BIM and IFC Reference

So you've been asked to provide an IFC file, and not sure how to organise your data in 12d Model prior to exporting.  Here is a quick reference guide for all the humps, bumps, and hurdles we've come across for getting your data out to the wonderful world of BIM. Before proceeding, there's one important [...]

MetaConnex

Introduced in 12d Model 15, MetaConnex is a suite of tools for creating, editing and manipulating attributes. When used alongside other 12d options like mapfiles and the attribute manipulator, MetaConnex’s power lies in not just helping to meet your projects BIM and Digital Engineering requirements, but ensures that required attributes on your data exist and [...]

MetaConnex Function Calls

Certain functionality can be applied to/with attributes using the MetaConnex Function calls. These calls will eventually get shipped with the 12d model V15 software. In the meantime, the below link will allow you to download the spreadsheet that contains all the current possible function calls that can be utilised within 12d Model V15.

Classify with Attributes

Classify with Attributes These options have been developed to allow users to group and arrange their 12d project data for selection or other purposes. The example might be the selection of all the "closed" strings within a group of models.  The standard 12d "data selection method" doesn't contain such a tool for this, but if [...]

IFC Writer Global ID and GUID

When 12d exports an IFC file each object is given a unique GUID.  If you export the same data again, the new IFC is created at a different point in time so each object is given a new and unique GUID. This can create problems for other software, such as Navisworks, as the GUID is [...]

Create/Edit Attribute Manipulator File

The Attribute Manipulator can be used to copy, move, edit, and delete Attributes from the Project level right down to Vertex.  Attribute Manipulator Rules are then saved to a file so that they are easily repeatable. The Attribute Manipulator also has the ability to change Properties, such as Name, Colour, Linestyle, etc. Utilities => Attributes [...]

Attribute Manipulator – Copy Segment & Vertex Attributes to String Attributes

The workflow below describes how to use the Attribute Manipulator to copy Segment and Vertex Attributes to String Attributes.  This is useful when data needs to be exported to software that only allows String Attributes (Meta Data). To create an Attribute Manipulator file, refer to: 12dwiki.com.au/attribute-manipulator In the Attribute to Use, set the Rule type: [...]

Attribute Manipulator – Concatenate Attributes

Major projects tend to favour long string/object names that define things like type, location, discipline, stage, etc.  Normally this information would be stored as attributes (metadata) on the object. The 'Attribute Manipulator' (AttMF) allows users to concatenate these attributes into single value.  Concatenating allows complex, project specific, string names to be built up from existing [...]

Attribute Manipulator – De-concatenate Attributes

This Post is Under Construction, please stay posted for updates. Along with concatenating attributes, the Attribute Manipulator can de-concatenate attribute values into separate attributes.  Even better, the new attributes can be placed into a group to make life easier when exporting to IFC. To create an Attribute Manipulator file, refer to: 12dwiki.com.au/attribute-manipulator De-Concatenate Attributes Syntax [...]

Attribute Manipulator – Calculate Values

The Attribute Manipulator isn't just for moving attributes around.  You can also do simple calculations, such as the volume of a kerb. In 12d we can easily get the length of a string, and we know what the cross-sectional area of a kerb is, so we can grab a calculator and calculate the volume. If [...]
