1. About this function

Create Beams with clicks! Our dwg recognising tools can help you create hundreds of beams in senconds!

Auto Beams

3. To use this function:

  • Go to the Floor View on which you want the created Beams and then click "Auto Beam" button.


  • In the pop-up window, you can find two columns of layers for extraction. MaxiAEC allows you to extract drawing lines in CAD file for Beam geometry. 


  • pick the beam outline in your CAD Drawing.

Extract Beam Outline

  • Annotation of beams are required to create building element with correct heights. Pick the annotation layer in the drawing, and the marks will be linked to the adjacent beams.

Extract Beam Annotation

  • The settings provide you some further options. You can decide how your beam elements will be named and created.

AutoBeam Settings

  • To help you round up potential irregular Beam sizes and manage the types of beam you want to create, you can define several beam width before recognisation.

AutoBeam Predefine Size

Currently, the Pre-define Beam Width is turned on as default to help you better recognise beams with different unit in cad drawing.

  • Also, when you find it difficult for the software to recognise beam marks, you can set a pattern for the mark to help the differentiation.
    (For example, if your beams are named as FB1, FB2 and so on, enter FB in the field for better effect).

Auto Beam Prefix

  • Click "start recognisation" to read the DWG file. You can preview the beam dimensions before creation. You can check the size and mark of beams in the table with your original drawings.


  • As you can see in the list, some of the beams are not assigned with a valid height value. That value will be replaced with a 1mm height and you can modify that property manually.
  • Marks and size properties can be manually changed, or you can use batch edit to insert data that was not in the table at once.

Auto Beam Batch Edit

If you want to extract data from a beam table, first click the "Extract Beam Table" button, and use window select to select a range of table in your drawing. If the table was successfully recognised, a table will pop up and the data inside can be insert to the beams that you are going to create.

  • After you have filled all the necessary data for the beams, click "Create Elements" to continue.
  • In 3D view, we can easily browse through the beam elements we have created. This image shows the created beams with accurate beam marks and properties.

Auto Beam finished with Properties

  • Some beams failed to get a valid height value and are marked with a red appearance to warn the user. You can manually replace that particular beam, or try to rerun the process.
