A reference model is a file that helps you to build a Tekla Structures model. A reference model may be created in Tekla Structures or another software or modeling tool and then inserted to Tekla Structures.
For example, an architectural model, a plant design model, or a heating, ventilating and air-conditioning (HVAC) model can be used as a reference model. Reference models can also be simple 2D drawings that are inserted and then used as a layout to directly build the model on. You can snap to reference model geometry.
Reference models of different formats, such as IFC, IFC4, IFCzip, IFCxml, tcZIP, 3DD, DXF, DWG, DGN, XML, LandXML, STP, IGS, SKP and PDF, are converted by the TrimBimConverter to TrimBIM (.trb) at reference model insert. The .trb file is saved in the current model folder. The reference cache is created in the cache folder based on the advanced option XS_REFERENCE_CACHE when the reference model is set visible, which happens automatically at insert and update.
The following file types are supported:
AutoCAD files .dxf
AutoCAD files .dwg (supported version ACAD2018 and earlier)
IFC files .ifc , .ifczip , .ifcxml
IGES files .igs , .iges
LandXML files .xml
MicroStation files .dgn , .prp
PDF files .pdf
Tekla Collaboration files .tczip
SketchUp files .skp (supported version SketchUp 2018 and earlier)
STEP files .stp , .STEP
Some reference models are automatically subdivided or split into reference model objects.
You can disable the roll-over highlight, which can speed up zooming.
Reference model plug-ins are available as .tsep plug-ins in Tekla Warehouse. Tekla Structures installation contains the plug-ins, but you can get newer ones from Tekla Warehouse. First download the needed package from Tekla Warehouse , and then import it to the Applications & components catalog.
For more information about .tsep packages, see Import a .tsep extension to the Applications & components catalog.
You can show reference models in drawings and adjust their visibility settings: Reference models in drawings.
