BIM MODELING SERVICE FOR MANUFACTURERS
Our office located in Israel in the Upper Galilee region, and our team consists of modelers and engineers from different disciplines. What we have in common is our belief that BIM is a fantastic tool, the software is becoming more user friendly, and the process is essential for the construction industry.
We focus on BIM object modeling for manufacturers. Revit family service or BIM object modeling service.
As the world moves into a more efficient way to design buildings and constructions project using BIM software like Revit \ Archicad \Tekla Structures, the request for fully parametric elements from different manufacturers is rising.
The ones that we're smart enough to supply those objects, already enjoying the benefit of being part of many BIM projects. their digital models (families in Revit) are implemented and appear in schedules \ bill of materials.
Our modeling focuses only on fully parametric BIM elements. As our team has a long history in different BIM software, we know the real difference between "junk" 3D models to fully parametric ones. A 100% parametric family contains underlying geometry that designed in such a way, so the whole series supplied as one file. The parameters in the geometry refer to different dimensions of the object. Windows parameter for example: Height=900mm, Width=1200mm, Depth=120mm and so on.
In real life modeling of a parametric object, there are dozens of parameters to each. Our team needs to make sure that while changing one parameter, it does not conflict with all the others.
A window manufacturer shows in their pdf catalog, different dimensions for a window with the same 'general appearance'. From our end, we need to make sure that when the user clicks to change the desired member, the geometry changes immediately without any conflict and errors. in Revit, those members called "Type".
Don't panic from the different words used in different software. They are all describing the same. Parametric 3D models!
As the BIM process evolved through the years, additional data besides geometry has been added to the object. This called MetaData. manufacturers share text data regarding different properties of the object. things like "weight", "Warranty", "Manufacturer website (url)", "Installation PDF" and much more.
The metadata is endless, so it's more about focusing on the essential things the manufacturer wants to share with others. The BIM object of the product is the digital tween to the product in real life. The product has what generally described as a "life cycle," so anything related to that can be implemented as metadata.
Advanced users are very familiar with different sites that give access to millions of objects for different manufactures. Sites like bimobject.com revitcity.com and more.
?Ok. I am a manufacturer. What's next
1) collecting the info about the products planned for modeling. This stage seems to be a burden for many small manufacturers. The data about the product series isn't organized, although products are on the production line regularly. The geometry data sometimes lost. Different data buries in different departments. Some products have digital data (pdf), while others have hand-drawn sketches from years ago or lost. Some manufacturers are outsourcing the real production of products to a sub-contractor, which he is the only one who has the geometry data. In the end, the more organized the data arrived at us, the easier and shorter the process is. This stage is at the full responsibility of the manufacturer, and we don't have a way to skip it. We can contribute to the process by sending the manufacturer and appropriate PDT (Product Data Template) to fill in (a cloud-based sheet, of course).
2) Deciding on a "standard" for the "family" modeling. Like any other field, there is no gold standard for "how to create a 3D BIM object". So the metadata we talked about earlier can be organized in endless forms. In the UK, there's a mandatory use for BIM in public projects, so they created a "standard" for more than 5700 product types. Check out https://toolkit.thenbs.com/.
Even if you are not targeting the UK as a customer base, I still suggest following a standard. The world isn't going back, and data should be organized quickly and shared across different countries. Another used standard is COBie.
This stage is something we agreed on together after understanding the target audience and countries for marketing.
3) Modeling of the parametric 3D object +Meta Data. In Revit, we create families with different LOD (level of detailing) to make the works faster. LOD is a visual approach to present the project at different stages. i.e. schematics> prilimnary> details design, etc.
more about LOD here.
4)Quality control. Each object \ "Family," is tested multiple times while checking for conflicts, bugs, and errors regarding the information on schedules. In Revit, different elements have brilliant features that need a thorough test. For example:
Windows 'sticks' to walls.
Pipe fittings populate on suitable pipe diameter.
Doors have open \ close mode.
Air-condition units create voids.
5)Delivering the object (the deliverables are files) to the manufacturers. The manufacturer decides where to host the files and how to grant access to users around the world. Some manufacturers prefer to host on their home sites, and some others share the object through different hosting sites like bimobject.com. The 2nd option is more expensive but opens greater exposure. (Which not always leads to more sales! That said, ill keep this subject to another article)
6)Maintaining constant communication with the manufacturer regarding new updates of their products, thus doing the required updates to the 3D models and keeping the shared data up to date with clients.
