Importing and Exporting

Importing and Exporting models to and from SkyCiv Structural 3D

Importing

Importing from CAD (.dxf)

A common issue for engineers is obtaining an analytical or structural analysis model from CAD software. The reason for this is because CAD and Structural Analysis software use different data – CAD is about geometries and faces, where as Structural analysis software requires nodes and elements to perform finite element analysis.

Currently, the best way to export from general CAD software to Structural 3D is via DXF. DXF (Drawing eXchange Format) is a CAD file extension that provides graphical data in the form of points and lines. You can export DXF from the following programs:

  1. Microstran by Bentley
  2. SAP2000 by CSI
  3. AutoCAD by Autodesk
  4. Revit by Autodesk
  5. Rhino
  6. Tekla Structures by Trimble
  7. SketchUp by Trimble
  8. VectorWorks by Nemetschek Group

Importing from Revit (.rvt)

Currently you can import a Revit model into SkyCiv in two ways:

  1. If you have Revit installed, you can download our SkyCiv – Revit plugin. This will allow you to push any model from Revit directly into your file storage in SkyCiv with a click of a button
  2. If you don’t have Revit (or simply don’t want to open Revit), you can import your Revit model (.rvt) by clicking File – Import from within SkyCiv Structural 3D. Click here to learn more about how to import a Revit model into SkyCiv Structural 3D.

Importing DWG (.dwg)

SkyCiv has built a DWG importer to help engineers get their drawings to structural models faster.

  1. Dimensions and scale is handled for you
  2. Upload a DWG and click the SkyCiv button (at the bottom) to start tracing your members
  3. The markup tool will snap to lines and edges
  4. Click Get Elements from Drawing to pull the lines into the table on the left to review
  5. Click Import Model to transfer to S3D
  6. You can go back to your drawing at any time by clicking File – Import – DWG

Importing from Excel (.csv)

Models can be generated and imported directly from Excel in two ways:

  1. Importing a CSV of your nodes and/or members. You can import your nodes simply by clicking File – Import – CSV from Structural 3D. Simply follow the instructions on the format required.
  2. Using our Excel-SkyCiv template: this will give you a good starting basis to use Microsoft Excel to generate and import a model using our API

 

Exporting

SkyCiv can export models in a range of file formats to support two-way data transfer. SkyCiv can export the following file formats:

Exporting DXF

See above for more information on .dxf file formats. SkyCiv will export your model in either:

  • (3D) – nodes and members
  • (2D) – drawings

Exporting to Revit (.rvt)

Revit models can be exported by simply clicking File – Export – RVT. This will provide a documentation-ready model to open up in Autodesk Revit.  The analytical model will export all necessary data into Revit, including members, sections (families), supports, loads and materials.

Exporting a STL file

Your model can be exported as an STL file, which is a primitive CAD file format. This will export the model as it seen in the 3D renderer. It is important to note that since this is an analytical model, members will be connected at their centre-points, so there is likely to be clashes like so:

Exporting to SkyCiv API

Models can also be exported into their native SkyCiv (JSON) format. This gives users a good basis if they want to use the SkyCiv API to automate and create custom solutions to their structural needs. The file format is JSON – a JavaScript object which is an intuitive, readable file format used to store data.
