ZWCAD Viewer

If you are creating 3D models and designs on a regular basis, then it is likely that you need a tool that enables you to view your drawing quickly and efficiently. More often than not, being able to analyze a plot from all possible perspectives can aid you to identify potential flaws that would make a model or schematic nonoperational.
ZWCAD Viewer is an application designed to help you open and analyze or make measurements on plot drawings that you have created using various CAD software solutions.

Allows you to preview both 2D and 3D models

The program comes with a fresh and intuitive interface, so it is unlikely that you can have any issues loading or previewing the plots. While you can preview 2D and 3D models, the application is compatible with only a few file formats, namely DWG, DWF and DWT from versions R12 to 2013.
It is worth mentioning that the tool includes several great tools for viewing, namely Scale, Dynamic, Realtime, Center, Object, Window or Extents to name a few. In addition, if you are working with 3D models, you can use the Orbit function to rotate the object or model at different angles.

Provides you with various measurement tools

In addition to enabling you to preview your drawing from multiple perspectives, the program comes with several utensils that can help further analyze your plot. To be more precise, the app permits you to make various measurements of the distances between objects, surfaces, regions or coordinates for instance.
Moreover, it allows you to perform layer management and it can display the details and differences between two different files highlighted in distinct colors. Therefore, it can come in handy when you are trying to figure out the improvements you or someone else brought to the model.

A handy app for analyzing plot drawings

In the eventuality that you are looking for a straightforward and intuitive utility that enables you to open most CAD-generated drawings and examine them minutely, then perhaps ZWCAD Viewer might come in handy.
