Inside the Flizen toolkit

More behind every detail.

Flizen is a CAD add-on with advanced 2D tools for engineers and drafters in aluminium joinery and facade design. Explore how geometry, parts and information come together in your drawing.

Parametric 2D details

Draw the elements used every day in aluminium and facade details. Set their parameters, inspect the preview and return to their settings when the design changes.

Sheet metal and membranes: thickness, placement, bends and representation.
Soft and hard insulation along paths or within selected boundaries.
Welds and seals, including sealant and backing rods.
Round holes and slots, with countersinks, counterbores and axis markings.

Sheet metal parameters. Thickness, bend radius, placement, material and hatching, with a geometry preview. — Sheet metal parameters

Parts, libraries and databases

Standard Parts supports selection and insertion into drawings. Data Center organises part definitions, reusable building blocks and revisions in part databases.

Browse categories, search parts and preview the selected variant.
Choose the dimensions exposed by a part definition and insert its 2D representation.
Prepare your own databases of parts and reusable components in the authoring workflow.

Object data and materials

Flizen objects hold structured properties that other tools can use. Material settings bring names, layers, hatching and technical properties into the same workflow.

Object properties provide source values for semantic annotation fields.
Organise materials by code, name and group.
Define material profiles for drawing appearance and supported physical or bend properties.

Material library. Material groups, codes and names, with profiles for layers, hatching and technical properties. — Material library

Intelligent annotations

Use material, thickness, length and other supported properties directly in a label. Linked fields can follow changes to their source object while the layout and manual additions remain under your control.

Combine semantic fields with your own text and units.
Manage text, leaders, scales, appearance and annotation configurations.
Prepare labels in different languages, independently of the website language.

A label built from object data. Designation, material, thickness, length and units composed into a sheet-metal annotation. — A label built from object data

Drawing and documentation tools

Move from detail geometry to an organised sheet with tools for construction, editing and presentation. Profile projection also supports creating a representation along a chosen path.

Auxiliary lines: directions, offsets, bisectors and perpendiculars.
Tools for joining, splitting, cutting and selective covering of supported geometry.
Create layout viewports with scale, spacing, source markings and model synchronisation.

Create viewports. Choose the layout, scale and spacing, with options for source markings, model synchronisation and separators. — Create viewports

Part construction, 3D and assemblies

Build FSP develops reusable building blocks, parameter relationships and 3D construction to support consistent part views for 2D documentation. Work on 3D and assemblies is ongoing; the final scope may change.

The developing 3D workshop

Early development build

A real shaded part model, its analytical profile and construction history. The workshop’s scope is evolving.

Built from everyday engineering

A substantial toolkit. A practical purpose.

Flizen grows out of hands-on work with facade documentation and the small, repetitive tasks that fill a designer’s day.

Around 160,000 lines of code already underpin the project: native C++ CAD modules, a WPF interface on .NET 8, and Open CASCADE geometry for the developing 3D workshop.
