A valuable tool that has many uses outside of arch-viz work, Sweep extrudes individual or groups of profiles (polygon islands and open-beziers) along a path of selected points, creating UVs (segmented or peeled) and part-names for easy selection and texturing.

Useful for a wide variety of tasks,

  • Window and door trim or moulding;
  • Fascia, rafters, soffits, drip edges and some types of guttering;
  • Baseboards (skirting boards) and other mouldings around the inside of a room;
  • Door liners and door stops;
  • Window and picture frames;
  • Shiplap cladding;
  • Curved walls;
  • Architectural window shades;
  • Plus much, much more...

Poly-To-Window tool for modo

Vector Scale

A super handy tool that enables you to interactively scale geometry, in one or mesh item layers, based on a single known length or by a multiplication factor or by bounds. In addition, choose to centre the geometry around the world origin and/or rest it on the ZX ground plane.

You can use it for,

  • Scaling geometry (e.g. polylines from imported architectural drawings) to a precise size based on a single known length;
  • Scaling any geometry in one or more mesh layers to a given size, along one or more dimensions;
  • Resting one or more mesh layers on the ground plane, either individually or grouped;
  • Centering one or more mesh layers around the world origin, either individually or grouped.

Align Mesh A-to-B

Moves all the geometry within a mesh item (at the component level; no item transforms) from a source point to a target point or the world origin. Allows per-axis alignment using novel tool handles and supports modo's 'select through' workflow.

You can use it for,

  • Precise alignment of polyline drawings (e.g. plans, elevations) to one another;
  • Anytime you wish to align one mesh to another along one or more of the major axes.
Align Mesh tool for modo

Select by Height

Selects all geometry that matches the height of a pre-selected vertex, edge or polygon. In addition, this command enables the selection of geometry within a range of heights, as well as, selecting all geometry above or below the height of a selected vertex, edge or polygon.

You can use it for,

  • Easy selection of geometry based on height or level above the ground; e.g. selection prior to using move or extrude on walls, floors and window openings;
  • Checking elements of your model to ensure they are positioned at the same height; e.g. walls, floors and window reveals.
Select by Height command for modo

Select by Normal

Selects all polygons whose normal matches that of a previously selected polygon, and permits refinement of the selection based on a variety of filters; e.g. you can limit selection to polygons in the same plane as the target polygon.

You can use it for,

  • Easy selection of walls or other polygon surfaces based on matching normals;
  • Creating a polygon selection prior to applying materials, projecting UVs and more.
Select by Normal command for modo

Align Points A-to-B

Align a selection of points to the last selected point, along one or more axes, with a given amount of offset. This tool supports multiple mesh item/layer selections and is designed for use with modo's fast 'Select Through' workflow; Hence, you can change your point selection on the fly and align different pieces of geometry whilst this tool remains active.

You can use it for,

  • Moving the end of a wall to a target position;
  • Moving the end of a piece of steelwork or trim to a target position.

Arch Profiles

Generates 2D arch and half-arch shapes (polylines or polygons) that can be extruded or swept (path or radial) to create 3D geometry, or used as a cookie cutter.

You can use it for,

  • Arch shape path for sweeping geometry to create 3D arches; e.g. using Arch-E’s Poly Sweep tool.
  • Template to drive boolean tools for cutting arch shapes into existing geometry (cookie cutter).
  • Starting point for creating moulding profiles (e,g. cyma recta).
  • As a polyline profile for use with modo’s built-in Radial Sweep tool to create 3D arch-derived shapes.

Part Names To Masks

Generates material masks (group and material) for each of the polygon part-names within your scene, whilst avoiding duplication of pre-existing part-type masks.

You can use it for,

  • Automagically creating part-type material masks in a single click.
  • Create materials for all the parts produced by the Door Template tool, for example, in a single click.
Part Names To Masks command for modo

Door Templates

Horizontal Slider Window and Door tool for modo

Add Material Groups

Generates material masks specifcailly for each of the polygon part names created by the window maker plugins. This spares you from having to creating the masks and materials by hand. Furthermore, once these have been created, modo will apply use these materials whilst the window generator tools are active.

You can use it for,

  • Automatically generating material groups/masks for each part (polygon part name) of the window.
  • Enables modo to show materials whilst MultiWindow, Box Sash and Horizontal Sliders tools are active.
Add Material Groups command for modo

Add Locator To Corner

This command will add, orientate and position a new locator at the point where the two selected edges meet. It is highly specialised towards this single task and will only correctly orientate the locator when the correct edges are chosen.

You can use it for,

  • Creating locators at the corner of a window or door reveal.
  • Aligning windows to window openings.

Window Furniture Models

A set of window furniture mesh presets for use with modo; These are sub-d (designed for sub-division smoothing) models.

You can use them for,

  • Adding extra layer of detail and realism to windows.
  • Use as base to create your own handle or vent variations.
Window Furniture Mesh Presets for modo

Windows Made Easy

Create compelling casement, fixed-light, double-hung and slider window geometry for use with your 3D buildings (arch-viz, digital set extensions, games) using this professional and fun to use plugin for modo. Then, add an extra degree of realism using the included 3D window furniture models (handles, pulls and vents).

The Window Maker Kit is designed to be easy to use and the underlying procedural nature of the tools makes them highly adjustable, which gives you with an enormous amount of creative control over the layout and appearance of the windows.

However, with great power there must also come -- great usability. Wait. What? Yes, these tools have been designed with you, the artist, in mind; for example,

  • Detail where it matters - apply extra detail (e.g. chamfers) just where you need it.
  • Easy selection and texturing - polygon part names and UVs are automatically generated. And UV scaling is consistent across all three tools.
  • Fast Alignment - use the 'Add Locator To Corner' command to aid easy fitting of the windows.
  • Reduce visual clutter - the user interface for each tool is divided into logical sections, which can be individually collapsed.


  • This plugin requires a copy of modo 10, modo 11, modo 12 or modo 13 series to be installed1.
  • Supported operating systems (64-bit only): Windows 10 or macOS 10.10-10.14 or Linux (limited distros)2
  • An internet connection is required to access the User Manual.

1Please note that we cannot guarantee support for beta versions of modo and updates to modo may require plugin updates.

2Linux version requires an up-to-date distro (not LTS) and is compiled on Arch Linux, which is my primary development environment. LTS distros version is coming soon. Please contact me for more info.


  • The tools are primary designed for use with modo’s (default) Y-up world axis, however, many support all up-axis orientations; Those that don't will create geometry aligned along the X and Y axes.
  • Generated UVs are stacked and proportional, but they are neither packed nor normalized to fit in the 0-to-1 space. Hence, pack and paint (if required) is left to the artist.
  • Materials are not created, but polygon part names are generated (same across all tools) to enable easy selection and material/group assignment. And the kit contains two plugins for creating materials from part names in your scene.
