With the Dimension tool, you can measure the distance between any two points. These two points can be the endpoints of any component (corner of a wall, slab, door, object etc.), the midpoint of any straight component edge, or the nearest point on the surface clicked on. You can also choose modular grid lines or crossings. You cannot choose midpoint or center point (as an Osnaps in CAD tools).
Markups and dimensions are only saved in the issue snapshots, not in the model. They are always set along on the surface of a component. They can be resized or moved after you have drawn them, but they maintain the same direction if you move them. You can change the colour and line thickness of markups and dimension markings.
To have the Add Dimensions dialog open when measuring, you need to enable it in Dimension Settings or from the 3D view context menu. To enable the dialog:
To add a dimension:
Select the Dimension tool from the main toolbar:
Click the first surface.
To measure the minimum distance between two components, use Ctrl + click (Windows) or Cmd + click (MacOS).
To measure between two free points, use Alt + click (Windows and MacOS).
Click the second surface. A line is drawn between the two surfaces, and the distance value is added.
In the Add Dimensions dialog, you can select the starting and ending points. It also offers options for adding the distance, vertical distance and horizontal distance. You can force the point into certain options based on component geometry.
To cancel measuring, press ESC.
To remove all dimensions, select from the following options:
Right-click in the 3D view and select Remove Dimensions from the context menu.
Use theHide tool and pick the dimensions you want to remove.
Ensure that the point of the cursor is over the actual bitmap of the dimension element, otherwise the object that the pointer is over will be hidden instead.
To change the color and thickness of the dimension line, go to Dimension Settings.
