Autodesk AutoCAD (Windows/Mac). Programmi per disegnare in 3D. AutoCAD non ha bisogno di troppe presentazioni. Si tratta del software CAD più famoso al . Home Design 3D Gold è l'ultima versione di una applicazione Mac che permette di progettare case o studiare una diversa sistemazione.
This can also happen if you had an older version of FreeCAD installed, and you upgraded to a newer version. In that process, the configuration files of FreeCAD might have been corrupted for some reason, and now FreeCAD cannot read them anymore, and fails to start. The solution is simply to delete these configuration files, so FreeCAD will recreate them on first run. There is a Macro findConfigFiles available to help in locating your configuration files.
It can be installed using the Addon Manager in the Tools menu. The macro will find your config file folder, copy it to the clipboard, and attempt to open that location with your default file browser. It makes no changes to your files or settings.
FreeCAD is open-source software , and is free not only to use, for yourself or for doing commercial work, but also to distribute, modify, or even use in a closed-source application. To summarize, you are free to do almost anything you want with it. See the Licence page for more details. From the right button mouse. FreeCAD has several different navigation modes available, that can be set in the preferences settings dialog or changed by right-clicking in the 3D view. For full details about the modes, see the Mouse Model page. For the default mode "CAD Navigation" , the commands are as follows,.
Holding down Ctrl allows the selection of multiple objects. The cursor location when the middle mouse button is pressed determines the center of rotation. Rotation works like spinning a ball which rotates around its center. If the buttons are released before you stop the mouse motion, the view continues spinning , if this is enabled. With this method the middle mouse button may be released after the right mouse button is held pressed.
Head to the Getting started page for a quick description of the tools you can use. There is also a new Tutorials section containing a few resources. Note that since FreeCAD is relatively new, its user interface is still very bare and doesn't feature many tools.
Clicking the middle mouse button re-centers the view on the location of the cursor. There's a message with a page for tutorials - try it, it's dead. Some specific file formats such as Collada or DWG also require extra components, which cannot be bundled into FreeCAD, and must be installed by yourself separately. To change whether rows or columns are plotted as series, choose an option from the pop-up menu in the bar at the bottom of the window. This wiki is hosting a lot of contents. Matrix stop with the fake reviews all with 5 stars.
But much more advanced functionality is already available to you from python scripting. There is at the moment still little documentation for beginners, unfortunately, but the Tutorials section contains some pages to help you getting started. Maybe your questions are already answered there. The theory is simple: Lines or wires , when extruded, form faces.
Faces, when extruded, form solids. If you extrude something and the result is not a solid, then the something was not a face. If you have lines and you want to extrude a solid from them, you must first select lines that form a closed perimeter select several objects by pressing Ctrl , join them into a wire Upgrade tool , then make a face from that wire Upgrade tool again. There you are, if all went well you can now extrude it to a solid. Now, there can be many little twists that make you obtain the wrong result.
The best way to make sure is to check what's inside the object you are extruding. Objects contents can be easily explored with python. Assuming for example you have an object called "Wire", you could type this into the python console:. The above code retrieves the shape from an object, shows the faces and wires your object has if any , and, if there are wires, prints if those wires are closed.
If you don't have any face, you won't get a solid.
If there is no closed wire, it won't become a face. If you are interested, there is more info about what you can check with python on the part scripting page. If you cannot join several lines into a wire, the most probable cause is that their endpoints don't meet, there must be small gaps between some of them.
There, I'm afraid, my experience tells me the quickest way would be to redraw a wire on top of them. Indeed the boolean operations fusion, subtraction, intersection are not its best features, and often give strange results. This is a current limitation we have no way to solve at once, so your best path is to try obtaining the desired result by modeling another way.
For example, problems with primitives such as cylinder can often be solved by using an extruded circle instead. Coplanar surfaces between parts can cause trouble, as well as surface tangency.
As a general rule, if a shape doesn't work, try remodeling it a different way. If the model is of one single item, try selecting only the newest item usually the last one in the hierarchy tree. As we create a model in the PartDesign Workbench , each feature takes the shape of the last one and adds or removes something, creating linear dependencies from feature to feature as the model is created.
We also support flowcharts, mind maps, org charts etc. Considering the fact that there are many glaring mistakes that are present when it comes to sequence diagrams, we have decided to gauge and mention ten of the most common mistakes you are sure to make. While we discussed about how to reference another sequence diagram via sending across data through parameters and also return values.
