is it possible to dimension the center-line of a hole to reference planes?

[Anonymous]

i am adding a hole to a model. i want to add locating dimensions to reference planes not to model edges.

Is this possible?

I see if I add a reference plane and select the center-point of the circle a coincident relation will be added between the reference plane and the center point.

I hope I do not need to create a lot of reference planes to locate features

Also how do I lock the dimensions so they cannot be dragged. i.e if I want to drag the hole I do not want the hole to increase or decrease in size

Also can the dimensions be locked so that when i exit the sketch and then go back to edit the sketch I want the dimension to still be locked.

Every component has its own origin (which may or may not be in the same location as the main origin).  Any sketch in the component can use the component's origin or any other component's origin for its dimensions.  Although, I don't think it would be a very good practice to use another component's origin.  Usually, you'll need to reference the origin in order to fully constrain a sketch.

Dragging geometry that isn't fully constrained can change its shape.  The move command is usually better to use than dragging with the mouse. Editing dimensions is even better.

The Fix/Unfix command will lock geometry in place, but doesn't prevent it from being changed by some operations like fillet.

You can lock a hole to a feature where you set its dimension from a position on the model, if you need to change it, you go back in the timeline to do it.

You do this so you can edit feature at the feature level in question at a local level, not at a global level what can make it go sideways fast.

What is just move the timeline to the feature then edit it, to set its position in stone?

Most things in fusion need a refinances from to maintain a local and global reference.  Rule one covers this.

Doesn't sound like you've done any of the tutorials as these are very basic questions. Try doing the hands on exercises in the help on sketching.

I've "struggled" with the hole references too, having used other CAD platforms that any feature can be ref'd to the origin plane(s).

The way I've found to do it is to create a sketch circle first you can dim to the origin point then create the hole feature referenced to the sketched circle.

You can't reference or dimension from a Plane directly.

Instead, within your Sketch that includes the hole, you can Project a line where your desired Plane intersects the sketch plane/face, and then dimension your hole from that line.

Purple line in Sketch below is the result of Projecting the Plane.

If you use the hole tool and the object is constrained to the origin you can dimension to the edges that are alined to an origin plane, just not to the center of the origin or the origin plane.

In a sketch, you can dimension to the origin center along a plane not on to the plane. 

Any other plane what is in the post above this one.
