IMPLICIT: lightweight lattices for 3D-printed parts from Alibre
A bracket has been fully designed in Alibre Design and is to be 3D printed. The outer shape is fixed: holes, contact faces and dimensions match the surrounding parts. The inside, …

Alibre Design API: developing tools, with or without AI
Many design departments have tasks that always follow the same pattern: creating parts from table values, transferring data from the model into an in-house application, showing …
DXF Layer Fix: move DXF geometry to the layer your software expects
A drawing is exported from Alibre Design or another CAD program as a DXF file and opened in CAM, laser or nesting software. Instead of the contour, you get an empty drawing or a …
STEP Web Viewer: share Alibre assemblies as a 3D viewer
A model builder has designed the hull of a ship in Alibre Design: 4,571 parts, frames, stern tubes, rudder gear, drive train. The client has no CAD software but still wants to …
Converting STL to STEP: meshes as solids in Alibre Design
A customer sends a bracket as an STL file, downloaded from a 3D printing portal. A part of your own has to be fitted to it: take over the hole pattern, reuse the contact faces, …
Converting STEP and OBJ to GLB: 3D models for web pages
Showing a CAD assembly in the browser, rotatable, with every colour and part name intact: the converter turns STEP or OBJ into a single file that any browser displays without …
Box generator for the laser cutter, part 1: the 2D cutting layout
Designing a finger-jointed box is no big deal. Once. The second time, with different dimensions, you start all over again: redistributing the fingers so that they end the same way …
Pipe dimensions table: DN, PN and wall thickness to DIN and EN
Anyone modelling a pipe in CAD or building a bill of materials works with three number systems: the nominal size DN, the nominal pressure PN and the actual dimensions outside …
ISO 286 fits explained: how to read tolerances such as H7/g6
The drawing says Ø 25 H7/g6. So the hole is made to H7 and the shaft to g6. What follows from that is not stated: how much clearance remains, whether the parts can be assembled by …
Material editor for Alibre Design: creating and maintaining materials
Alibre Design comes with an extensive material library. It is sufficient for mass and centre of gravity, but not for many calculations: in the supplied library, only the density …
U-channels UPN and UPE: dimension table to EN 10365
The U-channel generator creates U-channels (channel sections) in Alibre Design as 3D parts that comply with the standard. Only the type, section and length are selected.
Metric screws (ISO): head types, standards, property classes
Anyone designing in CAD needs screws all the time, and usually not as a single item but in series across several sizes, lengths and property classes. This article covers the five …
Steel angle table: L-sections with dimensions, weights and standards
Frames, bracing, brackets, supports: steel angles, also called L-sections or angle irons in the trade, are found wherever a lot of stiffness is needed from a small cross-section. …
