Recently I have read that a local municipality has finally unblocked an old urban regeneration project in which I worked for many aspects. One of these was the pipe network analysis for that disused area. Fortunately I used PVnet and the job was simple. In this article I introduce this open source software and EPANET2, because its computational engine is used by the first one and it is more complete and powerful. Besides I show you that they can be installed in a Linux system using Wine.
After importing DXF in Blender, some problems start immediately because the common commands present in any CAD don't exist in Blender, or simply aren't so simply to use as in the classical drawing software. Where is the offset? How can I put the quotas? And so on... Fortunately there is PROCAD that helps the users to fix some aspects of own imported sketch. Let's see how install it and translate the UI in English.
If you need a powerful and versatile 3D software not only for modelling and texturing but also for creating interactive applications, you should have to try Blender. Sometimes its interface can appear very different and problematic than typical software, as AutoCAD for example. But with a little of settings and of course patience and time, it's possible to overcome the initial shock and to import own 2D DXF file in this program. Let's see how.
In my opinion SSAP2010 is an interesting freeware to verify slope stability and despite of other commercial softwares, it considers some inhomogeneities for example: soils, groundwater at different levels, different surfaces and stability elements (wall, sheet pile, etc.).
