The software, previously referred to as "Toolbox", was rebranded to the name "Microvellum" in the year of 2025. If your software version was released prior to the year 2025, you may see certain settings with different names reflecting this change, such as 'Toolbox Setup' becoming 'Microvellum Setup'.
When transitioning from Microvellum OEM or AC to Microvellum BSB, it may be desirable to reconfigure the graphics to resemble your prior workspace more closely. It is sometimes the case that Microvellum BSB (based on BricsCAD) may have slightly lower graphical fidelity by default when working in views like 2D wireframe. This is mostly due to the default values in various configuration options within BricsCAD. To improve this graphical fidelity and make the workspace look more familiar, there are multiple options.
Use High Performance Graphics
The graphic fidelity of Microvellum BSB can be improved by setting the application to use the highest performance graphic adaptor on your device. The process for doing so can be found in this article, but for a summary:
Open the Graphics page in your Windows settings. (This can usually be found by simply typing “Graphics” into your search bar.)
Select “Add Desktop App” if Microvellum BSB is not already listed on this page.
The application can be found in the program file folder, under the file name “bricscad_bsb”. Select it.
Once BSB has been added, set the GPU preference to use High Performance graphics.
Antialiasing
Using high fidelity graphics allows one’s device to successfully enable antialiasing. Anti-Aliasing is a computer graphics technique used to remove the aliasing effect. Aliasing is the appearance of jagged edges in a rasterized image (an image rendered using pixels). The ANTIALIASSCREEN variable within Microvellum BSB can be used to gradually increase the level of antialiasing applied within Microvellum BSB, though higher settings may cause a reduction in performance speed.
By default, the variable is set to a value of 1 (no antialiasing). Raising the value, then using the REGEN command will reset all drawings in model space to use the antialiasing effect. With a value of 2 or more, jagged edges on polylines in 2D wireframe view or 2D drawings will be smoothed out. In the example image below, the difference in graphical quality between the ANTIALIASSCREEN variable value of 1 (top) and 2 (bottom) is visible, with the jagged shape of most polylines being smoothed out and much more cohesive.
Visual Style
Multiple other variables within BSB can be adjusted to set model space to look and feel more like OEM or AC. For instance, the default background color of Microvellum BSB is black (color value RGB 24,25,28), whereas the default background color in AC was a lighter shade of dark blue. This value can be altered to resemble the shade of dark blue that is characteristic of OEM and AC (close value would be RGP 50,59,72).

in the VISUALSTYLES Ui, which you must save to your template, I changed the edge color from white to RGB 120,120,120.
