Bulk user management for Autodesk Forma and ACC, in one flow
Adding users to ACC and Forma projects one at a time is slow at enterprise scale. We built HUDA on Autodesk Platform Services to do it in bulk, in one flow.
By Lagarsoft Engineering

If you manage users in Autodesk Construction Cloud or Autodesk Forma, you already know this one. At portfolio scale, adding people to projects one at a time adds up fast. We hit this problem repeatedly across our Autodesk Platform Services development work, so we built a tool to close the gap.
A new hire starts Monday. They need access to 15 projects. You open the first project, add them, set their role, set their company. Then the second project. Then the third. An hour later you are still clicking, doing something that should have taken two minutes.
This ranks as one of the most upvoted feature requests on the official Autodesk community forum, with hundreds of votes from account admins running large portfolios.
Today, Forma user management in the UI still means going into the hub, project by project, by hand, every single time.
Why it feels so broken
What looks like one missing feature is really three separate pains stacked on top of each other.
No bulk user import in the native UI. Need to add 50-plus users to a project in Forma (ACC or BIM360)? There is no native Excel import. The only workaround is a legacy “add members” dialog that takes pasted emails, one project at a time, with no way to set different roles per user. A team onboarding onto a new platform can burn days on this alone.
No cross-project user management. Once a user exists in your account, putting them on multiple projects still means opening each project on its own. There is no “assign this person to these 12 projects” anywhere in the Forma or BIM360 interface. If you run a portfolio of 30, 50, or 100-plus projects, that is a recurring headache every time someone joins, changes roles, or leaves.
The user might not exist in the account yet. This is the one that catches admins off guard. Before you can add someone to any project, they have to exist in your Hub. Onboarding a new consultant? You go to Hub Admin, invite them, wait for the invite to process, then go back and add them to each project. Two separate flows, zero integration between them.
Add it up and a 5-minute task turns into 45 minutes of repetitive clicks across separate workflows.
The APIs are already there
Here is the good news. Autodesk Platform Services (APS) already exposes the APIs that address all three of these at scale. The Forma API (which covers both ACC and BIM360 hubs) has bulk-import endpoints, role updates across projects, and batch user creation. Autodesk built the foundation and the connectors. The rest is just a matter of wrapping them into something usable.
As a certified Autodesk Platform Services partner we develop on these APIs constantly. We’ve built BIM data pipelines, custom dashboards, and Forma integrations for clients across APS.
HUDA came out of that work. We saw the need for a better way to manage users at scale, so we shipped it on the Autodesk App Store.
Introducing HUDA
HUDA is a step-by-step web app built by Lagarsoft and distributed through the Autodesk Design and Make Marketplace. It consolidates three separate jobs into one workflow: user account creation, project assignment and folder permissions.
Every workflow in HUDA is built around an editable table where you add rows one at a time, like filling out a form, but for as many users, projects, or permissions as you need.
Already have the data in a spreadsheet? Import it as a CSV.
Workflow 1: import users to the account
Before any project assignment can happen, users have to exist in your Autodesk account. HUDA’s first step opens an editable table where you add each new user row by row: email, first name, last name. Three new hires? Type three rows. Thirty? Keep going. The table validates as you type and flags duplicates or missing fields on the spot.
When you are ready, HUDA detects which emails do not have an Autodesk identity yet, creates them in bulk through the APS API, and sends invitations automatically. Users show up in your account with pending status right away. You can upload a CSV instead, but for the everyday case of onboarding a handful of people, typing into the table beats opening Excel.
Workflow 2: bulk project member management
This is the core of ACC user management at scale. HUDA gives you an editable table where each row is one operation: add, update, or remove a user on a specific project. Pick the action from a dropdown, type the email, pick the role, select the project. Same person needs to go on ten projects? Duplicate the row and change the project. Someone’s role changing across a portfolio? List them once per project with the new role.
The table has email autocomplete pulling from your account, dropdowns for roles and projects, and inline validation, so you catch typos before you commit anything. It reads more like editing a spreadsheet inside the app than filling out a form.
