describe it in a building application, typically we are showing where the section plane intersects the building according to some pre-deﬁned angles. But the way that you manipulate the section plane when you are looking at the 3D model is to merely pick up a section marker that moves the whole thing. The other aspect of dynamic views is that these planes can actually cut 2D geometry too. Dynamic views would not be quite as impressive if it were only a tool that you could use while you are inside MicroStation V8i. What you draw using dynamic views has to also correlate with and get created in the output. When a PDF ﬁle is created from a series of dynamic views, all of the section markers have links to the other views that are exported to PDF when you create the PDFs. Take a step back and think about your workﬂows—now you can use 2D when you want to but model in 3D in most other cases. random place on your master map. But now if you simply turn on the ‘I understand’ geo-coordinate system ﬂag in your reference attachment, MicroStation V8i takes each piece of data in your reference ﬁles and maps it into the coordinate system of your master ﬁle. All you have to do Intrinsic geo-coordination When it comes to geo-coordination, there is a similar problem of 2D versus 3D. In this case, it is the 2D coordinate systems that we use for maps and the 3D spherical coordinate system of the earth. In the beginning days of cartography, people decided that they were not going to make spherical maps. Instead, they were going to put them on pieces of paper. And the way you do that is take a section of the earth and map it to a coordinate system on the paper. Well, the paper now may be a 3D design ﬁle or have an orientation somewhere in a state coordinate system, but the coordinates transformed from the real world— latitude and longitude—to the Cartesian coordinate system is complicated. If you give me a drawing that is using one projection system and someone else gives me a ﬁle that is using a different projection system, there is no way to look at them both on the same view because there are different coordinate systems. MicroStation V8i addresses that problem. Suppose you had a project that required you to get a map of every state in the United States. Well, each state has its own projection system and if you were to attach them, they would all end up some is know the original projection and you get all your references geo-coordinated. But we all do not work on large projects that span a whole state. Instead, typically we work on much smaller things, like a city or a site. The same problem arises because you do get information like satellite or image data that is in one coordinate system and you probably want to draw your own master information in your own coordinate system. And you have to somehow get them registered properly. Through this geo-referencing technique, MicroStation V8i does it automatically for you. Everyone likes to design their buildings with their coordinate system aligned with the front of the building and the origin of the building. But when you attach it as a reference onto a map, someone has to know where to put that in the world. Well, by simply taking a few steps using a tool like Google Earth, you can get the long-lat coordinates of your site and put that into your design ﬁle. Or by using a GPS receiver, you can input the information so that your building model has all the geo-coordinated information in it. Then when you attach it as a reference, it comes out in the right place, oriented according to the proper coordinate system of the master ﬁle. This is great for you, but it is also great when you give your project to someone else and you can say, “Save it all into a single representation, all geo-referenced.” A typical example of that is sending something up to Google Earth and allowing someone else to use your design in Google Earth, all geo-coordinated and geo-referenced together. These geo-referencing, geo-coordinating tools that did not exist previously will become second nature in MicroStation V8i. “WE’RE EAGERLY WAITING to take advantage of the new Delta File Transfer technology. Preliminary testing has shown ﬁle transfer times can be accelerated by as much as 54x for large ﬁles and 3x for small ﬁles. These dramatic improvements will allow us to make more efﬁcient use of the network among our 60+ ofﬁces, and provide signiﬁcantly faster access for our external clients and subconsultants.” Mo Harmon, vice president, HNTB 12 Be Magazine | Volume 6 Issue 1 http://www.bentley.com/en-US/Promo/V8i/geo-coordination.htm
