Quick draw

There are a number of techniques that can be used to make the construction of a Model simpler and quicker.

Quick Copy and Paste

Select the items to be copied by pointing to the item and clicking the left mouse button.
Multiple items can be selected by pressing and holding the Shift key while selecting individual items.
Multiple items can also be selected by drawing a selection rectangle around a group of items.
Press and hold the Ctrl key down. Move the cursor within the selected item(s) bounding rectangle and press and hold the left mouse button down. Move the cursor and the copied items to a new location and release the left mouse button.
If you want to do a Quick Copy and Paste of a single item it is not necessary to do a separate select. Press the Ctrl key, point to the item, press the left mouse button, drag the item copy to a new location and release the left mouse button.

The quickest way to draw streams from connector to connector is to do it in two steps.
First, draw the stream from connector to connector ignoring the path.
Point to a connector, press and hold the left mouse button down, move the cursor to the destination connector and release the left mouse button. This constructs a stream from connector to connector.
Second, (with the stream selected) point to one of the stream segments (the cursor will change to the 4-Way cursor) and move the stream until it is positioned as desired.
Moving a stream aligns stream segments with the connectors (i.e. horizontal stream segments will be constructed where the stream is connected to horizontal connectors, vertical stream segments will be constructed where the stream is connected to vertical connectors).

Streams can also be constructed by bumping connectors.
Select an equipment item and with the Shift key down, move the equipment item and bump one of it's connectors against a connector in another equipment item. If the connectors are compatible, a stream will be constructed.
You can also bump a connector in an equipment item against the end point of a stream. With the Shift key down, move the equipment item and bump one of its connectors against a stream end point. If the stream and connector are compatible a connection will be made.
You can also bump a stream's end point against an equipment item's connector. Select a stream and point to a stream segment. The 4-Way cursor is shown. With the Shift key down, move the stream and bump its end point against an equipment item's connector. If the stream and connector are compatible a connection will be made.
