What is a CAD drawing?
A CAD drawing is a digital design or blueprint created using computer-aided design (CAD) software. It represents objects or systems in two-dimensional (2D) or three-dimensional (3D) space and is widely used in fields like engineering, architecture, and manufacturing.
2D CAD Drawing
A 2D CAD drawing is a flat representation of an object or design. It typically includes details such as dimensions, annotations, and layers for organizing information. In GstarCAD, users can create highly precise 2D drafts for construction plans, mechanical parts, and electrical schematics. Tools like Line, Circle, and Dimension make it easy to draft detailed and accurate designs.
3D CAD Drawing
3D CAD drawings provide a more comprehensive view by visualizing an object in three dimensions. GstarCAD supports 3D modeling, allowing users to create realistic shapes, surfaces, and volumes. Features like Extrude and Revolve help transform 2D sketches into 3D models, useful for product design and simulation.

Q&A: CAD Drawing Software related Questions and Answers
How to convert image to CAD drawings?
To convert an image into a CAD drawing, follow these general steps:
1. Choose Software
Select CAD software that supports image-to-CAD conversion, such as GstarCAD, AutoCAD, or specialized tools like Scan2CAD.
2. Import the Image
In your CAD software (e.g., GstarCAD), import the image (usually in formats like JPG, PNG, or BMP) using the "Insert" or "Attach" command. Place the image in the drawing space.
3. Trace the Image
Use the CAD software's drawing tools (like Line, Polyline, or Spline) to manually trace over the image, creating vector lines that replicate the key shapes and details.
4. Vectorize Automatically (Optional)
Some software, including GstarCAD with plugins or third-party tools like Scan2CAD, can automatically convert the image into vectors using a process called vectorization. This converts raster pixels into editable CAD entities (lines, arcs, etc.).
5. Edit and Save
After converting, refine the CAD drawing by editing the vectors, adjusting scales, or adding dimensions. Save the file in a DWG or DXF format for future use.
