Create Drawing Border And Title Block

Create Drawing Border And Title Block

File: Drawing_Document_Scripts/Create_Drawing_Border_And_Title_Block.py
Version: 1.1
Document Type: None required (creates a new CATDrawing)

---

Description

Creates a new CATDrawing document and populates its background view with a standard ISO 5457 border and an ISO 7200-inspired title block. A dialog lets the user choose the paper size before the drawing is created.

The border follows ISO 5457 margins (left = 20 mm, top / right / bottom = 10 mm) for all paper sizes. The title block is 180 mm × 55 mm and is placed at the lower-right corner of the border. Each data field is created as a named, empty text item so that the Update Title Block From Properties script can fill in values from linked model properties automatically.

Title Block Layout

The title block is 180 mm wide × 55 mm tall and is placed at the lower-right corner of the border. It contains five rows (bottom to top):

Row	Height	Columns	Named fields
Drawn By / Date / Approved	10 mm	60 / 60 / 60 mm	Drawn_By, Date, Approved
Scale / Sheet / Revision	10 mm	60 / 60 / 60 mm	Scale, Sheet, Revision
Part Number / Material	10 mm	120 / 60 mm	Part_Number, Material
Title	15 mm	Full width	Title
Company Name	10 mm	Full width (centred)	Company

Each row contains a small field-name label (2 mm font) and an empty named value text (3.5 mm or 5 mm font). The named value texts can be populated later using Update Title Block From Properties.

Notes

• The new drawing is left unsaved — save it manually after reviewing the result
• Font sizes and margins follow ISO conventions but can be adjusted directly in the script constants at the top of the file
• The projection symbol (first/third angle) is not drawn automatically — add it manually to the background view after creation
• If the script is run on a sheet that already has content, it creates a new document rather than modifying the existing one
