Experience your rich 3D PDF data without being tied to your desktop! 3D PDF Reader extends the usefulness of 3D PDF documents by making it possible to view and interact with 3D PDF data directly on your tablet or smartphone.

3D PDF Reader is developed by Tech Soft 3D, the company Adobe® chose as its technology partner for serving Adobe OEM developers using 3D in their applications. This means the same native 3D technology in Adobe Reader® is also in 3D PDF Reader, ensuring that your 3D content displays on mobile devices the same as on desktops with Adobe Reader.

3D PDF Reader is the only mobile application with 100% format support for the recently ISO-certified PRC format, so you can be sure that 3D content from your standards-compliant 3D PDFs display completely accurately on mobile.

Support for Views, Product Manufacturing Information (PMI), isolating and hiding parts in an assembly and creating complex section cuts make 3D PDF Reader much more than a viewer.

Key Features:
• Directly reads PDF files (3D content only)
• Supports .PRC and .U3D (3D PDF) formats
• Also supports .HSF, .STL, and .OBJ .JT, .IGS, .IGES, .STP, .STEP, .IFC, .IFCZIP, .X_B, .X_T, .X_MT, and .XMT_TXT formats
• Calculates physical properties on a per part basis
• Notes any solid geometry as precise (vs. approximate for mesh geometry)
• Uses multiple cutting planes to create complex section cuts for seeing the model’s interior
• Rotates, pans, and zooms using intuitive multi-touch gestures
• Navigates between or animates the transition between various model views
• Queries the part names of objects
• Isolates or hides components of an assembly
• Selects on PMI to determine associated features
• Loads models into 3D PDF Reader directly from an email attachment or cloud-based storage applications such as Box or Dropbox

Like previous reviewer, latest version crashes when trying to select local or Dropbox. IPhoneX: IOS 11.2.1. Turns a useful program useless



The app crashed while tapping on local or Dropbox on SE with iOS 11.2.1

Super fantastic!


The engineers send me a 3-D file, and anywhere I am in the country or the world, I can instantly review it, rotate, zoom to micro size, and hide or isolate parts and also 360° rotate / zoom these parts.

No instructions to read, it's super intuitive; with one finger drag rotate in any direction; pinch and zoom; two fingers drags the picture in any direction (which is useful when you have zoomed in very close).

On the left are a few icons that let you cut the entire object anywhere you want so you can see how the parts interact.

Then I can approve or tell them to make changes without my having to pull out the laptop. I can do this on the road, in a restaurant or anywhere I am.

This is the most productive ...and the COOLEST app! Even the most jaded tech geek looks at this in awe!

To the creators of this: two thumbs up - two high-fives - and a fist bump. ~Hal NYC
