Can never understand people who draw in paper space, its crazy.
Set up a drawing sheet, titleblock whatever you want to call it in paper space at 1:1 then draw in model space at 1:1. Then draw a viewport and change the scale to suit the drawing size.
For example: An A1 titleblock/drawing sheet with a ground floor of a house drawn at 1:1 in model space. Draw a viewport in paper space and change the scale to say 1:50. Perfect. All your dims will be perfectly scaled and it wont look mickey mouse
Solidworks and Pro/E are both good bits of software. I favour Pro/E as its more intuitive. Solidworks is great for nice pretty renderings the easy way
that how we do it too, i work for an architectural practice, we have a couple of people who work in model space e.g scale the title block etc to "look right when plooted but it makes everyhting different if you suddenly have to do an A2 etc. makes it a real pain in the arse when you have to plot it too as its just not as simple as pressing plot e.g you have to draw a window then tell it to scale etc what a load of b****cks!!
i draw everything @ 1:1 scale in model space e.g if you were able to get inside my model it'd be full size.
then we have A1, A2 and A3 company templates already made up which is what i select before i even start drawing, then if i find i need a new different/same size template i just import one.
then go to my paper space template draw a viewport then click in it find my drawing etc and scale the viewport, so quick and easy to set up drawings trust me
the beauty of doing it this way is that i can draw for example a 2 storey house e.g 2 floor plans with everything on e.g all electrical notes and symbols and structural info etc, then i can have simply have one paper space tab for my ground floor plan and one for my 1st floor plan etc then another one for my ground floor electrical and so on.
the trick bit is within each viewport on the different tabs you can turn off particular layers but only in those viewports for e.g electrical viewport i have the electrics turned on, in my normal floor plan i have them turned off etc.
it just make sit very quick and easy to creat alot of drawings for not much effort and it keeps the drawing size down too.
i have a friend who works for an architectural practice near me and they use xrefs, now i understand they are a whole new beast :S
