Contact sets require physical contact with other components to determine the limits. A constraint with limits is identified in the browser by a +/- symbol.
The Resting Position uses the value specified in the Offset box. You can specify a Maximum, a Minimum, and a Resting Position for a constraint in the Assembly tab. The actual purpose of the Constraint Limits is to specify the range of motion for the Components that move or rotate.įrom the Autodesk Help File: What are constraint limits? Constraint limits use the specified values to define the allowable range of motion for components that move or rotate.
PLEASE NOTE: This is a trick that I use within Inventor for examples that I have shown above. A close-up view of the holes will actually show that the holes are eccentric: In the Model Browser, the constraint is shown with a +/- after the constraint to show that it has a Limit to it:Ĩ. I click apply and the constraint is applied.ħ. 005 in difference between the two parts:Ħ. To fix this, I add a limit to my constraint to allow me to override the. If I try to constrain the two axially mates first, I receive the error because my dimensions are off by. I create two axially constraints with the holes and a standard Mate-Mate with the top of the mounting plate, and bottom face of the bearing:Ĥ. This is where I can use the Constraint Limits to override the non-matching values.ģ. If I try to constrain the two parts together, I will receive an error because the dimensions are not the same. The mounting plate I created has a center distance of 4.375 in. It is quite common for parts on the internet to be rounded to only two decimal places.Ģ. I downloaded a pillow block that has a center distance of 4.38 inches. The following trick I use is a Pillow Block, downloaded off the internet, and a mounting plate that was modeled in Inventor constrained together with the different dimension values.ġ. Likely, the dimensions are just slightly off.
When you are trying to constrain two parts together, why does the following error dialog box pop up? Posted on Jby Bob Reid, Manufacturing Solutions Engineer: Error: Autodesk Inventor Professional – Place/Edit Constraint
