turned off.
So understanding first of all that selection toggles exist and then understanding how you can toggle their settings on and off again will help you if you're trying to make selections in the elements that you're expecting to select are not selecting properly. So let's take a look at some of the selection toggles. Now we can find the selection toggles in two locations in the interface. So the first area is a bank of icons in the lower right hand corner, and then those same icons are available as check boxes on this little expandable panel right below the modify tool.
So the three features that we're going to look at here are Select links, Select underlay elements, and Select pinned elements. So let's start with Select links. Now we haven't talked about what a link file is yet but quite simply, a linked file is just another Revit project that's been brought into the current project for reference purposes. So if I kind of come over here and click this dashed line, you're going to see that dashed line selects as do all of the trees. That's because those elements are part of a linked file for the site plan information within this file.
Now I'm able to select it because I currently have the selectability of links turned on. So you can do that with this small little link icon right here, or you can do it with the check box for Select links. Now if I toggle that setting off here, you're going to see a small little x appear on the icon down here and vice versa. If I toggle it here, the same behavior will be true. If I toggle off the selectability of links, now no matter what I do, I won't be able to select the trees or the property line.
So it doesn't matter what type of selection I make, those elements become un-selectable. Now the primary reason you would do that is, sometimes when they're selectable, you're making a selection of other elements and you accidentally get the link file and you don't notice and then you can end up moving a link file inadvertently. So I'm going to Control + Z to undo that. So by turning off the selectability of links, you can prevent that from happening. So that's one use case for the selection toggles.
Now let me zoom in here on the underlay area, and you'll see that we've got all of this grayed out geometry here as an underlay to the first floor. So maybe the work I'm doing on the second floor, I want to use that information for a reference. Well, notice that right now I'm not able to select any of that underlay geometry. That's because the second selection toggle, in my case, is turned off. Now, if yours is turned on, you would be able to select it. So if I check it here, now notice that I'm able to select these elements.
So underlay geometry can be selected, and you want to be careful because it's live geometry and I would be able to actually move that geometry. I'm going to undo that. So that's one of the reasons that we toggle off the selectability of underlay elements. Now the final selection toggle is for pinned elements. Now, what is a pinned element? Well if I select this wall over here, this wall is free to move anywhere that I like. Okay, I'm going to cancel that modification. However, if I try to select column line D and move it, notice that it won't allow me to move it.
That's because it's got this little pin icon associated with it. Now that's controlled by these two little buttons right here, so you can selectively pin and unpin elements within your model. Now the reason to do that is simply because you don't want folks to accidentally move that object. You want them to think about it before they move it. So if I unpin it, then I would be able to move it to some new location and I'm going to undo that to put it back. Well as a further fail-safe, if you not only want the item to be pinned, but you further don't want anybody to be able to select it, then you can have the element pinned and then you can uncheck Select pinned elements and now, no matter what I do, I won't be able to select those grid lines at all.
So those three classes of elements are particularly valuable to have these selection toggles because those are the things where people make accidental modifications in the process of doing something else and they don't notice that they've changed the grid or the underlay or any of the linked files. So using those selection toggles, you can kind of prevent those sorts of selections from happening and from making those accidental modification. Now, moving forward for the upcoming videos, I'd like you to turn on the selectability of all three of those elements for the time being and then in the videos that follow, if I need you to uncheck one of those, I will alert you when to do so.
First, get comfortable with the Revit environment, and learn to set up a project and add the grids, levels, and dimensions that will anchor your design. Then author Paul F. Aubin helps you dive into modeling: adding walls, doors, and windows; using joins and constraints; creating and mirroring groups; linking to external assets and DWG files; and modeling floors, roofs, and ceilings.
Paul also shows advanced techniques for modeling stairs and complex walls, adding rooms, and creating schedules. Finally, discover how to annotate your drawings so all the components are clearly understood, and learn how to output sheets to DWF, PDF, or AutoCAD.
