Evolution of Construction Docs

Some historians consider this 9th century drawing as the very beginning of the history of blueprints. The documents that emerged from the Renaissance era look more like modern blueprints than the ones from the Medieval Period. Until the mid 19th century, architects relied on skilled draftsmen to faithfully copy their drawings for distribution. However, enter the era of specialized architectural tools and draftsmen were then able to produce drawings more accurately and more productively These documents actually obtained their trademark blue in 1842 when John Herschel discovered the cyanotype process. Artists and scientists quickly adopted this new way to reproduce notes, efficiently and at a lower cost than previous methods available. Preserving the silhouette of leaves, ferns and other botanical samples were easier than ever. Aniline prints Cyanotypes Diazotypes Electrostatic prints Ferrogallic prints Gel-lithographs Hectographs, (handmade) Pellet prints Photostats Sepia prints Silver halide prints Stencil duplicating (mimeographs) Spirit duplicating (hectographs, machine made) Van Dyke prints The end of the 20th century saw the development of computer-aided drafting (CAD) technology and large-format printing processes that made the reproduction of multiple accurate copies of the architect’s original design easier than ever. Neolithic, also known as the New Stone Age, was a time period roughly from 9000 BC to 5000 BC named because it was the last period of the age before wood working began. The tools available were made from natural materials including bone, antler, hide, stone, wood, grasses, animal fibers, and the use of water. These tools were used by people to cut such as with the hand axe, chopper, adze, and celt. Also to scrape, chop such as with a flake tool, pound, pierce, roll, pull, leaver, and carry.

Why VR? Progression! Mockups Prototyping Paper Layouts 3D models
In manufacturing and design, a mockup, or mock-up, is a scale or full-size model of a design or device, used for teaching, demonstration, design evaluation, promotion, and other purposes. A mockup is a prototype if it provides at least part of the functionality of a system and enables testing of a design.

Enscape Devices Oculus Rift HTC Vive Gear VR, Cardboard Capabilities
Direct VR Integration in CAD software 360-degree panorama picture Oculus Rift The Oculus Rift is the head-mounted display (HMD) that is currently supported by Enscape. The Oculus is one of the first and most widely used HMDs worldwide. The final version runs with a resolution of 2160×1200 pixels. This is the preferred Enscape solution, since it runs in similar quality as the vive at a lower price. HTC Vive The HTC Vive is also supported in Enscape. The resolution of the screens is comparable to the Oculus Rift. The Vive comes with great positional tracking, meaning that the user can actually move naturally in an area of 15 feet by 15 feet (5 m × 5 m). This is a great advantage and at the same time a disadvantage as it needs to be installed in a certain area to get the most out of this technology. Gear VR, Cardboard With Enscape, you can export Panoramas which then run on Google Cardboard or Gear VR. They can easily be opened using a web browser. Enscape does the hosting and uploading for you automatically. Direct VR integration into CAD software Enscape falls into the category of a direct integration into a CAD software. There are several solutions on the market that are specialized in architectural VR. However, Enscape is the only one that is directly integrated into the CAD software. The integration enables a direct experience of the CAD-model with only one click. This sort of virtual reality application is very demanding for the hardware but delivers great results without additional effort. As a result, this is the preferred solution for all use cases, as you can use a computer, do not have to wait several weeks and do not have to spend a five-figure amount to create a walkthrough. Additionally, the ease of use marks the integrated visualization, like Enscape, as the solution with the greatest potential for the future. VR with a game engine CAD models can also be exported into rendering engines that are known from computer games industry. The advantage of this solution is the quality, which comes close to the quality of a photorealistic rendering. However, the process of creating such a virtual reality walkthrough demands skill and effort as well as time. This results in much higher prices. 360-degree panorama picture Some VR users are interested in sending a high quality picture to their clients. For this the best option is to export the CAD model into a 360° panorama. However, the disadvantage here is that the view is not flexible, as the model needs to be exported and only distinct spots in the project are possible to view. All devices but especially Google cardboard and the Samsung Gear VR can run this sort of VR application. Enscape currently does not support this feature. If you want to see this feature in Enscape, feel free to vote for it on our development agenda:

Augmented Reality Augmented Reality
Hololens (SketchUp) or Smart Phone (SmartReality) Smarthelmet (DAQRI) Safety glasses that contain augmented reality features “Augmented reality in construction and architecture projects involves placing a 3D model of a proposed design onto an existing space using mobile devices and 3D models. AR has been used in the video gaming and media entertainment for a much longer period of time to show a real image interacting with one created from computer graphics. Its utilization matured in the AEC industries in the past five years when contractors such as Seattle’s BNBuilders began using it to show clients proposed designs in the context of existing conditions using iPads and other mobile devices on a construction site.” Jeff Yoders The technology has advanced enough to where implementing it is a lot easier and cheaper “Seeing a Revit or other 3D model in context greatly assists in space planning and design visualization. Augmented reality was confined mostly to AEC firms that had large technology groups who could spend hours integrating Revit models with homemade 3D game engine models, but the technology has now been democratized and is available on a per-project basis, so small firms and even sole proprietors can take advantage of it.”
