My first Revit project





Well, i've finally started using Revit A rchitecture after all the hype BIM has created in the construction industry. I have to say that it is pretty similiar to Archi CAD, which i've worked on before. However Revit, has many more features to boast about, many of which i've just started exloring.

My first project on Revit is my residence in Kerala, India. It is an approx 2000 sq.ft villa. It is made with masonry walls and sloped roofs. It has a small garden with appropriate setbacks on all 4 sides and 2 balconies, one facing the front side and the other facing the rear side.

I first went ahead and imported my Auto CAD drafted plans into Revit in the respective levels of plinth level, first floor, second floor and roof level. Then i drew property lines around the residence and extruded it to form the toposurface. Once i had finished making the building pad, i started making walls and floors. Soon i made a sloping roof over the ceiling slab of the second floor.

I added the appropriate doors, windows and furniture to the plans. Once i had applied the appropriate materials to the individual components, the building was ready.

Next i went ahead with parametric modelling. I decided to create a sunshade for all the windows which would change in length with respect to the window's width. For this, i had to first create a family with the sunshade. So i opened a Generic model family and designed the sunshade using reference planes in the x,y and z axis and then extruding a solid rectangle to form the sunshade.

Then i went on to load this sunshade(family) into the casement with trim window (family) that i had opened from the existing revit files. Once i had aligned the sunshade above the window in various views to the exact point i wanted, i created 3 new parameters namely, sunshade length, breadth and depth in the parameter's page that opens if you press the types tab under the manage tab. Then i selected the sunshade and went to element properties>type properties where i linked the sunshade length with window width using the associate family parameters page.

This fixed the sunshade length with respect to the window width. I had to create 2 more parameters, distance from the left side of trim to sunshade and distance of window from sunshade level before i could finally complete the parameter requirements.

When i finally loaded this casement window with trim and sunshade into my project, it worked perfectly by having the sunshade length and window width changing with respect to one another.

Finally i took one exterior rendered view and 2 interior views to give a realsitic idea of how the project would look after completion.
