Lobsterback Duct Bends Sheetmetal Method

1 0 Beginner
This is the method I use to construct lobster back bends with sheet metal tools that I can produce flat patterns from, These flat patterns can then be used to produce files for CNC profile cutting machines. I have come across other ways of doing this using surfaces, thickened and turned into sheet metal parts. The software I am using is Alibre Design. As the version I have is low on surfacing tools I have found this a good way to model lobster back bends, which I have been involved with the design and manufacture for many years.

3D Modeling and Animation of a Spherical Robot in 3DS Max - Part I

1 0 Expert
The conceptual model creation is described in the following article: IVANOVA, Ioana and Stefka NENOVA, Computer Graphics as a Means of Increasing the Quality of Military Education, Report, Sofia: Yearbook of the Military Academy, 2013, pp. 141-155; http://rnda.armf.bg/wp/wp-content/uploads/2015/03/Binder-1-322.pdf The development of spherical robots dates back to the 1990s. Their advantage is that they move in all directions, and most often this happens with changes in the center of gravity. Some models use a system of counterweights, which helps to stay still on slopes with an inclination of 33° (Pico Rover). Some are used to study the environment, others - on the lunar surface. They are usually equipped with a high-resolution camera. The robot is tentatively named by the author VESPER-006 ("Vesper" means Venus) due to the fact that the planet Venus is a "double" of the Earth due to the close dimensions, although the surfaces of the two planets are completely different. The spherical shape was purposefully chosen to make the robot to resemble the planet it was inspired by. VESPER-006 is thought to be with an innovative design and drive method. It is suitable for research and analysis of the environment regardless of what it is (air, liquid or field). The temperature range is also wide (between -40 and +120°C). The mechanism must be able to reach the point with coordinates (x, y, z) in time space [t]. The design is stylish, simple and facilitates the rotation of the robot around its axis, as well as its movement in space. The dimensions must be such that they can take the weight of the engine and equipment. Apart from an aesthetic purpose, to make the design more interesting, the three side elements (Stands) have been added for their practical function - to stabilize the robot when it is in a static position. The main steps in the modeling process are as follows: 1. Modeling the side element: first a curve with the desired shape is drawn using Create > Shapes > Line. After that it is extruded by Modifier Panel > Extrude tool. To edit the object, right-click on it and select Convert to Editable Poly. The model can be modified by selecting individual polygons, edges or vertices and using the Extrude and Bevel tools. 2. Clone the side element: by right-clicking on it and selecting Clone. 3. Modeling the spherical body: the outer Geosphere is transformed into a grid by selecting all polygons, Inset and Extrude. The selected polygons should be removed.

Open Material Editor (hotkey "M"): the main settings of the material (ambient, diffuse, glossiness and specular level) are shown in Step 1. 2. Coloring the inner sphere: it should contrast to bring out the golden material of the outer grid. An example is given in Step 2. 3. Adding lights and shadows: this is one of the most complex stages of modeling in 3DS Max, usually done right before animating the model. It should be noted that lights can also be animated. They are selected from the main menu Create > Light. The favorite light of the author is Omni. Each of the lights can be adjusted appropriately to produce realistic shadows and highlights.
