Your Letterhead, Every Time

Every calc sheet the Structural Agent produces carries a full project header, and you control every field in it: project name, project number, project task, calc by, calc date, checked by, checked date, and the project address, plus your company logo pulled from your Standards folder. Set the fields and the logo once, and every Mathcad sheet, Excel workbook, and PDF report comes out on your firm’s letterhead. Here is the header on a finished calc sheet:

Calc by and checked by are your QA trail. Fill them the way your firm’s review process expects: you are the engineer of record, and the header carries that on every page.

One-Time Setup

1

Put your logo and templates in the Standards folder

Open Files from the account menu and find the Standards folder, marked with the book icon. Upload your logo (a PNG with a transparent background works best) along with anything else that defines your format: a report template, a sample calc package, formatting notes.

No Standards folder yet? Right-click any folder you can edit in Files and choose Set as Standards Folder. Organization-wide setups are covered in Your Standards Folder.
2

Confirm Formatting standards is on

Click the + button in the message box. Formatting standards shows a toggle, on by default. With it on, the agent reads your Standards folder before it formats anything: no tagging needed in each prompt.

3

Save your header defaults as a standard

Tell the agent the fields once and keep them:
Example: header defaults
Use these header fields on all calc sheets for this project:
Project: Office Building Demo
Project number: 24-1042
Calc by: J. Doe, PE
Checked by: R. Roe, PE
Address: 1600 4th Ave, Seattle, WA 98101
Logo: logo.png from the Standards folder.
Save this as a standard.
The header block lands in your Standards folder, and future conversations pick it up automatically. The task and the dates change with every calc, so leave those to each request.

​
Generate the Deliverable

Ask for the calc or report the way you normally would: the header and formatting come from your standards. Set the task per calc, and override any field inline when a sheet needs something different:
Example: calc package
Create the retaining wall design calcs for the north wall: 10 ft
retained height, level backfill, 120 pcf soil, no surcharge,
ACI 318-19, US units. Project task: North Retaining Wall.
Example: field report
Write up the findings from @Site_Walk_Photos.pdf as a field
observation report on our template, with the standard header.
The finished document lands in the chat as a download link and in your Files area automatically. The same setup carries to RFIs and RFAs: the agent follows the forms it finds in your Standards folder.

​
One-Off Formats

For a client format you will use once, skip the Standards folder: attach the template with the + button and reference it in the prompt.
Example
@Client_Report_Template.docx Use this template for this report
instead of our standard format.
Attachments and tagging are covered in Using the Chat Input and Mentions & Attachments.
