Best CAD Apps – 2016

There are no limits now as to who can sketch or draw almost anything, in the advent of modern mobile phones and tablets.  CAD app makes it possible for one to experience the craft at your very own hand. This is without asking any special qualifications, either you are young or old, technical or none technical, architect or aspiring to be an architect, building engineer or a carpenter or, just any ordinary guy around. So long as, you got the right gear, the interest, and time to learn. You can draw or model like a pro with just points of a finger.

There are a bunch of 2D and 3D CAD modeling apps out there made available through the web right now. Citing few of the finest, here are the best and the most straight forward CAD apps highly commended by professionals and most users.

If you are out to learn CAD for a start, this top ten list will help you find the right app at your comfort zone.

1) AutoCAD 360


Developed by Autodesk®, Autocad 360 is a helpful app. It is designed also to eliminate some inconveniences caused by a site to office drawing routine. The app enables you to revise a sketch at hand directly on site. Thus, saves time and effort incomparable with the frequent field visits when working on a desktop in the office.

The application features the freedom to draw objects in any shape with object snap, editing tools to quickly select, rotate, move, and scale objects. The app enables you to manage layers freely for clean workflow. It is also capable of doing multi-touch zoom and pan, seamless and faster drawing. You can even use GPS to orient your position in the actual site on your mobile screen, which is brilliant.

Annotating on any part of the drawing can be easily done. You can set marks on it. Likewise, comments and even photos can be incorporated all together.

Sharing is also one of the practical features of Autocad360. Important drawings or revisions can be easily shared online. You can also plot and send it through email in pdf format and do collaboration in design feed as well.

Autocad 360 is supported with external cloud storage. Among the few to mention are, google drive, one drive, and dropbox. It also comes with the convenience of being able to edit and update external storage files at the same time. The app is also equipped with offline support. This enables your latest revised or edited a file to sync automatically once your device goes online again.

You can start learning Autocad 360 with their BASIC free plan, and try  their PRO plan free for a 30 day period. The BASIC plan remains free, but many features such as drawing and editing tools, creating a new drawing, annotation tools, layers, object properties, blocks, and priority support are excluded. Paid PRO and PRO plus plans cost around $50 and $100 per year, accordingly.

Autocad 360 is available on Apple, Android, and Windows mobile platforms. More info, and video tutorials are available on youtube on the Autocad 360 Channel

It’s currently rated 4.6 stars with just 243 users who evaluated the app to date on Google Play, and counts over 50,000 downloads, CAD Assistant is a promising new app that is worth a try.

The app mainly features viewing and converting CAD models. Very basic but effective. It is able to support shape geometry and nested compound assembly structures, colors, top level object names. It also provides file information of BRep, IGES 5.1 & 5.3, STEP AP203 & AP214 formats.

The app is designed with a tree browser. This enables you to freely navigate the assembly structure of the model in which at the same time, can also be shown or hidden for a thorough review and inspection of your model. Selected part or sub-assembly can also be queried with its properties like names and product information. Not only that, geometric attributes like area, volume, and centroid of a part can also be known just by tapping on it. Models can be saved in neutral IGES, STEP, or OCCT internal BRep format.

CAD Assistant can also view mesh models from results implemented by MeshVS component of OCCT which is incorporated in the app. Generally, for convenience and simplicity, the app reads mesh in PLY format. If you have models in mesh format, you can easily save it in PLY format and have it viewed on a tablet. Mesh data can be displayed in RGB color or scalar, as well as applied to nodes and polygons. Viewing mesh models in wireframe, shaded, and shrink modes are also available.

The app-enhanced its features with multi-touch screen capability and ability to manipulate model viewing with finger gestures. Basically, drawings or models can be rotated by just using a single finger and double for panning and zooming, accordingly.

iOS versions 5.1.1 and above(iPad & iPhone) and Android versions 4.0.4 and above are the only platforms supported with CAD Assistant.  Tablets and mobile phones can easily use the app, but it is limited only in landscape view to smartphone users.
