In Part 5 of my series on вЂњWhatвЂ™s New In Solid EdgeвЂќ I mentioned that Solid Edge ST3 boasts of вЂњ more than 4 times faster graphics performanceвЂњ. As you can see towards the end of the video above the time lag is just too large. The shaded model with edges shows up fine, but the response is quite slow. Solid Edge was a bit of a disappointment. Also the response is a big slow as well, even slower than that of Alibre Design. In such cases it would help to use the technique used by CoCreate Modeling and KOMPAS-3D and show the shaded model only. The problem is that when the graphics pipeline reaches it limit the edges are calculated by using a very loose tolerance, which gives rise to those awkward wireframes that you see in the video. Now you may look at the above video and think that RhinoвЂ™s graphics is not designed for large models. It simply shows the shaded model only.ДЄs expected, the navigation is state of the art. Like CoCreate Modeling, KOMPAS-3D does not bother calculating edges when the user is navigating. In this video you can see the technique I mentioned above more clearly. As you can see the response time is great. I must say KeењњreatorвЂ™s graphics performance is much better than I expected. Frankly, IвЂ™m not surprised since Autodesk did some really nice stuff to InventorвЂ™s visualization in 2011. If you didnвЂ™t notice it, hit Replay and look more closely. If you look even more closely, you will notice that when the graphics engine so overburdened that cannot even display a shaded part, it displays a shaded bounding box in its place. If you look closely, the edges are hidden during the navigation and displayed once again when navigation ends. CoCreate Modeling is one CAD system that uses the technique I mentioned in the case of Adobe Acrobat above. A number of surfaces were imported untrimmed. The navigation is still a bit sticky for large models like this one.ДЄs you can see CoCreate Modeling messed up the STEP file import. But I believe there is some scope for improvement. They had mentioned improved graphics performance for large models was one of the enhancements in V12 and it shows.

This is a technique commonly used in CAD software and someone needs to tell Adobe that such a thing exists.ДЄlibre Design does a good job showing the model with edges turned on. When user stops navigating the edges can be calculated and displayed. So instead of showing these stupid wireframe bounding boxes, they could show the entire model without edges while the user is navigating. If you turn off edges the model shows up nicely. Acrobat displays what is could calculate in the given time and resources and shows wireframe bounding boxes for what it could not. Here is a series of videos showing me navigating around the model of the engine in each CAD system.ДЄs you can see, it look horrible. One of these days, I need to figure out why. I wanted to add IRONCAD to the list of CAD systems but could not because for some reason on my computer it crashes on start up. However, I thought it best to do this in order to avoid giving a particular CAD system an undue advantage or burdening another with some residual hard disk activity. This may not be the case in a real world situation since users really donвЂ™t wait for their systems to come to rest before starting a large operation. Its displaying the edges that puts an extra load on the graphics pipeline and that is precisely what I wanted to compare.Д«efore performing each test I ensured that the system had returned to its idling state. Displaying a bunch of colored triangles is the easy part and all CAD systems can do that. The only setting I did change was to turn on the display of edges if they were turned off by default. Actually, I make it a habit to avoid messing with the default settings of a CAD system because as a start I need to check if my plug-ins work well with them in their default state. Although I understand that the number of triangles can affect performance, I didnвЂ™t consider that to be something I needed to bother myself with because I assume CAD vendors use optimum tessellation settings as the default when shipping their software. Other CAD systems may have tessellated the model differently. SolidWorks supposedly used more than a million triangles to represent it.

To do the comparison I decided to load a 45 MB STEP file of a highly detailed engine and 3D orbit around the model. It has a blazing fast 250 GB solid state hard drive, 4 GB of RAM and sports a NVIDIA Quadro FX 2700M graphics card with half a gig of memory on it. Today I finally managed to do something that I have been wanting to do for quite a while now вЂ“ compare the graphics performance of all the CAD systems installed on my Dell M6400 mobile workstation.
