If you're inserting the block into a drawing then the centerline will only display if the block is on layer <none> (that is to say it's not assigned a layer)<br />As soon as you change the layer, the block assumes the properties of the layer. You can at that point override the layer defaults with a different weight, linestyle or color, but it will apply globally to the block geometry.<br />It's Microstation J logic (shared cell). I, myself, wish Solidworks would immitate AutoCAD's Bylayer/byblock functionality for nested geometry.<br />CAD naked<br />John
Can you post block you are having problems with? What version and service pack are you using?
