Some features of BoA

Integrated Work in 2D - 3D

Depending on its complexity, a project BoA can be built on one or more files. Each BoA file contains either 2D or 3D objects or a mix of 2D and 3D objects.

Library of 3D and 2D objects

BoA can work with libraries of 3D or 2D objects: architectural elements, frames, opening shapes, furniture, symbols, etc..

BoA includes a library of predefined objects. This library can be modified or supplemented by customized library item. Any BoA project may use the standard library or one or several personalized libraries. Sharing a library between several users is very easy.

Working in 3D with the WorkPlan

The WorkPlan is a tool that enables and facilitates the work in 3D. Thanks to the WorkPlan it becomes easy to work directly in cut, in section, in axonometric or conic perspective and of course in plan.

Layout management

A layout sheet file associated with the 3D model of a project can prepare and automate printing tasks: preliminary design, building permits, monitoring, etc.. Once the layout sheet is complete, any modification of the 3D model is automatically transmitted in the layout sheet without extra operation.

3D volumetric objects

BoA uses 2D objects and 3D objects. 3D objects are volumetric. The basic object of BoA, called "block", is used to create walls, slabs, roof panels, stair steps, poles, etc.
A block can be pierced by one or more openings (door in a wall, hopper in a roof panel, etc.).
3D objects can be grouped into reusable library items. All 3D objects are volumetric, that is apparent in section view.

Geometric dependency

The geometrical characteristics of an object, size or location, are defined either directly or by reference. When they are defined by reference, they are in relation with other existing objects. For example, two doors can be positioned in front of each other on two walls. After moving or deforming the walls, the two doors will remain in front of each other.

Associative cotation

A set of dimension tools are available in BoA: single or multiple dimension, linear or angular dimension, etc. When creating a dimension you can either enable or disable associative dimensioning. When associative dimensioning is enabled, the dimension is linked to the objects which it is a measure of. The dimension is recalculated if the referenced objects are deformed, moved, or deleted.


BoA allows the solar study of a building. Relative to the building, the position of the sun is known as a function of the day, the time and the geographical position of the building. With the position of the Sun, perspective with shading can be displayed.

Landscape integration

Every building permit must include an impact assessment project in the countryside where he is destined to be realized. BoA can display a landscape integration composed from the 3D model of a building and a photo of the site where it will be built. This is a huge time saving for an operation which, even today, is often done manually by cutting / gluing / photocopying of a printed photo of the landscape and printed perspective of the building.

Mini quantifier

BoA is not a quantifier or billing software. However it contains the measurement tools to generate a text or spreadsheet file containing all the measures and dimensions related to a project. Once it has been generated, this file can be edited to get a pricing or any other quantified document.

Terrain modeling

A set of tools are available to do terrain modeling. With these tools, a building can be shown as a perspective in its environment. The terrain can be sliced to visualize the level curves, etc..

Work in plan, in perspective, in axonometric, in cut, in section, etc.

A BoA project can be displayed in different kinds of views: top view, or any other plan view, cut, section, axonometric, conical perspective. Cut views and section views can also be customized. This is visualization, but not limited to: the modeling work is done in all views without restriction.
