Work with check system tools

00:05

To ensure the integrity of the data within mechanical systems.

00:09

First,

00:09

the integrity of the physically modeled system has

00:12

to be checked and any issues rectified.

00:16

In the following example,

00:17

we will review potential system issues within

00:20

the project by assessing associated warnings,

00:23

then investigate and resolve problems including

00:26

physical breaks and system errors.

00:31

Ensure the current view is set to H VAC floor plans. One mac

00:37

modeling errors in duct and piping networks will have

00:40

an effect on the information within a system.

00:43

Incorrect system information will also have an effect on

00:47

the outcome when using duct and pipe sizing tools.

00:51

The check system tools are found on the analyzed tab of the ribbon

00:55

start by selecting show disconnect.

00:59

Then from the list

01:00

check duct and pipe

01:05

disconnects are indicated by the yellow warning triangle.

01:09

Some of these may be due to connections to equipment that still need to be addressed,

01:14

but some may be as simple as a missing end cap

01:21

or maybe some broken flex duct and can be resolved quite simply

01:29

finish by turning off the show disconnects for duct and pipe.

01:35

Once you're satisfied,

01:36

the disconnects have been resolved using check duct systems and check pipe

01:41

systems will highlight any additional or maybe less obvious errors found in the

01:46

systems that will need to be addressed before going on to take information

01:50

from a system or to use the duct and pipe sizing tools.

01:56

Select check duct systems from the ribbon.

01:59

Here we see two areas have been identified as having at least one issue.

02:05

Review the warnings at the supply system

02:07

by selecting the yellow warning triangles.

02:11

This warning is suggesting that for a system to work correctly,

02:15

it needs to include an element whose

02:17

connector configuration is set to calculate it.

02:21

In this system.

02:22

The fan call unit connector configuration should already be set to calculate it as

02:27

the same fan call unit is used in other systems without an issue.

02:33

A review of the second warning suggests there are disconnects

02:37

even though show disconnects didn't highlight this system as having a problem.

02:42

The warning also states that there is more than one physical network,

02:48

close the warning

02:49

and select a section of duck to review the system name

02:54

FCU 03 supply,

02:58

select the phone

02:59

call unit and do the same.

03:01

And the system name here is GS one.

03:06

The check systems tool has identified a modeling error

03:10

where two different name systems have been connected together

03:14

to resolve the issue.

03:16

The general supply name system needs to be deleted from the phone

03:19

call unit,

03:21

use the tab key to highlight the system,

03:25

select the system

03:26

and then delete it.

03:29

This was the cause of both of the issues which have now been resolved.

03:36

Select the warning triangle on the ventilation system in the bathroom,

03:42

a flow direction mismatches the issue in this case and

03:45

is preventing any kind of flow calculation in the system.

03:50

Close the warning,

03:51

then open the extract grill in the family. Editor

03:58

select the connector

04:00

and note the flow direction in the properties

04:04

for an extract grill. The flow direction at the connector should be set to out

04:10

make the change and load the family into the project.

04:14

Overwriting the existing version

04:20

checking for disconnect and resolving any duct

04:23

or pipe system errors will allow you to

04:26

maximize the information in your project model

04:28

and utilize the full functionality of rev.
