What is circular Xref in AutoCAD

Open options (DXF / DWG translation settings)

These are options in the DXF-DWG translation settings dialog box.

See DXF-DWG translation settings.

The options vary depending on the context. They include:

• AutoCAD block translation with the additional option of including 3D data in the resulting library elements

• The conversion of dimensions,

• Conversion file formats of images contained in AutoCAD drawings,

• 3D conversion if the AutoCAD drawing was opened as a library element.

• Filter the elements to be imported into ARCHICAD by level.

Further opening options can be found under Individual functions (DXF / DWG translation settings).

 

Open as floor plan

Translate AutoCAD Blocks As: Select one of the following options:

• 2D elements

• Grouped 2D elements

• Library elements

If you select 2D Elements or Grouped 2D Elements, all references to all blocks are broken down into simple floor plan elements.

Convert dimensions to:

• Lines and text: You do not create a dimension chain from the original dimensions, but use the drawing details saved in the file to achieve the same appearance (lines, markers, colors, text positions) as in the DWG file.

• Dimensions as individual units: All dimensions in the DWG file are converted into an ARCHICAD dimension chain.

Note: Dimensions have different characteristics in ARCHICAD and AutoCAD. Not all of these visual features can be reproduced in the conversion. The most noticeable difference is with markers: ARCHICAD has a fixed set of markers, while AutoCAD allows you to design your own set.

• Dimensional Chains: Only separate 2-point dimensions are available in AutoCAD (although there is a method of creating sets of dimensions that look like dimensional chains).

Associative dimensions where possible: In older versions of AutoCAD, the dimensions were not associative in the sense in which they were in ARCHICAD; H. not coupled to the hotspots of other elements. If you select this option, the add-on searches for elements that have already been imported to which it can assign the associative dimension. This can be very time consuming. The default behavior is therefore to create hotspots on the element and assign the linear dimensions to the hotspots.

Note 1: When radial dimensions are concerned, they always need a circular element to which they can be assigned.

Note 2: The latest version of AutoCAD includes associative dimensions for certain elements that cannot be converted.

Note 3: ADT has also introduced a type of associative dimensions, but this can only be assigned to ADT objects

Import viewports as embedded drawings: Check this box to ensure that AutoCAD viewports are imported as embedded drawings after opening a DXF / DWG file in ARCHICAD. If you uncheck the box, viewports will be converted to ARCHICAD panels instead.

Convert images to format: Select a file format to be used when converting images. Either keep the original image format or select a different image format in the popup as a uniform format for all images.

Open as a library part

3D data in library parts created: Select one of the following options:

• Binary 3D: The 3D information is stored in binary format.

• GDL text: The 3D information is stored as GDL text.

When processing the 3D data, the "Binary 3D" form is recommended: it is much faster if the text does not have to be recompiled each time the 3D view is generated.

Note: The "Open Object" command is the only way to get all 3D data saved in a DXF / DWG file!

Enable partial opening

Check this box and save this setting as part of the translator in order to filter the elements of the DWG file to be opened, uploaded or used as XREF in ARCHICAD.

In this case, when you use File> Open or Upload with a DWG / DXF file or attach an XREF file, the DWG / DXF Partial Open dialog box appears with the layer set and the layer status of the source file.

 

Uncheck the layers that you do not want to include in the ARCHICAD project.

This feature allows you to limit the DWG conversion to only the layers you really need. In doing so, you increase the conversion speed and reduce the size of the resulting ARCHICAD project. When attaching XREFs, the layers that you do not mark here will not be added to the layer attributes of your ARCHICAD project.

Convert 3D solids, regions and bodies into GDL objects

Check this box to convert the listed items to ARCHICAD GDL objects when the file is opened.
