Move Main, Move Line, Erase Main, and Erase Line

These four commands really make it easy to modify drawings. Move Main and Move Line have different options, but Erase Main and Erase Line work the same as each other.

Move Main

Move Main can be used to move your main over just a little, or over a lot. It can even be used to move the main to the other side of a head. I will do that with the main below, which is zoomed in for clarity.

I pick Move Main and am given the following options:

Coupling Segment will ask you to select the main pipe, and will find the pipe between the nearest couplings. Only that segment will be used. Straight pipe run will move all main pipe in the same orientation as the pipe selected. If the main changes direction, it will be selected only up to that point. You can pick the shaded option with the mouse, type in the colored letter, or right-click or press Enter to get the Straight option, which is the one I am doing, here.

I pick the main and am then given two options, below. I can just pick a point on the screen to plop the main down, or I can right-click to choose the Direction then Distance option, which I do

I am then asked to pick a point to show which side the main is being moved to (kind of like the Offset command). I pick 'north' of the main. Distance is not (yet) important

Then, I enter the distance. I choose to type in 12' and press Enter. The main is then moved:

Move Line

I want to move this line over to the left one foot

 Move Line gives you three options, below. The first does an entire straight run of branch line, the second does one side, and the last does the same as the Move Main Coupling segment

 

If I pick Straight pipe run by clicking on it or right-clicking, I am asked to pick a line, which I do:

Then, just like the Move Main command, I pick the line and am asked to just pick a point on the screen to plop the line down, or I can right-click to choose the Direction then Distance option, which I do

I am then asked to pick a point to show which side the line is being moved to (kind of like the Offset command). I pick one side of the line. Distance is not (yet) important

I then put in a distance of 12

A question unique to Move Line is whether the heads should be moved with the line, or left where they are. The default is to not move them (No), and that is what I go with

The branch line is moved and armovers the the heads are created in the proper layer!

Note: Moving the line back 12 inches would remove the armovers

Erase Main and Erase Line

These two commands work essentially the same way as each other, with the additional option of One Direction (explained above) for the Erase Line command

Picking the main removes it, and the connecting riser nipples:

Erasing a line leaves the main and removes the riser nipple (if present) and reconnects the main

Does this command work with pipe at odd angles? Every time I try to used with piping running at non-right angles it seems to freeze the program.
