Making sure that there are no open documents before a new document is opened or that there is always just one open document when executing a job.


For powerJobs 19 or newer:

Open coolOrange.Applications.psm1 located in "C:\ProgramData\coolOrange\powerJobs\Modules"

For powerJobs 18 or earlier:

Open Setup_Job.ps1 located in "C:\ProgramData\coolOrange\powerJobs"

Add following line of code under the Register-Application cmdlet if you are using Inventor:


If you are using InventorServer add this line of code under the Register-Application cmdlet:


This sets the Close-Document counter to 1, that means every time a Close-Document is executed, the application restarts and therefore you should always have just one open document. Note that Close-Document has to be executed for this to work. To ensure that it will always be executed there are 3 possibilities:

  1. Add Close-Document to the Setup_Job.ps1 which gets executed before every job
  2. Add Close-Document at the beginning of your job
  3. If the job crashes, Close-Document will not be executed. In that case you can catch the exception with a try catch and add Close-Document in the catch block:
try {
     <your code>
} catch {


This can affect the speed of the jobs being executed as the application is restarted after every Close-Document
