3D PDF Implementor Forum (3DPDF-IF) Launched

Login for•um a place, meeting, or medium where ideas and views on a particular issue can be exchanged. This past week marked a big step for the 3D PDF Consortium as we launched the 3D PDF Implementor Forum. In case you are not familiar with an Implementor Forum, it is basically a group of software vendors that work together to develop tests for assessing the accuracy and interoperability of neutral format CAD files. Other ISO standard CAD formats such as STEP (ISO 10303) and JT (ISO 14306) have similar forums in the CAx-IF and JT-IF organizations. The goal of the 3DPDF-IF is to ensure the quality and usability of 3D PDF in engineering workflows through cooperative testing. It is a neutral environment, where vendors can test their 3D PDF files to determine both the accuracy of their data translation as well as their conformance to the PDF standards (PDF, PDF/E and PRC will be supported for testing). Vendors are encouraged to bring prototype code and to use the 3DPDF-IF as part of their quality testing process. Vendors who participate in the 3DPDF-IF can use the forum to accelerate their development and testing cycles by leveraging the collective knowledge and resources of the forum. I think that it is important to also spend a minute to note what the 3DPDF-IF is not. While it is a great development and test environment, it is not a certification program. The forum does not certify, grade or rank the different members solutions. The forum is committed to ensuring the quality and interoperability of all its members solutions. All the test results are confidential...

How to set the center of rotation when viewing a 3D PDF file

When navigating a 3D PDF, there may be times when you want to change the center of rotation for the Rotate tool.  For example, when navigating around an assembly, you may want to isolate and rotate around a particular part or face.  There are a couple of ways to do this in the Adobe Reader and Adobe Acrobat, but it is not always intuitive. The easiest way to change the center of rotation is to select a part in the 3D Window or in the model tree, then right click and select Part Options -> Zoom to Part: This centers the camera on the centroid of the selected part. An alternative to this is to use the Camera Properties dialog for finer control when setting the the center of rotation. You can activate the Camera Properties dialog by either selecting the button on the 3D Toolbar: Or by right clicking in the 3D window, then selecting Tools -> Camera Properties: The Camera Properties dialog box will appear: The Alignment section of the dialog box allows you to easily set the center of rotation.  You can select a Part, Face or 3 points to define your center of rotation.  Check the Camera and Target button and your center of rotation will be changed....
