Discover the straightforward and efficient process of drawing stairs in a two-story building using a CAD file as a guide. Master the manipulation of base and top levels, the creation of risers, and the smart ways to trace and adjust stair placements.
Key Insights
- When drawing stairs, the first step is to set the run width from the architecture tab, which accelerates the process.
- Creating stairs in a two-story building involves ensuring that the base and top levels are correctly adjusted according to their desired positions.
- The CAD file acts as a guide, and it can be traced to draw the stairs exactly where needed. Adjustments might be necessary, especially in cases where existing CAD files do not accurately reflect the stair placement.

The time has come for us to dive in and draw these stairs and I think this is going to be probably the easiest process for us to draw stairs in this course because we have something to trace and if you remember when we look over at the CAD file there was actually even a guide telling us how wide it needed to be so it should be pretty straightforward and we should be able to draw these pretty quickly. Let's keep in mind that we are on that existing level one here and we will be drawing this as an existing phase so just like any other process for drawing stairs that we've done in the past we're going to go to the architecture tab stair and we're going to set that run width as the first thing we always do because that's just going to make things a lot faster for us. Then we're going to go ahead and draw this in and I always just double check.
I've been doing this a long time and for some reason I still don't trust the program to do it for me but making sure the base level and the top level are set to exactly what we want and in our case it's a two-story building so level one to level two makes a lot of sense. So I'm going to go ahead and I'm going to start by drawing it from somewhere along this point. We can use this midpoint that'll probably save us a little bit of time but we might have to make some adjustments after the fact so let's just keep that in mind.
So I'm going to start here and then we'll run it out until we get to our last riser on this side which you can see we've got 12 risers created 13 remaining and then we can just continue and do the same thing on this side if we can find that point that we're trying to grab onto here and then we can finish out the stair and draw the rest of it here like you see and so what this did is it gave us the 25 risers that we were looking for based on that seven inch max riser height and now we have our stair drawn in and because we had the template it allowed us to trace it exactly where we wanted it. So I'm going to go ahead and finish the sketch and then I'm going to take a look at what it looks like on level two. Looks good so you can see the stair is coming in through to level two at this point and it was a little different so this is pretty common you'll run into this a lot when you get existing CAD files the stair might not accurately reflect what is there and so you might have to make some changes so in this case we actually needed that extra riser and so what I'll do is I'll take this line and I'm just going to drag that one down because we don't really need to worry about if there's a space there because it's on the level one below.

We'll finish that sketch out to adjust our floor again and then what's great here is because the building is going to have the same stair we can either copy or mirror this across and I'm going to do that from level one and I'm going to grab the stair and it's important to grab the host element which is the main portion of the stair and not like one of these other portions like the railing or something like that and so I'm going to copy the stair selecting it and I want to pick a known point known point meaning maybe this corner because that's right on the wall not just something random so that I know I can translate it to this side of the building and so I can go from that point on the stair to the same point or a very similar point on this side of the building and so if I were to do the same thing here and place it in we're going to get a very similar result like you see here and let's check it out on level two we should end up with a very similar situation where we need to make an adjustment and that's me just grabbing the floor editing the boundary and then adjusting it accordingly so let's take a look at it in 3D and I'm going to turn on the section box here so that we can kind of take a look at it move this thing around and check out the stairs look good windows look good got the floor in there these guys look right and then we can look at the other side as well everything's looking pretty good there and then I'll bring it in to look at that stair and you can see looks pretty good all right so that's what we have for our existing building our stairs are created and let's take a look at our floor plan now so if we go to existing level one we can see that we've created all of the elements so we've got the door here these exterior doors all the curtain walls and everything's created so now we're ready to phase into our next portion of the project which is demolition
