  • Lesson 24 Overlay 2d Annotation

    All team leads, trainees must know how to overlay 2d annotations to IFC model and upload to trimble connect.

    Please watch this youtube video on it. I am asking Ragul to upload a training model with GA and Assy drawings. What you have to do is follow the video, extrat the dwg and upload the GA and Assy drawing to trimble connect on your private trimble connect.

    You may use campus for that. Get Ragul to check and approve.

  • Tekla Custom Component Primer

    Part 1 of the custom component take you through the following items.

    1. Defining parameters
    2. Setting Create option in the Component tree
    If you want the model please submit the form below. We will email you the dropbox download link

    NCDXF Files and & CSK Bolt Holes (in Tamil) from Tek1 on Vimeo.

     

     

    Hi team, please review the video for CSK bolt holes and NCDXF Files – language is Tamil.

  • GRASSHOPPER- THE VISUAL PROGRAMMING LINK FOR TEKLA

    Ever wondered how to automate the processes in modeling of steel structures, increase efficiency and accuracy. Grasshopper has got all the answers. Grasshopper is a visual programming interface like the Dynamo we saw in the previous blogs. It is built in within the 3D modeling software called Rhino. Tekla has released a link which enables algorithmic modeling for Tekla Structures using Rhino/Grasshopper. Even the toughest and tiresome models can be easily created using the Grasshopper-Tekla Live Link provided you have a strong visualization capacity and good understanding of the underlying geometry.

    We have tried using it for our jobs and it provides great flexibility to alter the parameters. One of the job we used for is creating a Spiral stair and the process was pretty easy and we got accurate results. Another challenging  job we experimented was the outer framing for cladding panels, along the sides of a bridge which had a tricky geometry. Have a look at these in the following video.

  • DYNAMO: MODELING COMPLEX STRUCTURES

    When it comes to 3D modeling, there always exists limitations with conventional modeling software while working with complex structures. In business, it is very important that each and every need of the customer must be fulfilled without compromise. With these things in mind we started experimenting various ways to model complex structures. Dynamo came into help here. The main advantage of using Dynamo is its accuracy and speed.

    We have done a aesthetic facade for an atrium using Rectangular hollow steel section which comprise of a Sine wave geometry in its elevation. Without the need of creating each and every piece individually we created a script which automatically generated the facade with the required profile. The final output was really accurate which may be limited when doing it manually. The size and shape of the overall model can also be adjusted easily to our requirements by using Dynamo.

    If you want us to model any challenging structure like this, please do contact us.

     

  • DXF problems when using Polybeam “L” shape plates

    The DXF format is a CAD data file format developed by Autodesk to allow data interoperability between AutoCAD and other CAD programs.

    Issue: One issue we faced when using the polybeam comments feature in Tekla is that if we used the feature to add comments on a DXF file imported into Tekla, then the output drawing will render the proper shape.

    See the image below for the plate shape.

    Try a contour plate.
    This won’t work. This is best modelled as a countour plate.

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

     

    See the below for the DXF output shape. The bending portion will not appear properly.

    DXF – this is output. It won’t work with polybeams.

     

     

     

     

     

     

     

    Solution:

    Don’t use poly beam comments in Tekla model to the “L” shape plates.

    Instead, use the Contour plate comment to make the “L” shape plate in model.

     

  • Using Polybeams rather than Curved Beams when modelling in Tekla (if NC files are required)

    Have you ever created NC files for curved beams in TEKLA?

    Generally, if you want to create an NC file for curved beams, the beams should be modelled using the Polybeam option. Because TEKLA will not create NC files for curved beams if you model them using the curved beam option.

     

    Choose polybeams when NC files are required.
    Choose polybeams when NC files are required.

    Let’s consider the situation where you’ve done all the work using curved beams. But, If the fabricator asks for NC files for those beams, you will not be able to create NC files. You’ll have to rework the entire model.

    To eliminate this kind of rework, we suggest you model the curved beams using Polybeam option in TEKLA.

    Summary: “the DSTV standard does not support curved beams, so Tekla Structures does not create NC files for curved beams. Use polybeams instead of curved beams”

     

  • Check Integrity of your Model file with CRC checker

    We have modelers very nervous about someone has inadvertently changed their model once they saved and left for the day.

    We can check the integrity of the model using MD5 checker.

    We are using software from http://getmd5checker.com/

    You take the .md5 file with you and next time you want to make sure of the file simply run the check again
