plotting blocks

[peterbird]

I have been using autocad 2000LT for 18 months successfully, but I have recently encountered a problem plotting architectural blocks as supplied by Medp. All new drawings will not plot the blocks though old drawings still do. Obviously I have altered a setting by accident. I can see the block in paper and model space, but it does not print nor does it show on print preview. Any thoughts?

I reckon you have your blocks on a layer that is set to not plot.Have a look in the layer properties manager and see if the plotter symbol for the layer that these blocks has a little red line or red circle over it.Just click on it again to allow this layer to plot.

Cheers for the suggestion, however the layer is set to plot, and other lines drawn in the same layer still plot but not the blocks themselves, even if i change the block layer they still refuse to plot.

maybe change the colour of the block,your plot style may see it as to light of a colour or check your plot style table so that it reads and prints all colours as black!

The layer a block is inserted on can be different from layers that objects are on *within* the block...have you checked both kinds?

[peterbird]

thanks Kate, you were right I had turned off layer 0 which though it is not the layer the block appears in, once exploded the block defaults to 0 proving as you say that blocks and the elements that they are composed of can be in different layers.
Cheers for all your suggestions
