CAD Forum - Freeware application for digital terrain modelling (DTM) in AutoCAD.

Xanadu DTM is a freeware application for 3D terrain modelling in plain AutoCAD . You can use it for visualizations and simple terrain calculations and analysis. The application is based on a TIN generator by D. Piazza and contains enhancements and functions from the Xanadu 's application GEOsurf. DTM allows to generate triangular terrain model (3DFaces) from any 3D points (objects) or contours in your DWG file. With this model you can then perform other operations - e. g. calculate volumes (above/below a reference plane), estimate point elevations on the model, generate flowline You can also use a generator of random 3D terrains. (For advanced terrain modelling functionality we recommend to upgrade to AutoCAD Civil 3D.) More information on www.

3d Cad Software

Features 3D CAD Software Microspot Interiors Professional is a professional interactive 3D modeling application and 3d CAD software for Mac that makes it simple to create and render your model and view the results as you are working. 3D CAD Software for Mac Microspot Interiors Professional is the award-winning software which enables professionals and novices alike the ability to create 3d interior designs in little time and without a steep learning curve. With Interiors Professional, you can create your own furniture, accessories, lights, shading, interactive videos and more. Interiors Professional comes with a powerful modeler that allows you to create items, or you can use the ever expanding Microspot library that comes packed with different items - just drag an item into your creation and save it. Model your own furniture Interiors Professional takes interior design to a whole new level with a host of modeling tools. It contains 14 modeling tools and four modeling palettes. The tools include 6 primitive shapes, cube, sphere, cone, pyramid, cylinder and regular polygon and four more complex tools for pipes, torroids, lathed shapes and irregular polygons. The other tools include a 3D Text tool and an edit path tool which enables coils and threads to be modeled. The extra palettes include a section palette for adjusting the section of lathed objects, polygons and many more, and a construct palette for boolean operations. Adding a touch of rendered realism Once you have finished working on your design in Interiors Professional, the final stage will be to render the model to show shadows and lighting but also to anti-alias(smooth) the scene when ready for high resolution export. For this we provide the Microspot Renderer .

Daily Autocad » Blog Archive » Arc drawing techniques in AutoCAD

« Dimensioning: _DIMJOGLINE My first VBA application in AutoCAD » Arc drawing techniques in AutoCAD 23 November 2007, Friday 7:21 Print This Post  Orhan Toker Architect Autodesk Authorized Consultant Database Specialist All AutoCAD versions Hello Daily AutoCAD readers, In this article, I will try to explain about arc, which is probably one of the hardest entities in AutoCAD to draw. The reason why I have chosen this subject is that probably this will be one of the main subjects which advances an AutoCAD user to one upper level. Moreover, subjects of correct coordinate and unit entry, drawing perpendicular and parallel and developing of drawing techniques in AutoCAD will also be explained within this article. I guess, the first entity that you learned to draw in AutoCAD is ARC. However, as I don’t know how you are going to use the arc entity, so I will start by explain ARC drawing methods. Because, after introducing the ARC subject, you will see that in addition to 9 different ARC drawing methods that is generally known by users, there are 4 other methods, which I believe will be very useful for you. Fig. 1 Structure of an ARC entity First of all, I would like to start by explaining about the structure of ARC entity. ARC is a circle part that passes through 3 points. Thus, 3 points are enough define an ARC. When you enter ARC command in AutoCAD, unless noted otherwise, you can draw an arc by entering start point, middle point and end point.

AutoCAD 3D Modeling Courses

Learn 3D Modeling in AutoCAD My name is Lars Nielsen. Welcome to my site. I been searching the Internet to find interactive elearning courses. I did not find any for AutoCAD. So I decided to create elearning courses for AutoCAD. Many of you have learned 2D drafting in AutoCAD. But have you ever desired to learn 3D modeling in AutoCAD? If the answer is yes, then you have come to the right place! Now you have the chance to learn 3D modeling from an experienced AutoCAD user. I have created the elearning courses, with the thought that you should get the best possible learning.
