Know the Difference between Fix and Default constraints in CREO Parametric Assembly Design

In this Tech Tip, we will explain about the difference between 'Fix' and 'Default' type constraints in Assembly Design using Creo Parametric. Apparently these two types of constraints look similar as they both make the model fully constrained, but we will see two examples wherein we can understand the distinct difference between these two constraints.

In Solidworks, we can add constraints and also fix the component without modifying or deleting the existing constraints. How do we do that in Creo?

[@myigetit]

In PTC Creo, you can fix a component or add constraints in a similar way to Solidworks. To fix a component, you can use the "Pin" constraint. The Pin constraint locks the component in place, preventing it from moving in any direction. You can add a Pin constraint by right-clicking on the component and selecting "Pin" from the Constraints menu. To add constraints, you can use the "Constrain" command. You can select the components you want to constrain, then right-click and choose "Constrain." This will bring up a menu with different types of constraints you can apply, such as coincident, parallel, tangent, and so on. Once you have added constraints, you can modify them if necessary. To modify a constraint, right-click on it and select "Modify Constraint." This will bring up a dialog box where you can adjust the parameters of the constraint. It's worth noting that in Creo, constraints are automatically solved and updated as you make changes to your model. This can help ensure that your model stays in the desired configuration even as you make design changes.

@@myigetit I do understand how to use the constraints in Creo but I could not find a similar way in Solidworks (which is very convenient) to fix a component without disturbing the existing mechanism/constrains.

@@allanjlansangan There is a fundamental difference between Assembly environment in Solidworks and Creo. In Solidworks, we call the component in the assembly and if we place it randomly at any location in the Assembly graphics window, then the component gets fixed at that location. This is similar somewhat to the 'Fix' constraint in Creo. Further in Solidworks, if we need to move or rotate the component, then we can toggle the Float option and Fix constraint gets disabled releasing all DOF. After moving/rotating as per our need, we can fix the component again. When the component is in floating mode, we can create an Origin to Origin type Mate constraint which fully constrains the component and that is similar to 'Default' constraint in Creo.
