Whatever you choose, if you're new at CADD, a bit of advice:
1. Rough out your work quickly all on one layer, by drawing 1 each horizontal and vertical line, and then offsetting them and trimming them later. You can get the actual material sizes as well as the gaps between if applicable. Add a "placeholder" hatch to your work for now, although all hatches will look the same for now.
2. Draw your models at 1:1 in modelspace, and arrange scaled views of them on your layout tabs -- the tabs will be 1:1 but the viewports can have differing viewing scales assigned to them.
3. Test out layers, linetypes and hatches in paperspace (layout tab) to verify the look of the plotted work. For the hatches, this is how you scale them to look proper at 1:1. Then you can use CHSPACE to send them through a viewport into modelspace. Make the hatches annotative, and use the Property Manager to add the scales you anticipate using them at (such as 3"=1'-0").
4. In modelspace, set your CANNOSCALE to match the scale you might normally draw your detail on a drafting board, such as 3" = 1'-0". This is the list of scales found on the taskbar at the bottom toward the right.
5. When your model is ready to make more finished-looking, use Property Painter to change the properties of your draft model, to match the new linetypes, lineweights and hatches you brought in from paperspace. Once you have the basics set up and one model finished, you can do the quick draft and property painter thing all day long, one after another.
