How to enter and edit Dimensions

To display dimensions in 2D we have a number of different display options and additional properties, like for example decimal places and DIN standard representations. Furthermore dimensions use also standardly their own units. So it is possible that you work in the planning phase of your project in meters, but you enter the dimensioning in millimetres.
In this Video-Tutorial we show you three different methods how you can add dimensions to your project.

The basic workflow:

To enter dimensions in the same distance we use the help of guidelines (“2D & Layout” – “2D Guidelines” – “Guidelines”). Therefore we create guidelines in the same distance around our project on which we can place in a later step the dimensions.

Option 1 – Single Dimensions

  • For the first option we select “2D & Layout” – “Dimensions” – “Single dimension“. To define the properties of the dimension we make a right mouse click – “Properties“. In the general settings we can choose between different appearances and text position. We can also define the text properties at the point “Dimension text“. At the point “Details” we can edit the line properties for the dimension line, the dimension guidelines for the length and the dimension line end symbol.
  • We enter the dimension line over two points. Therefore we select a start and an end point. After it we position (for example on a guideline) the dimensioning. To enter 100% vertical and horizontal lines we press during the entry the “CTRL” key. To end the function we press “ESC“.

Option 2 – Multiple Dimensions (n points)

  • We select the second option under “2D & Layout” – “Dimensions” – ” Multiple Dimensions (n points)“. We can define the properties for this function in the same way as in option 1.
  • The function Multiple Dimensions (n points) is a dimensioning of multiple points on a common dimension line. We select a start and an end point, we press during the entry the “CTRL” key for 100% vertical and horizontal lines and we select the different points for the multiple dimensioning. After it we press “ENTER” and we position the dimensioning (for example on a guideline). To close the function we press the “ESC” key.

Option 3 – Automatic multiple dimensions

  • The third option is selectable under “2D & Layout” – “Dimensions” – “Automatic multiple dimension“. To define the properties we use the same steps as in option 1.
  • For the function automatic multiple dimensions we have to enter a start and an end point. With this points we define the length and the direction of the dimensioning line. All objects under the dimension line will get dimensioned if they are foreseen for the automatic dimensioning (for example windows, doors, walls, etc. …).
  • Therefore we select again a start and an end point (we press during the entry the “CTRL” key for 100% vertical and horizontal lines) and after it we position the dimensioning line.
  • The big advantage of the automatic multiple dimensions is, that when there are changes in the project (for example if we add a window to the project), it updates itself automatically. This function is only available at the automatic multiple dimensions.


  • To define dimensions after they are positioned (for example the text properties), we select the dimensioning – right mouse button – “Properties“.
  • When we select under the point “Input Text” in the text properties the function “Link to scale“, the text size change if we change the scale of the project
  • To move single dimensions in a dimension line, we select the dimension and we choose in the selection menu the function “Move with reference point” or we select the function with the shortcut “r“.
