Exporting CAD objects into Relux

Kurt Bieri

With Relux CAD, you can now also easily export 3D objects from AutoCAD into your Relux projects via the clipboard.

To do this, start a Relux project in parallel to AutoCAD and, in AutoCAD, select the  Export 3D object command in the Reluxmenu or from the toolbar.

Export Relux 3D object

As many 3D objects as desired can be selected on the plan with Select objects. 

Once the selection has been completed, you should return to the dialog. 

Then, using the Copy to clipboardcommand, you can copy a Relux 3D object to the Windows clipboard in accordance with the set options. 

The Relux 3D object can now be inserted directly into Relux with the Insert command (Ctrl + v).

In this way, you can create the following as Relux objects from the AutoCAD objects:

  • elevated lines, circles, 2D polylines, etc.
  • 3D areas
  • 3D area shapes
  • polygonal networks
  • 3D volumetric shapes

Please note, however, that only “closed shapes” will generally deliver the desired results. 

Individual areas that do not form a shape with other areas are only visible from one side in Relux.

In Relux, all the selected objects are grouped together to form a 3D object with sub-elements. 

Each sub-element can have its own material allocated to it in Relux. 

When the transfer into Relux is performed, corresponding default materials are generated on the basis of the AutoCAD colours. 

These can be adapted in Relux. Which drawing objects can be grouped together to form a sub-element of the Relux object will depend 

on their colours and layers as well as on the settings selected in the Materials dialog:

“by layer” -> each object is given the colour of its layer (irrespective of any colour it may already have)

“from the object” -> objects retain their colour

Object classification:

Classify objects according to material -> all objects of the same colour are grouped together to form a sub-element.

Classify objects by layer -> All the objects on the same layer are grouped to form a sub-element.

some examples:

Relux Control centre with the above building

The Control centre allows you to define the surfaces of suitably-structured 3D objects. 

There you can make your selection from amongst the different reflectance, textures and materials (for the Raytracing calculation).

Absolute values on virtual measuring areas that are inside 3D objects (bounding box):

With the aid of Relux CAD 1.1, you can import any desired 3D objects into the Relux professional software. 

Relux Professional allows virtual measuring areas to be positioned inside these 3D objects, such as inside a building. 

The 3D objects can be of a highly complex shape under certain circumstances. 

The results for virtual measuring areas inside 3D objects should thus be calculated in “high indirect component” mode.
