![]() ![]() When you use this, the second UCS you select will be the one to move to the location of the first one selected. To use a UCS-to-UCS constraint, use the Constraint Set tab within the constraint dialog box. This constrains the 3 axes and the point of the two coordinate systems. Within Inventor assembly, a UCS can be used as a constraint that restricts movement in all directions. Using a UCS within an Inventor assembly as a constraint Constraining parts In the image below, a hole was placed on the edge of a round surface at a skewed angle. Once a UCS is placed, you can use its reference geometry as a reference for your hole. One example of a UCS use at the part level is with the hole feature. ![]() You are also able to directly type in the value to the dialog box. The delta for the movement will be indicated in the dialog box. Your mouse pointer will indicate the movement depending on where it is when you start dragging. These parameters are helpful when moving your UCS.Īnother method to move a UCS is to select it either in the model tree or in the model, then dragging with your mouse on the axis to rotate or translate it. Having the 6 parameters is useful when using them to define features and to move parts after being placed. These are in reference to the orientation and point it is placed at (by default this is in reference to the origin point and orientation). Each UCS creates 6 parameters, 3 translational and 3 rotational, in relation to the point that it was placed.Įach UCS is associated with 6 parameters to move it or rotate it. A workaround for placing a UCS without having defined the x or y-axis is to right-click on your mouse and select finish. ![]() If you set the UCS in space, it will be referencing its relation to the origin. You will be asked to select this x and y-axis afterward from two points. This point defines the origin of the UCS. Upon selecting the UCS feature, you are prompted to place it on a point. Placing and Defining a UCS – How Inventor professional can be useful within a part The Inventor UCS feature allows professionals to use the same definitions as the origin on your part features and assemblies. The origin is assigned 3 planes, 3-axis, and a point that can be referenced throughout your file. ![]() The origin within an Inventor assembly or part is a feature not often thought of. How To Use Custom User Coordinate Systems (UCS) with Inventor Assembly for Inventor Professional ![]()
