Documenting 3D Models: Part 4

Documenting 3D Models: Part 4:
When we left off last time, we’d just finished creating three projected views from a base 2D view of 3D model space geometry.

So far, so good. But let’s take this to the next level, and modify some individual views.
When I select the isometric view, I get 2 grips and a contextual ribbon tab.

The two grips are pretty straightforward. The square one enables you to move the view, while the arrow grip enables you to change its scale.

Notice that the default scale is “From parent”, so if you change the scale of the main view, this one will change too. If I set this to a different scale, it will stay the same size even if the parent scale changes.

On the contextual tab, there’s a panel for creating new views—projected (which we’ve already covered), and section and details (which we’ll cover later). You can also manually update the view, if its source geometry is modified.
Edit View brings up yet another contextual tab.

Note that it looks a lot like the Drawing View Creation tab, with many of the same tools. The special icon above Hidden Lines indicates that the view style is controlled by the parent view.
I’ll change this isometric view to Visible Lines, 1/16” scale, and move it to be more in line with the other views:

One last note about grip-editing projected views before we wrap up for today.
By default, projected orthogonal views are constrained to align with their parent view. This makes sense, as this kind of alignment is generally good drafting practice.
But if for some reason you need to break the alignment (maybe your views won’t fit on the sheet without it), it’s easy.
image
Just press Shift after you’ve made the Move grip active to switch to free motion, and press it again to switch back to normal alignments.
This only applies to orthogonal views (top, bottom, left, right, etc.); since isometric views don’t have axes to align to, you can always move them freely.
See you next time!
