This blog illustrates how to provide the dimension detail in an efficient way for sheet metal bending using Tekla Structure. For bending of sheet metal, we need to provide add-on information in Pdf drawings and dxf files for calrity of fabricator.
By default the Tekla Structures can generate drawing with bend lines. But it is not sufficient for the fabricator, until he knows which side to bend the sheet. This can be achived using the plugin “DSTV TO DXF CONVERTER” available on Tekla Warehouse. (Note: Always check if the drawings are created in front view for high quality output.). See below image for clarity

Steps to show bending lines: When a DXF file is exported using Tekla it shows reference line. In order to add the bending lines we use the tool “DSTV TO DXF CONVERTER“.In this tool, there is an option to provide a bending line in a different layer on the dxf file. The output dxf files contain information in which direction the sheet has to be bent. This information can be used by the detailer and fabricator for quality output. See below image for clarity

At scale, efficient systems of communication and coordination are required in order to efficiently prosecute projects. These systems will likely be of immense value to yourself, and your clients. Consider the following example:
Our critical path sits within the ABCD building, I have run a target date commencing 29/6/22.
Is this possible for the ABCD given the attached review?
What further do you need from us to mitigate any time frames lost?
Can we get ahead on the procurement of the Steel while we look to focus on getting the SD’s to IFC this week with Tek1?
Email received for the ABCD Building.
The critical question: what are the hold-ups for the project?
Likely our client, has no idea, let alone the builder/developer (a large one). Projects are held up in the weeds. The folks at the top of the supply chain need to make resource allocation decisions. Right now, they’re doing so, effectively blind. Or they have to send out emails like this one.
Would anyone remember, what the specific hold up for the project was a few months ago? It’s very hard to remember. And it’s hard to dig it out of the 100s of emails you would have received over that time period. But if you have built up a timeline, it is relatively easy to see what’s happened. All I had to do was to check out our status reports:
Status reports for this project. Details redacted.
As you can see: the project has been in limbo since the 20th of April. It’s self evident. If you didn’t have a timeline, you’d have to bury your head in 100s of emails to retrace your footsteps. We’ve been waiting for this review for three weeks. That’s roughly three weeks ago.
As usual, the reviewers are holding up the show. Except now, given everything is tracked, it’s very hard for them to conceal their inefficacy. Then there were the delays due to: (i) asking RFIs, and (ii) waiting on those answers. (The RFIs are usually asked in the first place, due to the poor quality drawings that are received). The price of inefficient designers (architects / engineers) is monumental. Add poor coordination into the mix, as well as ballooning material / labour costs, and that spells a perfect storm for builders.
Building up a simple status timeline massively improves transparency, improves communication with your client – and all this for very little cost.
