When you point at a parameter name on the Parameters dialog box, a tooltip displays the parameters, sketches and features that currently consume (or make use of) the parameter."holeDia", "filletRadius", "forceOnComp", etc. Another way of writing parameter names could be by beginning the first word with a lower-case letter and capitalizing the first letter of subsequent words that make up the parameter name (a convention adopted by most programmers) e.g.In this case, it is appropriate to use underscores (_) to separate the words e.g. That is, the name " Hole Dia" is not permitted since there is a space between Hole and Dia. If the name of a user-defined parameter is made up of more than one word, spaces are not allowed between the words.That is, "1stDia" is not allowed as a parameter name. You cannot begin a parameter name with a number.These could be renamed but they remain model parameters. Model parameters are usually named d0, d1, d2, and so on.For a particular part, no two parameters can have same parameter name.The parameter name is a unique identifier assigned to each parameter.
The parameters are listed as records (rows) in the dialog box while the Parameter Name, Unit/Type, Equation, Nominal Value, etc are arranged in columns. The Parameters dialog box is shown below: So how can you bring up these parameters and play around with them? Simple! With at least one component opened, go to the Ribbon > Manage tab > Parameters panel > Parameters tool. Parameters that are created automatically by the application as you add dimensional constraints, extrusion height, hole depths, etc are called " model parameters." Those added manually by the user are called " user-defined parameters." Other types of parameters might be added if you use Stress Analysis and Dynamic simulation environments.
These dimensions are parameters and they are named from d0 upwards. SuchĬomplex equations could be found in the designs of machine elements like gears, v-belts, sprockets, fasteners, etc.īy default when you begin a new part, dimensions (I prefer to call them dimensional constraints) are added by you to
As an engineer, these parameters are the data you need.ĭepending on the design intent, you may want to create "user-defined parameters" whose value could be obtained from just ordinary numbers, simple mathematical equations, or complex equations embedded with other parameters. From the first line drawn to the last engineering analysis carried out on a model, parameters are intelligently quot harvested" by Inventor.
So the power of Inventor Professional lies in its use of parameters for controlling the models, so that there is associativity between the model and the numbers controlling any particular feature on a model. Inventor is called a parametric modeler because the sizes of the features and their relationship with each other the relationship of one part to another in an assembly the forces, pressures, and moments applied for stress analysis and the forces, torques, velocity, and acceleration applied in dynamic simulation environment are all parameters! These parameters are actively involved in controlling the shape andīehavior of the part or assembly being created. These features are usually conspicuously listed on the model browser in the order in which they are added to the design (though they can be reordered as long as it does not affect their dependencies) and the features could be modified at any time as long the modification would not be detrimental to dependent features. If you are also experienced with surface modelling, you would likely use features like sculpt, thicken, patch, and trim. So in a design workflow for a component, you would most likely make use of extrusion, swept, lofted, revolved, threaded, hole, rib, fillet, shell, and chamfer features. For avoidance of confusion, Inventor is said to be feature based because each modification to a component is regarded as a feature. Of course, by now, we already know that Autodesk Inventor Professional is a 3D feature-based parametric modelling application. This time we are going to deep into the world of parameters - the engine house of Inventor Professional. Whoa! It is nice writing another interesting article on Autodesk Inventor Professional.
