Drawing in 3D from engineering designs in 2D, 3D, and BIM – 2

3D Drawing from Engineering Plans

In today’s dynamic world, the art of 3D drawing has taken on various captivating forms, each with its own distinct allure and widespread recognition. From the elegant sophistication of black and white 3D drawing to the playful charm of cartoon 3D drawing, these diverse styles have carved out a prominent place in the realm of digital creativity. In this article, our focus shifts to crafting a window in a 3D drawing using a basic 2D engineering drawing of low quality as our starting point. While there are more straightforward techniques available for generating windows in BricsCAD BIM, we’ll explore those in future segments of this series.

Making the frame

To do this:

  1. Begin by accessing the BOX tool, located in the Solids section of the Model tab on the Ribbon. Keep the insertion point at 0, 0, 0 for organizational purposes.
  2. Next, utilize the DYN boxes to input the width and length dimensions as indicated on the provided drawing.
  3. Subsequently, set the height (z-axis) using the same method.
  4. Following that, employ the OFFSET command to offset the edges of the box and draw the dimensions, similar to the standard 2D process, but on the surface of the box rather than the 0 plane of the z-axis.
  5. Switch the View Style to Shaded using either the Properties Panel or the View tab in the Ribbon.
  6. To create the recess for the window, hover over the polygon until the boundary turns green, then select Extrude from the Quad and drag through.
  7. Repeat the previous step to slightly extrude the frame of the window’s “door.”

The handle

To craft the handle, I began by utilizing basic shapes such as the box and cylinder primitives, then extended the spline through extrusion.

To do this:

  1. Create a rectangular box using the drawing tools.
  2. Place a cylinder at the midpoint of the top surface of the rectangular box.
  3. Input the dimensions accurately based on the provided 2D plans.
  4. Craft the handle’s shape using a Spline tool.
  5. Extrude the shape to finalize the handle design.


To do this:

  1. Begin by accessing the DMFILLET command, located in the Direct Modeling section of the Modeling tab on the Ribbon.
  2. Choose the edges you want to fillet, then input the desired radius value.

Details and tweaking

I created the window panes by utilizing the Extrude tool and selecting the create mode, which prevented the solids from automatically fusing together. To distinguish the glass from the frame, I accessed the color drop-down menu in the Properties panel and changed the color from ByLayer to blue.

Lastly, I utilized 3DROTATE to rotate the window along the x-axis by 90 degrees. 3D Rotate functions similarly to 2D rotate, with the distinction that you can rotate around a specific axis.


At this point, I was satisfied with my model but wanted to be able to adjust its size without having to remodel it. To achieve this, I utilized Parametrize.

To do this:

  1. Access the PARAMETRIZE command.
  2. Choose the object(s) you want to parametrize.
  3. Open the Mechanical Browser to view all your constraints.
  4. Modify the constraints as needed in the Properties panel.
  5. An object will appear in red in the Mechanical Browser if it is over constrained.
  6. Fix constraints will restrict the ability to rotate an object.

In conclusion, this article has demonstrated the process of creating a window frame in a 3D drawing, starting from a basic 2D engineering plan. Despite the availability of more straightforward methods in BricsCAD BIM for generating windows, the detailed steps outlined here provide valuable insights into the intricacies of 3D modeling. By following the techniques outlined, one can create a visually appealing window frame complete with fillets, handles, and glass panes. Furthermore, the versatility of parametrization allows for easy adjustments to the size and dimensions of the window frame without the need for extensive remodeling. Whether it’s a black and white technical drawing, a whimsical cartoon illustration, or any other type of 3D drawing, the principles and techniques covered in this article can be applied to create stunning results in various contexts, catering to any 3D drawing, be it a black and white technical sketch, a playful cartoon rendition, or simply some 3D drawings.
