Stage 4: Create Kerbs
Edges are often created using the Loft compound object instead of a simple extrusion to take advantage of the loft mapping parameters. The Loft mapping parameters enable kerb or brick materials to follow the curves of an edge as they do in the real world. In this example a kerb is created using Quickscape Edge Path and Quickscape Edge Section. Format: Text/Image

AutoCAD Productivity
Possible Solutions to the Disappearing Drawing
From: AutoCAD Productivity Articles #142
Originally published: October 2015
Many of my customers encounter a situation where the drawing disappears when they change the view or use Zoom Extents. Here are a few of my suggestions that I'm beginning to include in all my training sessions:
Purge and Audit a drawing you inherit or haven't worked on in a while. In the Purge command, if the two boxes under Unnamed Objects are ‘live’, check them both.
Save the current layer condition as a layer state, then turn On and Thaw all layers. Objects that are on layers that are Off are still ‘seen’ when you Zoom Extents. Saving the layer state will give a fallback position, just in case.
Set the QTEXT (Quick Text) feature to ON, then Regen the drawing. Turning on Qtext will replace all text objects with boxes and may make the dots around the perimeter of the screen easier to see. This feature was used extensively in the early days of pen plotters when it just took too long — albeit very entertaining over a lunch hour — to plot drawings with a lot of text. Instead of pppllloootttiiinnnggg out each letter, it just drew a quick 4-sided bounding box around the text. (Set QTEXT back to OFF when you're finished.)
Set PDMODE to 35 to display Points in the Circle-X format. All my furniture/facilities customers have drawings with Point objects on the insertion points and other vital locations on their furniture. Setting the PDMODE — Point Display Mode — to 35 makes any floating Point object visible. (Set PDMODE back to 0 to go back to the default condition of dots.)
After all's said and done, hopefully you will see the misbehaving object that's keeping your drawing from displaying as you expected. At that point, you can either move those objects back among their peers… or simply delete 'em. That's your call, but at least now you know what that problem was!

Tip of the Day
Mid Between 2 Points (m2p)
Sometimes you might want to find a point midway between two other points. In the past, you might have drawn a line between these two points and then used "Snap to Midpoint" but this requires the drawing of a construction line and isn't very efficient.
Enter the m2p object snap. This will find the midpoint between any two picked points without the need for a construction line.
How it works: Say you want to draw a circle midway between two squares, start the circle command and then enter "m2p" when prompted to specify the center point. Now just follow the prompts.
Command: circle
Specify center point for circle or [3P/2P/Ttr (tan tan radius)]: m2p
First point of mid: (pick first point)
Second point of mid: (pick second point)
Specify radius of circle or [Diameter] <20.000>: (pick to complete circle)
