Specifications for a flawless order

At Bax Metaal, we believe quality starts at the drawing board. We like to make complex sheet metal and tube constructions as easy as possible for you, and that starts with correctly submitted files. On this page you’ll find all the specifications your drawings need to meet, so we can process your order quickly, accurately and without surprises.

File specifications

Below you’ll find the general specifications we like to use for correctly submitting files. If you have any questions or are missing information for your project, please don’t hesitate to contact us.

General guidelines

Guideline
Always submit files at a 1:1 scale, in millimetres
The PDF work drawing and the STEP file of a product must always match 1:1; we are not responsible for any discrepancies between them
For both quote requests and orders, always include an assembly STEP file for use in our (costing) software
Give a file a new revision number with every change (e.g. <drawing number>-<revision>); without incrementing the revision, there is a risk that the old, unchanged part gets produced

 

DXF, STEP and PDF files (guidelines)

Want to know more about correctly submitting a STEP file? Check out our detailed guidelines for STEP files.

DXF files can only be used for flat, single-piece parts; STEP files are always preferred.

Below are the drawing guidelines per file type. A PDF work drawing supports review and post-processing and ideally includes:
File type Application Guideline
DXF Sheet metal One part per file
Draw at actual size (1:1 scale, in millimetres)
Contours at nominal size
Draw cutting contours in white
Engraving lines in cyan
Keep engraving contours at least 0.1mm from cutting contours so the top surface remains intact as one piece
For pre-drilled holes, use the correct diameter for tapping
No dimensioning, centre lines or sketch lines in the file

 

File type Application Guideline
STEP Assemblies 1:1 scale, in millimetres
Separate parts (not merged into a single solid)
Names of internal parts must match the PDF drawing(s); preferably including the revision in the assembly STEP file as well
Item numbers on the drawing and/or parts in the BOM must match the parts in the STEP file

 

File type Application Guideline
STEP Sheet metal One part per file, 1:1 scale in millimetres
Holes and contours always drawn perpendicular to the material
Engraving lines 0.1mm deep and at least 0.3mm wide
Keep engraving contours at least 0.1mm from cutting contours so the top surface remains intact as one piece
See the tables for the correct bend (inner) radius for formed sheet metal

 

File type Application Guideline
STEP Tube laser work One part per file, 1:1 scale in millimetres, nominal dimensions
Contours perpendicular to the wall thickness of the tube/pipe
Engraving lines 0.1mm deep and at least 0.3mm wide
See the list with radius per material and wall thickness. The inner radius = always outer radius minus wall thickness.
Do not indicate weld seams in the file

 

File type Application Guideline
PDF Work drawing (sheet metal and tube laser work) Drawing number and revision
Part name
Material type and thickness
Projection method (American or European)
General tolerances (with ISO reference)
