RapidDrawing

RapidDrawing is a lightweight Windows application built specifically for helping you create designs from scratch using different curves or apply several editing operations on a picture.

The advantages of being portable

Since this is a portable program, it is important to mention that it doesn’t leave any traces in the Windows Registry.
You can copy it on any USB flash drive or other devices, and take it with you whenever you need to draw curves on the breeze, without having to go through installation steps.

Intuitive layout

It sports a clean and simplistic layout that offers only a few configuration settings to tinker with. Files can be uploaded into the working environment using the built-in browse button, so you cannot rely on “drag and drop” operations.

Basic editing tools

RapidDrawing gives you the possibility to upload an image from the computer that can be set as your current background photo, provided that the file format is BMP.
What's more, you can export the current design to BMP file format or save it as a template for uploading it in your future projects, insert various types of lines (different sizes), and pick the color of the lines.
Other notable characteristics worth mentioning are represented by the possibility to draw straight lines, turn on or off the background display, select the pattern line, and switch to a full screen mode for a better focus on your work.
During our testing we have noticed that RapidDrawing carries out a task quickly and provides good output results. It doesn't eat up a lot of CPU and memory, so the overall performance of the computer is not affected.

Bottom line

All things considered, RapidDrawing seems to be the right choice in case you are looking for a simple-to-use tool that comes bundled with limited features for helping you draw curves.
