How do I measure containment?

You can measure containment using a mix of the following:

How can I make measuring containment easier?

There are a number of workflows that make measuring containment easier and more efficient:

  • Naming conventions.
  • Colour conventions.
  • Power search.
  • Selectively showing measurements.
  • Measuring vertical runs.

It’s also helpful to think of containment in terms of “systems”, which include the linear lengths and also the components (e.g. bends and tees) that go along with those lengths.

Naming conventions

Because measurements are listed alphanumerically, and so each item is grouped together with other components of the same system, it’s helpful to reverse the descriptions so you have the common word at the front 

For example:

  • Tray - 300mm - Power
  • Tray - 300mm - Power - Bend
  • Tray - 300mm - Power - Tee
  • Tray - 450mm - Power
  • Tray - 450mm - Power - Bend
  • Tray - 450mm - Power - Tee

By naming your measurements in a deliberate way, you can ensure firstly, that all different sized tray is grouped together, and then secondly, that all the components from a specific sized tray is grouped together.

Colour conventions

So you can easily see which measurements relate to what system, using the same colour for all measurements within a system is generally a good idea.

In the example above, all the 300mm Tray is blue and all the 450mm Tray is red, which then makes it easier to visually see the whole system on the drawing, including all its components,

Power search

Provided you have used the deliberate naming conventions covered above, you can then use the power search field (Shortcut = F) to filter your measurements down to specific ones you care about.

In the example above, by typing in "Tray - Ltg - 225", anything not related to that containment system is filtered out, leaving just the items that matter.

Selectively showing measurements

Building on the colour / naming conventions and power search use covered above, you can then selectively show containment systems you want to check or work on.

  1. Toggle all measurements off.
  2. Use power search to filter measurements down to the ones you care about.
  3. Use the check boxes to the left of the measurements to selectively toggle back on each measurement you care about. 

In the clip above, you can see that first the 50mm Basket is selectively shown, followed by the Dado trunking.

This can be especially helpful on drawings with busy containment schemes or for verifying accuracy.

Measuring vertical runs

You can measure vertical runs in two ways:

  • Creating a separate manual count measurement.
  • Adding an equivalent horizontal measurement.

Creating a separate manual count measurement
Similar to using the manual counting tools to allow for bends and tees, you can also add manual points to allow for vertical runs.

  1. Copy the existing containment system’s name to your clipboard (Shortcut = Highlight & Ctrl + C).
  2. Create a new measurement.
  3. Paste the containment system’s name in as the name for your new measurement (Shortcut = Highlight & Ctrl + V).
  4. Add a suffix to describe the vertical allowance (e.g. “Riser (Allow 4m)”)
  5. Ensure your measurement is set to “Point”.
  6. Add a manual point to the drawing for each vertical run.
  7. Change the colour of the measurement to match the rest of the containment system.

Adding an equivalent horizontal measurement
Because linear measurements can be added anywhere on the drawing (IE: they don’t necessarily need to be drawn over the top of the containment actually shown), it’s possible to add additional lengths to account for vertical runs.

  1. Click on the linear measurement relating to the containment system you need to add vertical runs to.
  2. Off to the side of the drawing, add a length for each vertical run you’re adding.
  3. Take note of the displayed meterage as you draw the line and stop the line when it equals the metre allowance you want to make.
  4. Repeat steps 1-3 for each vertical run you want to add.

In the clip above, you can see two vertical runs for each riser need to be allowed for, and to this end, two 4 metre lengths, are added off to one side of the drawing.

These 2 x 4 metre measurements are then added into the total amount of containment allowed on this specific drawing.
