Addon for Revit - See, how InstaCrete builds the model for single flight stair easily.

In this tutorial, we will construct a single flight stair. Let us study the drawing. The grid lines are at 4000 millimeters. Open any elevation. The levels are at 3000 millimeters. Open the 3D view. 300 millimeters thick structural floor is from level 1 to level 8.

Let us come back to level 1. My aim is to construct a stair from grid 2 to grid 3. The stair is going to climb from level 1 to level 2. While constructing a stair we should prefer a sectional or an elevation or the 3D view.

Let us open the south elevation. I am going to construct the stair from left to right. From the stair menu, open single flight stair tool. In the dialogue box, select grid A for the east-west grid. Select grid 2 for the north-south grid. Select level 1 & level 2 as bottom & top level.

The number of risers is 17. Tread length is 250. Stair width is 1000. Let the waist slab thickness be 250 millimetres. Select right run for the stair run. Write the mark as per your requirement. The right direction arrow is already selected.

That means the stair is going to climb from left to right that is west to east. My stair starts with a riser & ends with a riser. Hit okay key.

InstaCrete prompts to select the bottom floor. Then select the top floor. The software uses the structural foundation family to build the stair. Now we will have to save that family at a proper place. Select the proper folder to save the file in the dialogue box.

Name the family & hit the save button. We see a warning message saying that “opening not cutting anything.” Click the cancel button. We can see the stair is not constructed.  Why did this happen? We will build a proper stair to analyse this.

Reopen the dialogue box in the elevation view. Repeat all the settings which we used last time except, select grid c for the east-west grid. We can see a proper stair in the drawing. Let us study the drawing. We can see 17 risers & stair is starting & ending with the riser.

Let us open the 3D view. Select the stair & hide it. We can see the cut on the bottom & top floor. Now open the level 1 view. Measure the cut. It is 900 by 1000 that is the width of the stair. I will revert back to south view.

We can see a proper smooth joint between the stair & the floor. A long-standing issue of the joint between stair & the floor has been resolved. Although we see joint lines in the top & elevation view.
