Join Paul F. Aubin for an in-depth discussion in this video Adding filled and masking regions, part of Revit 2018: Essential Training for Architecture (Imperial).
- [Voiceover] In this movie, we're going to add the finishing touches to our stair detail and with a particular focus on filled and masking regions. So, we've already seen the results of filled and masking regions in several of the components that are here already in this detail, for example, this detail item break line right here actually has a built in mask. And these grips here are controlling the shape of that mask so when I edit the mask you can see that it's only covering up the stuff that it's on top of. So there's this masking region built inside of that detail component.
And this component right here for the stair pan contains a filled region which is giving it that concrete stipple pattern. So, a masking region is just a solid shape that you use to cover up things and a filled region is a solid shape that has some sort of a fill pattern and we can use obviously either one of those to represent really just about anything. So, let's start with a masking region. The first thing I want to look at is the stair treads look pretty good here but notice that I'm seeing this line work behind for the assembled stair.
Now, you might be tempted to just say well, let's just hide the stair and I'll show you that with temporary hide. The problem is that hides too much, and then I'd still have to come in and draw the items that we're missing. So, what I'm going to do instead is I'm going to do a masking region that just covers up the parts of the stair that I don't want to see. So to do that, I'm just going to reposition my views slightly here and I'll go to Annotate, and on the Region drop down I'm going to choose Masking Region. Now, you get all your standard sketch tools and you configure what sort of line style you want.
So in this case, I'm going to choose a medium line. And I can just use the simple straight lines or I can even use the pick lines. So what I'm going to do is pick this edge and this edge and then I'm going to draw a vertical edge here right along the piece of steel and I'll just draw that any length and then press Escape and draw another edge out here. Now, it may look a little odd that I've done it that way, well I just wanted to match the angles and the locations where I wanted all the lines to be, and I'll just clean it up with Trim.
So, I want to trim this one to this one, this one to that one, this one to that one and finally this one to that one. So that gives me the basic shape of the masking region I'm looking for and I'll click the Finish button and of course when I deselect it, now it's completely covering everything. Well, remember that 2D components have stacking order so all I have to do is select this masking region and on the Arrange panel here, send it to back. Now, it's important to understand that the Arrange panel is for 2D elements only.
So, when I send that to back, it only sends it behind all the other 2D elements. Sometimes folks think that they can actually use the stacking order commands with model elements, it doesn't with model elements. Alright, so let's continue and what I want to do here is the concrete that used for the landing, I want to thicken that a little bit and change the shape slightly. Now, rather than trying to do that in the model, I'm just going to simply represent it here that way with a detailed element and I'm going to use a filled region for that purpose.
So, I'll go to the filled region command and once again, I want to look at my draw shapes and my line styles So I'll start with medium line and pick lines again and I'm going to pick the top edge of the existing landing and the top edge of this piece of steel. Then I'm going to come out here and just draw another line vertically outside the mask and press Escape one time. Now I'm going to zoom in closely in this location here and I don't want to overpower the underlying detail element so I'm going to switch from medium lines to thin lines here and I'm just going to trace over this line and then trace along that angle some distance.
Now, I'm noticing here that this line for the landing is actually a little too low, I need a little vertical line right in there but I also need part of this line to move up. So, I'm going to go to my Split Element command and I'm going to split it right at that point. If I try to move this line, it'll try and move this one as well. So you see how everything moves together, let me undo that. So what I need to do is go to move here and check the disjoin check box. Then I can snap from here to here and it will allow that line to move without trying to move the other one.
Now, this piece that's left behind is still medium lines. So I'm just going to drop that down to a thin line like so, so you can see that that inner edge is a little bit lighter. Now I'm going to zoom out a little bit, trim this one to this one and then zoom out some more. Trim this one to this one and then finally this one to this one. So like so many of these sketch based shapes you have to make an enclosed shape in order for it to work. When I click finish, it will create the shape but notice that it's just using this diagonal cross hatch.
So, the other thing that you want to do when you're working with a filled region is look over here on your Properties palette on the type selector, and choose an appropriate fill pattern from the choices that are available. Now, in this case I don't have anything that represents concrete so I'm going to go to Edit Type and I'm going to duplicate and I'm going to call this Concrete. Now, all I need to do then is change the fill pattern to a concrete fill pattern. So, if I click in here a small browse button appears and then I can choose my concrete hatch from the list, click OK, and then OK again, and now I have a filled region that uses the concrete fill pattern.
And then once again, I can select this element and adjust the stacking order. Now, if I select this element and I send it to back, this one's going to go come in front of it. So I could just select this one and send it to back again or an alternative if I undo both of those, would have been to just take this mask and bring it to front. So, whichever way you do it you want to get the stacking order appropriate for the detail. Now there's other finishing touches that we need to do here. We certainly could add notes, dimensions, and possibly some other detail components.
I want to show you one more thing that sometimes folks like to do with the stair detail and then I'll just show you what the finished detail looks like. So, notice here that if I highlight this stair that beyond we've got those treads. Well, right now I can't see them. So what you can do is temporarily in this view you could change the visual style to a wire frame. Now of course, the wire frame is way too busy but it does let you see where the treads are. You have two approaches that you could take to sort of dashing in those treads beyond. You could go to a detail line, change the detail line style to a hidden line and just simply trace over these lines.
When you set this back to hidden line, you'll have these dash lines right here. Now, instead of doing that, what I'm going to do instead is go back to wire frame and I'm going to use my Linework tool. So we looked at the Linework tool in a previous movie but if I go to Linework, change to hidden lines, and just touch this top edge, you can see and I'll just do a couple of them, that those lines will remain. And that's an effective way to show those tread lines in the background and when you're done, the completed detail might look something like this.
I provided a completed version that you can find with the exercise files called Stair Detail Complete.
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.
