Note: This release is in preview. Features described here don’t become generally available until the latest general availability date that Salesforce announces for this release. Before then, and where features are noted as beta, pilot, or developer preview, we can’t guarantee general availability within any particular time frame or at all. Make your purchase decisions only on the basis of generally available products and features.

Org Shape Permissions

A Salesforce admin for the Dev Hub org must assign permissions to users who plan to create org shapes, or create scratch orgs based on an org shape. If you already have a permission set for Salesforce DX users, you can update it to include access.
Access Permissions
Create an org shape Object Settings > Shape Representation > Create, Edit
Delete an org shape Object Settings > Shape Representation > Delete
Use an org shape to create a scratch org No additional permissions are required besides the ones for creating scratch orgs.

You don’t require the “Modify All Records” permission to delete shapes created by others because there can be only one active shape in the org at a time.

Supported Licenses

In addition to providing users with appropriate permissions, be sure to assign the Salesforce license to Org Shape users. Other user licenses aren’t supported at this time.
