STACEY MORYKIN: Hello and welcome to Gravity Pipe Network

00:02

Interference Check.

00:04

My name is Stacey Morykin, Design Technology Manager.

00:07

Interference checking lets you quickly identify

00:10

pipe network parts that may conflict with each other.

00:13

This feature compares the actual

00:17

to identify parts that physically overlap, collide,

00:21

or intersect in an inappropriate way or that

00:24

have violated the predefined proximity based criteria.

00:29

In this session, we will walk through the specific steps

00:31

to run an interference check.

00:33

We will select the pipe networks and set the interference

00:36

reporting criteria.

00:39

We are now at the first step of the workflow,

00:41

running an interference check.

00:43

So let's switch over to Civil 3D and get started.

00:48

We begin by opening the interference checks

00:50

in Civil 3D_Begin DWG file.

00:54

In this Civil 3D drawing, we have a sanitary sewer network

00:58

and a storm network that goes to an underground basin.

01:02

The design portion was just established

01:04

based on the rules we have set for both networks.

01:07

There are also two profiles for this area

01:09

so we can take a closer look at the crossing pipes.

01:13

To determine whether clashes are present between these two

01:16

networks, we will run an interference check.

01:18

This tool can be found in one of two ways,

01:21

under the Analyze tab at the top under the design

01:25

panel, Interference Check, or under the pipe

01:29

networks in the Prospector tab of the Tool Space.

01:34

Left pick on the Interference Check from the ribbon.

01:37

When the command is active, it asks

01:39

to select a part from the first network.

01:43

This can either be a pipe or a structure.

01:46

You will click on a part in the plan view

01:48

from the sanitary line, which is represented

01:50

by a green color in the drawing.

01:53

The next prompt asks for another part,

01:55

either from the same network or different networks.

01:58

Choose the storm sewer line, represented by the cyan

02:00

color in the drawing.

02:05

When the Create Interference Check dialog box appears,

02:07

we will give our check a name.

02:10

We will enter Sanitary & Basin 2.

02:15

We'll also ensure that the networks are represented

02:17

in the boxes appropriately.

02:19

We have our Sanitary Sewer network

02:21

and we have our Basin 2 network.

02:24

We can also set the layer of this interference check.

02:28

We can also set the style, which we'll choose basic for now.

02:32

This will actually show an icon at the interference locations.

02:37

Click on the 3D proximity check criteria

02:39

at the bottom of the dialog box.

02:42

The 3D proximity check will check

02:44

in the x, y, and z directions for a distance

02:48

along those pipes.

02:49

We can also use a scale factor.

02:51

For now, I will set this to 10 feet.

02:54

Click OK, and click OK again.

03:00

When the command finishes running,

03:02

Civil 3D tells us that, in three areas,

03:05

there is a clash between the two pipe networks.

03:07

Click OK.

03:09

We can continue creating interference checks

03:11

for other networks in our drawing,

03:13

but let's take a closer look at the one we just created.

03:17

In the Tool Space Prospector tab under Pipe Networks,

03:22

click to expand interference tracks.

03:25

Left click on the Sanitary & Basin 2 interference check.

03:30

View the three locations in the item view area.

03:34

If you do not see the item view area,

03:35

try placing your mouse at the bottom of the prospector

03:38

and dragging upwards.

03:43

If you made a mistake with entering in the distance,

03:46

right click on the name of the interference check

03:49

and select Interference Check Properties.

03:54

Through this dialog box, you can change the style

03:56

under the Information tab.

03:59

And you can also view the statistics, as well as

04:01

the criteria.

04:03

If you made a mistake when you set your distance,

04:05

you can go back into the Criteria tab,

04:07

change from 10 feet to five feet, and click OK.

04:14

Civil 3D will rerun the interference check

04:17

and tell us that there are now two interferences

04:20

found on the pipe networks.

04:23

By zooming into the plain view, you notice two orange color

04:27

circles.

04:28

These glyphs denote the location where the two pipe networks are

04:31

within the five foot criteria.

04:34

You can also right click on any interference in the item view

04:37

area and select zoom 2.

04:44

In the next session, we will navigate and correct

04:46

the interferences.

Run an interference check - Exercise

Interference checking lets you quickly identify pipe network parts that may conflict with each other. This features inside Civil 3D compares the actual 3D Model of the pipe network to identify parts that physically overlap, collide, or intersect in an inappropriate way, or that have violated the predefined, proximity-based criteria.

Objective 1: Run an interference check

  1. Open Civil 3D.
  2. Open Interference Checks in Civil 3D_Begin.dwg.
  3. Navigate to the Analyze Tab > Design Panel > Interference Check.



  4. Click Interference Check.
  5. Click on any part in the Sanitary Pipe Network (Green).
  6. Click on any part in the Basin 2 Pipe Network (Cyan).
  7. In the Create Interference Check dialog box, Enter Sanitary & Basin 2 for Name.
  8. Packages > select Search for a Package.
  9. Network 1: - Sanitary Sewer Network
  10. Network 2: - BASIN 2
  11. Layer = C-STRM
  12. Interference Style = Basic



  13. Click 3D proximity check criteria at the bottom of the dialogue box.
  14. Check Apply 3D Proximity Check.
  15. Select Use distance.
  16. Enter 10.
  17. Click OK.



    Civil 3D will provide a notification of the Number of Interferences found. In this case, three total interferences were found.
  18. Click OK.



    Notice the three orange circles denoted in the drawing file, and the new interference check in the Prospector Tab > Pipe Networks > Interference Checks.



  19. Right Click on the Sanity & Basin 2 interference check in the Prospector.
  20. Click Interference Properties.



  21. Criteria Tab at the top, Enter 5’ for Use Distance.



  22. Click OK. The total number of interferences is now 2.
