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.
| 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 |
|---|---|---|
| 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) |
