This is ideal for adding features to a component that changes based on the model or version of that component. We can add a bolt hole pattern to the mounting plate using an array, link its parameters and then use them to modify the pattern. BricsCAD arrays can be parametrized in the same manner as 3D constraints, where modifying a linked parameter will change a property of the array, such as number of elements and their spacing. For example, if the “Length” parameter was made so small that two adjacent fillet surfaces touch, the Distance constraint governing the width will lose its references and will either be unresolved or deleted.Īnother feature of parametric modeling is the use of associative arrays. Keep in mind that changing a parameter associated to a 3D constraint performs a direct edit to your model and may cause some dependencies to break. To observe how the parameter’s value affects the geometry, right-click a parameter and select “Animate”.
The radius of the fillets can also be parametrized by giving each circular face a Radius constraint and assigning it an additional parameter. After extruding this object, its dimensions can be parametrized by adding two Distance constraints between opposing faces and attaching their expressions to parameter values, appropriately named “Length” and “Width”. For example, below is a model of a mounting plate. Using this feature, we can easily design dynamic parametric components. As the parameter value is modified, the relevant geometry is updated. A parameter is a user-defined or dependent value that can be linked to a 3D constraint. One of BricsCAD’s unique features is the incorporation of parameters into a 3D model.
