Clash Detection Dialog

Allows you to identify sets of elements to be used for the detection of physical clashes and clearance problems between the elements. Also used to review, track, manage, group and save clashes. All jobs that you create are stored in the active file along with the results of the clash detection operation. You can also store the job in a DGNLib.

You can access this dialog from the following:

Ribbon: Modeling > Analyze > Clash Detection > Clash Detection

Setting Description

Create a New Job

Adds a new entry to the job list with the default name, Untitled Job. Untitled Job is highlighted and ready to be renamed.

CLASHDETECTION JOB NEW

Save the Selected Job to Disk

Saves the job setup for future use. The job is saved in the active local file.

CLASHDETECTION JOB SAVE <job name>

Duplicate the Selected Job

Copies the selected job. When you click the icon, a new entry is added, ready for a name change.

CLASHDETECTION JOB COPY <job name>

Update the Selected Job from the Library

Synchronizes the local job to match the one in the DGN library.

CLASHDETECTION JOB UPDATE <job name>

Create a New Group

Creates a new group to which you can add clashes. When you click the icon, a new entry is added, ready for a name change.

Delete

Deletes your selection from the All Jobs list box. Deletes the selected job, the results, or a selected group. If a group with results is selected for deletion, all the clash results in that group, move to the parent directory. This icon is not available if the selected job is a library job.

CLASHDETECTION JOB DELETE <job name>

All Jobs List Box

Lists the jobs created for clash detection. Once you run a clash detection job, a Results directory displays in the list box under the job name. Pause the pointer over the Results entry to see if the clash detection is successful, the number of clashes detected, and when the clash detection was last run. If any clash groups are created, they also display under the results of that job.

Jobs can be local or from a library or a job whose local and library copies match. You can save and then modify local copies of the jobs. Once a job is copied locally, it is not automatically synchronized with the library job. It can, however, be manually synchronized.

	The grey book icon indicates that the job has not been copied locally.
	A filled blue book icon identifies a local job.
	A green check mark appears next to the job when it has been copied locally, and still matches the library job.
	The blue delta icon appears next to a job if it has been copied locally, but no longer matches the library copy.

Right-clicking the Jobs list box opens a menu with options identical to the items on the Job menu.
