My Revit experience

I previously dealt with some issues regarding the use of Digital Project. These problems arrose mostly because CATIA is not suitable for the AEC industry. Even if Digital Project is adapted to the building construction techniques, the main core, CATIA, is still a product aimed at industrial products.

Furthermore, Digital Project needs large resources both in time and money for designing anything. It can be perfectly acceptable for mass-produced objects or very complex building, but when it comes to more average construction projects, we have to find another solution.

I was wondering if I would be able to create all the precast pieces of a stone-like facade on Revit, and see what differences we can find.

Here is a little demonstration of concept for designing intricate geometry and casting drawing in Revit

Designing a specific part with the basic tool from the Revit family (extrusion and boolean operations) is not very difficult, and I quickly got the design of one of the arc over the door.

Anyway, some limitations already appears. Due to the void form created as boolean, it is impossible to merge the arc with the superior part, and a join remains.

Furthermore, there is at least one piece I was not able to draw properly a double-curved arch.

I insert my Revit family in a new project, and add a few dimensions and a section line.

A main problem appears when I am trying to extract a section of the curved part. If I get the section, I cannot add dimensions to it.

Finally, there is no embedded tool for extracting the position of the center of gravity. This information can probably be extracted using another software or the API, but we are seeking for a process developed entirely with Revit.

All these limitations made me think that Revit is not powerful enough to efficiently design intricate elements. Even if possibilities for creating complex 3D models are enough for most of the precast elements, there are still too many limitations for using it in production. I am waiting for the next releases of Revit to overcome these issues.

One thought on “My Revit experience

  1. As far as doing anything in any software goes, one requires a lot of knowledge of the best practices. Whatever that can be done in Revit can be done in DP too, in the same amount of time. A few things that come as a standard feature in DP is not available in Revit and vice versa too. Based on the user needs, there has to be some customization. Till date Revit cannot talk to Excel without buying an add in, which is standard feature in DP. Revit is extremely slow for large models, whereas DP is extremely fast. Just that the masses uses Revit, there is crowd sourcing and better shared experience.
