Hello
What is the proper way to verify the component slected in the schematic caputure has the proper foot print associated with it?
What is a package type DSC, and MISC.
Is there a way to open the PCB symbol from inside the schematic capture app to verify holes sizes, pad sizes, and spacing?
Is there a description view of the component foot print that shows dimmensions?
Thanks

As you add the component, there's a 'Preview' check box in the dialogue window that lets you see the footprint linked to each package type. Once the component is in the design, there's no way of checking directly. You can either use the preview option in the Library Manager, or use the Databook.
For the library manager, go to [File], [Libraries], click on the 'Components' tab, change to the right library and click on the component name. The top box lists the symbols linked to each package type. If it's the default package, the preview will show it, otherwise you'll need to change to the 'PCB Symbols' tab and browse for the listed symbol to see a preview.
For the Databook, go to [File], [Databook], and browse in the left hand pane for the correct component library, then component. Scrolling through the right hand pane then lists all the symbols used, including graphics of them. Double click on a symbol to switch to it within the databook, then you can check the dimensions. Other than editing the symbol, that's the easiest way to check the dimensions.
DSC is an mnemonic for 'discrete'. 'MISC' is just miscellaneous, for when the other package mnemonics weren't appropriate, or had already been used. Earlier versions used to restrict the list, but you can now create your own mnemonic for package type.
There's no dimensioned view of footprints outside the databook. See above.
