Modeling of stairs as linked element

Start by drawing the 2D-layout of the stair and there’s currently some rules for creating a valid layout:

• Only lines, polylines and arc are allowed.
• For a “revolving” stair we don’t allow one complete revolution or more.
• The “sides” of the stair must consist of either only lines or only one arc (helix stair).
• All the “steps” must consist of straight lines.
• NB! This functionalities is not working in BricsCAD (any version) at the moment.

In the “Layout” box you have two buttons one for selecting your 2D-layout of the stair and one for switching the direction of the stair. When selecting the layout, you will also be asked to specify and insertion point and rotation of the stair, this will be used later for the linked element.

In the “Dimensions” box you can specify the height of the stair and if you want a different height for the first and/or last step of the stair, if these are set to zero, they will have the same height as all other steps which is shown in the last property of the “Dimensions” box. All dimensions can be picked from the drawing using the “Pick distance” buttons.

In the “Recess first step” and “Recess last step” boxes we can specify a recess in the bottom of the first or last step. In the preview of the stair you can use a “right-click” menu for changing between different views and view settings, you can also zoom by using the mouse wheel, pan by using the mouse button and orbit by using shift key and the mouse button.

In the “Linked element” and “Location” boxes you can specify the element mark, building, floor, phase, and elevation for a linked element that will be drawn as the representation of the stair. If you chose not to draw the stair as a linked element a “plain”

AutoCAD solid will be drawn as the representation of the stair instead as seen in the clip below.

By selecting the “…” button next to the “Element mark” combo box, you can specify a new linked element mark for the stair and some properties as the length, width and height are already calculated by using the insertion point and rotation of the layout and the size of the stair, the volume and mass properties are also calculated. When drawing the stair as a linked it will automatically be saved in the database and you can also continue to add more elements on different locations in the model, for instance different floors and elevations as seen in the clip.

Modeling of stairs as linked elements, “Edit Stair…” and “Mirror Linked”

By drawing the stairs as “Linked” elements you can use the “Edit Stair…” command to get back to the “properties” dialog, and you can also you “Mirror Linked” to mirror the stair.
