You have to read up on "Model Space" vs. "Paper Space".
Any AutoCAD text will be close enough to help you.
Basically, you build the model, full size, under the "Model" tab.
Then you derive drawings of it, on the "Sheetx" tabs, using "viewports", which look through the sheets at the model, and can be individually scaled and individually have model layers suppressed or displayed.
The learning curve is not fun.
Here's a little help with Draftsight:
Assuming there's a model in the model tab, click on a sheet tab.
If the Properties box is not visible, click Tools Properties.
Click on the edge (default) Viewport.
In the Properties box, scroll down to the viewport scale selector, and select a scale.
Then you can grab the corners of the viewport and shrink it around the model's image.
Click the viewport edge again and you can move the viewport.
Then View Tiles 1Viewport lets you define another viewport.
You can probably take it from there.
