BEST PRACTICES IN AUTODESK INVENTOR 25
◆ Part creation workflow that is easily understood by other people, should editing be neces-
sary in the future
◆ Practicing restraint in creating large numbers of duplicate features, when identical features
could be combined into a single feature
◆ Adding details later in the design, creating fillet features instead of adding them to
sketches, and adding fillets at the end so a change to fillet won’t cause a failure in a
downstream feature
◆ Developing a good workflow that will be repeated in future design projects, providing
consistency and design, and helping others to understand and follow good design
practices
One issue that AutoCAD users struggle with is complex sketches. A sketch should have only
the geometry necessary to create the feature. If a sketch has more than eight to ten elements, you
should try to split it up into smaller sketches.

Many new users do not understand the importance of having fully constrained sketches. It can be
highly frustrating to have a model fail when you make a simple change, all because a sketch was not
properly constructed.
Developing Assembly Structure for Maximum Efficiency
Developing an efficient assembly structure is essential for success and maximum performance in
the 3D modeling environment. Poor assembly design will plague the design process throughout
the entire life of the job, often creating large assemblies that cannot be rotated for view, cannot be
used to create 2D drawings, or often break down, requiring many hours of repair and constant
attention.
You can avoid the nightmares of poor assembly design structure with the proper use and
understanding of how assembly files work. A properly designed assembly structure possesses the
following qualities:
◆ A top-level assembly will be composed of numerous subassemblies constrained to one
another. The use of individual parts within the top-level assembly should be limited.
◆ All components within a top-level assembly must be properly constrained to one another
so that they will move or not move as they would in the real world. All adaptive compo-
nents should have adaptivity turned off when adaptivity is not required at that particular
moment.
◆ By limiting the number of components at the top-level assembly, the number of 3D con-
straints present in the top-level assembly will be limited, improving overall performance.
Note that when we say component, we could be referring to a part file or a subassembly file.
◆ Properly created and named design views and/or level of detail (LODs) should be present
within the assemblies and subassemblies of the design. Use of either or both will provide
flexibility and improve performance in the assembly design as well as the 2D documenta-
tion process.
