How to create great 3D models
There are several possibilities for starting a 3D project. We may:
• Create a 3D project from a complete set of 2D drawings, with all the ne-
cessary views included. Here, we don't have to project or idealize; we just
have to decide the best approach and the commands that are to be used.
• Create a 3D project from a plant view and some other elements. Here we
have to project a lot and probably have to study several possibilities in or-
der to find the most suitable project.
• Create a 3D project from scratch. We have nothing except some condi-
tions about space, functionality, or others.
For any of these possibilities, the keyword is planning.
First, we have to carefully plan the work. Instead of immediately starting to model, it's
better and less time-consuming to decide a draft sequence of tasks.
Some important questions at this phase:
• Do I have access to something similar?
• How complex will my project be?
• Do I have some 3D blocks that I may use?
• Have I created the needed layers and other definitions (layouts, styles, and
so on) in another project?
• Am I going to use external references in my project?
• Do I have all the necessary information?
If we have 2D drawings, these must be carefully studied, especially if there are any
inconsistencies between views and how to start.
Next, we set up our model. We can open the most important 2D drawing and save it
with a different name; we can start a drawing and insert the other drawings as blocks
or external references. We must verify if units are coherent, by applying the UNITS
command.
