• Workflow

In principle, DDS-CAD recognizes the lines and points in the PDF file (vectors). However, in complex drawings this leads to a high load capacity on your computer. Refresh and other actions of DDS-CAD can be slowed down, the import may fail as well. The vector detection is therefore switched off by default.

You should try the application, since the vectors are used by the snap functions and will facilitate further processing.

An imported floor plan needs to be adjusted in size to the 1:1 scale. That is, a known size of an object (e.g. dimension line, door) must be verified by the function Measure Line and correspond exactly to the indicated length.

First, verify the situation in which you measure a known reference distance. In case the measurement result differs from the indicated length, you must determine the correction factor for scaling the floor plan.

• Measure reference line
• Determine correction factor to scale floor plan (bei erfolgreicher Vektorerkennung)
• Determine correction factor to scale floor plan (ohne Vektorerkennung)

We recommend to use the PDF file as a template to reconstruct the required drawing content with DDS-CAD. Reasoning

You create floor plans using the function of the building model (Skip to description »). For other content you can use general geometric functions. Finally, remove the PDF file again from the model and continue working with the original DDS-CAD objects.

Have you reconstructed the floor plan with the function of the DDS-CAD building model, you should make the embedded PDF file invisible. Depending on the processing status of the imported file, you can turn it invisible (to make it visible again at a later stage) or permanently remove it from the model.

• Hide imported file
• Delete reference to the imported file

The location accuracy of the floor plans is a prerequisite for future planning of floor openings and risers. When PDF files are the basis for the layout creation, and you have reconstructed the floor plans without first checking the correct positioning. You can assume, under these circumstances, that the floors have an offset and the correct position arrangement must be made.

Sequence for all storeys

1. Activate the Use Snap Points.

   Permanently activate / deactivate

   

   Activate temporarily   [Shift]

   You can activate the snap point function temporarily for a single operation.

   1. Press and hold  [Shift]
      When approaching an end, middle or intersection point, the cursor will be snapped. The current position is displayed.
2. Deactivate the  Use Ortho Mode
   

3. Move Area

   1. Select the function in Main Toolbar
      
      
       
      The information line shows:   [Click Left]=First point of area

4. Define the move area over the entire floor plan. Determine the diagonal of a rectangle by clicking .
   

   

   The information line shows:  
   [Click Left]=Reference point for moving area [Shift]+[Spacebar]=Define additional area
   

5. Click on the building reference point. A point in the building, which is identifiable on all storeys and is suitable for alignment of the consecutive storeys (e.g. the corner of a duct, chimney or staircase).
   

   

   The cursor drags the end of a dynamic line.

6. Press  [0].
   The dialog appears: Absolute Position
7. Set all the coordinates to the value 0.
8. Click OK. The completer floor plan is moved in such a way that the selected building reference point become the origin of the global coordinate system.
