Thanks for the clarification, I'll be sure to use linked dim's when its needed now.

That is a real good question. Here some great reasons for linking dimensions:

• Using the equal relation works great with sketch elements such as lines, arc and circles but doesn’t work with angles and distances. Any dimensions can be linked including extrusions, drafts and revolves.

• You can reference the linked value from anywhere inside of the model not just in the original sketch. With having a name assigned to a linked value makes it easier to reference the correct value.

• Named linked values lend themselves nicely to formulas. Rather then entering a number value into a formula you can reference the linked value name; i.e. D1@sketch3= “Hole Cutout” + .005. (I plan to cover this more in a later post). If you change the linked value in the dimension the referencing formula will automatically be updated.

Well Tom I hope this answers your question. There are probably more great reasons for using a linked value but I am only on my first cup of coffee this morning. Once again that was a great question…and keep them coming.

Good point. Thats why you are the master and I am a mere padawan. I will be making an ammendment to the post later today. For thos who cannot wait, you can select "Unlink Value" from the same pull down in the Modify window.
