3. Custom Checks

You can upload your own rulesets for running custom checks of your models. Once the ruleset have been uploaded on bimspot they will be available to the entire project team.

The basis for this are rulesets created and saved in Solibri.

Admin rights are required for the administration of these rulesets. The custom checks is then possible for every user.

Uploading and managing ruleset (only Admin)

Ruleset must be uploaded on bimspot via a .cset file by using the Ruleset manager.

To upload a ruleset:

  1. If no ruleset has been uploaded yet, click on Upload Custom Ruleset;
Upload of first ruleset on bimspot

2. To upload new rulesets or to manage existing ones, click on the three dots and choose Manage Ruleset.


How to run Custom Checks

Once the Admin has uploaded the ruleset(s), all users invited to the project can use those to easily run a Custom Check in 4 steps:

  1. Choose Custom Check from the Model Check homepage;
  2. Select the wished ruleset;
  3. Select building part(s);
  4. Click on Submit.

Note: For both dropdown menus multiple building parts for each discipline can be selected.
