Hello,

If you can snap to its edges with sketch lines on the view, then draw these lines as construction lines.

Hide the plane.

I'm not in front of SW at the moment, but this is what I would attempt.

Cheers,

Kevin

Like Kevin, I don't have access to SW right now,  but I agree that placing a sketch line and making it coincident with the plane would be pretty simple.

Hello,

If you would like more control over these lines than just "centerline", then keep the lines as "regular" lines.

Then create a new layer (appropriately named) and move them to it.

On their own layer, you can control linetype, thickness and color.

Even if you stick to just centerlines, the added layer method may be of greater benefit as what you are doing may be more apparent to others.

Plus it's one story for everyone, if a similar need arrives for some other entities on this or another future drawing.

And by temporarily turning off all other layers, you can easily see what is where on this layer (and quickly remedy any technical boo-boos by moving them back to thier rightful layer).

Just another serving suggestion.

Cheers,

Kevin
