ThdCad is a vector graphics program that works in a very basic way. This CAD environment stands out for its simplicity in designing vector graphics. The platform does not have advanced options and only offers tools such as drawing lines, arrows, circles, ellipses, cones, polygons, and adding custom text. It can be used by people who are complete novices in the world of design or even computing.
Getting started
Once you install the program on your computer, you will need to create a new document. To do this, go to File and choose New. Then, to add new shapes, click Edit and select Create. There you will choose the type of shape you want to design. To incorporate the design, just drag and drop it onto the work area. The program allows you to add as many shapes as you need.
Working with shapes
In the work area, you can right-click on each drawing and enable the context menu. That menu will show options such as: Move, resize, rotate, delete, copy or change, among others.
Adding text and fonts
To add text, just click Edit, then Create and select Text. There you can write the text you want to incorporate into the interface. Keep in mind that once you have placed the text, you cannot change the font. To select a font, click the Edit menu and choose Fonts, and from the dialog box you can choose among several font types. Then you will add the text with the font you selected.
Additional options and export
Other options you will find in the platform are: Zoom, pan, move objects freely, layers option, enable or disable the grid and change the grid type. When you finish your work, you can export it in SVG, PNG (color or grayscale) or PDF format.
Conclusion
ThdCad is a very good program for creating CAD shapes in a simple way and it has some really interesting options. It is available for Windows, Mac OS X and Linux.
