Free CAD Software
Jörg posted a topic in General ModelingHi together, The software CAESES is a CAD and optimization platform. For students and PhD students there are free non-commercial licenses available. In addition, there are low-price offers for start-ups and smaller companies. CAESES can be used for 2D and 3D parametric modeling, see this link for some information about its CAD capabilities. Here are some screenshots: Compared to traditional CAD systems, CAESES is a bit different. It comes with a strict object-oriented approach, i.e. the user sets up dependencies between objects and these dependencies are then kept. This makes it easy to automate the geometry generation process. Here are some features of CAESES: Full 2D and 3D modeling capabilities (NURBS-based)Roughly 20 curve types and 15 surface typesStandard transformations (translation, rotation, scaling)Writing of custom features and functionsBoolean operationsTrimmingFillets between surfacesMorphing functionality for deformation of existing geometrySurface tessellation control through e.g. trimesh objects to create and fine-tune custom STL dataCommon import and export formats e.g. IGES, STEP, PARASOLID, STLIndustry-specific modules for blade and ship designBatch mode for non-GUI (hidden) geometry generation in the background Cheers Joerg LAST UPDATE: NOV 2017
Multi Segmented Smooth Curve
Mr. Ashesh Pradhan posted a topic in General ModelingWe can make a multi-segmented smooth curve from Feature Definitions -> Hull Design -> Multi Segmented Smooth Curve. The issue is I can only define '2' intermediate points in a curve. I want to join many multi-segmented curves to create a single curve. How do I do it ? I am a beginner in CAESES. I could not find it in documentation. Please help.
Skinning Method of Meta Surfaces including Boundary Curves
Jörg posted a topic in General ModelingHi together, With version 3.1, you have the additional skinning option for meta surfaces. This allows you to have a low number of generating cross sections (curves in surface direction) while matching given boundary curves, also called rails. See the attachment for a simple example. In former versions, one solution to approximately match such boundaries has been to increase the number of cross sections - which is expensive and increases the data of the resulting NURBS surface. Here, this new skinning method is a good alternative to the existing auto-cubic point interpolation. Finally, when it comes to the new BRep type that also comes with version 3.1, it is even recommended to exactly match boundaries for further processing such as Boolean Operations and fillet modeling.

General Documentation about Curves, Surfaces etc.
Jörg posted a topic in MiscellaneousJust a little but helpful thing: In order to get the type documentation of an object in your project (such as points, curves, surfaces), click on the icon in the object editor: This opens up the documentation browser and shows information about the type. Quick and easy... Cheers Joerg