Before anything runs, a dry-run preview shows you the full diff: what gets added, updated, or removed across every project, so you can check the blast radius before committing. Then an operation queue executes each change with per-row success and error badges, and you can retry failed rows one at a time. When the run finishes, you can download a rollback CSV to undo it if you need to.
CSV import is there too, same schema, loaded from a file. But the row-by-row table is what most admins end up living in.
Workflow 3: folder-level permissions
ACC user management rarely stops at the project level. External architects need view-only access to one folder. Contractors need upload rights to another. Forma handles this, but again, one folder, one user, one project at a time.
HUDA uses the same tabular pattern. Each row grants a permission (viewer, downloader, uploader, editor, or manager) to a specific user on a specific folder, and a visual folder-tree picker lets you point right at the folder. Give a subcontractor uploader access to three folders? Three rows. Grant an external reviewer viewer access across a whole project’s folder set? Add the rows, review, execute. For the granular, ad-hoc permission changes that come up constantly, row-by-row entry is what makes it fast. CSV import is available if you would rather bring the data from a file.
Who it’s for
HUDA is built for account admins and BIM managers at AEC firms who:
- Are standing up Autodesk Forma for the first time and need to onboard a large team
- Run portfolios of 10-plus active projects and regularly move people across them
- Deal with high turnover or frequent role changes (construction firms know this one well)
- Grant granular ACC folder permissions to external consultants or subcontractors
It is also a starting point for firms that want a Forma software development foundation to build their own internal tooling. It is a TypeScript codebase on Next.js App Router, structured to be extended. You can see the full build in our HUDA case study.
Q&A
Does Autodesk Forma support CSV user import natively?
Partially. The native Forma UI has a legacy “add members” option that takes pasted email addresses for a single project, but it does not support structured input with roles, companies, and actions (add, update, remove) across multiple projects. There is no official way to import users from a spreadsheet, or type them row by row, into multiple projects in one operation. That is the gap HUDA fills.
How do I add multiple users to Autodesk Construction Cloud at once?
With the native UI, the closest option is the legacy bulk add in Project Admin: paste a list of emails, assign one role and company to all of them, repeat for each project. With HUDA, you open an editable table and add one row per user with email, role, and target project. When you are done, the tool handles every API call in a single run. CSV import works too, but for the everyday case, typing rows is the fastest path.
Can I add a user to multiple ACC projects at the same time?
Not through the native ACC interface, which makes you open each project individually. HUDA does it directly: list the user once per project as separate rows, and the tool processes the assignments together. A dry-run preview lets you review the full scope before anything runs.
What is Custom Integration activation in ACC, and do I need it?
Custom Integration is a setting in the Forma account admin panel that authorizes third-party apps, built on APS, to make Admin API calls on behalf of your account. It is a one-time activation done by an account admin, and it is required for any Forma integration that uses the /hq/v1 admin endpoints. Without it, the API returns a 401. HUDA’s setup guide walks you through enabling it, but it is worth knowing upfront, since it is a prerequisite before any admin operation can run.
Does this work for BIM 360 accounts, or only Autodesk Forma / ACC?
It works with any hub reachable through the APS Data Management API, which covers both ACC and BIM 360 accounts. The hub selector filters to show only relevant Forma / BIM 360 hubs, so you will not accidentally connect to the wrong environment.
Is HUDA an Autodesk product or a Lagarsoft product?
HUDA is a Lagarsoft product, distributed through the official Autodesk App Store. Lagarsoft is a certified Autodesk Platform Services partner, so the app has been reviewed against Autodesk’s integration standards. It uses only official APS SDKs and APIs. No reverse-engineered endpoints, no unsupported workarounds.
Can I use this as a base for building our own internal admin tooling?
Yes. If your firm needs a customized version, wired into your HR system, your ERP, or your own project naming conventions, that is a Forma software development engagement we can take on. The codebase is TypeScript throughout and built on Next.js App Router, so it is straightforward to extend. Reach out and we will talk through what a custom build looks like for your team.
Try it
HUDA is available on the Autodesk App Store. If you are on Autodesk Forma or ACC and managing more than a handful of projects, it turns the per-project clicking into a single bulk run.
