PRAXIS  is a cloud-based app for sharing your product knowledge and best practices through simple, step-by-step workflow diagrams. It's totally free. It doesn't involve any Installation's, you just would need a browser (preferably chrome version 20 & later) as this is a cloud-based app.Autodesk provides us with a Getting started tutorial on their website An example of using praxis can be found in this video  where he refers to this praxis example workflow

Fusion 360 uses history based modeling techniques . This is similar to using an undo command, but unlike all other programs Fusion 360 also has a timeline which you can scrub back & forth to a particular point of your modeling. The best thing though about fusion 360 is it comes with inbuilt T-splines abilities. T-splines is one of the best plug-ins for the Rhino-3D that's used to create fluid forms. Students can get T-Splines for free from the Autodesk website An Autodesk Student expert Karam Baki  shows us how to use fusion 360 along with Revit & Dynamo to make fluid forms in our models in the following series of videos Another Youtuber Omar Mahmoud has done 2 videos in Arabic language on architectural modeling using Fusion 360 & Revit in the following videos And finally the following video shows the use of Fusion 360 for Architectural Animation

AutoCAD is one of the best CAD applications in the market. It has a wide variety of features. The more you learn the more feature you find which will definitely impress you. One of such features in AutoCAD is the QSelect tool. Qselect is an advanced version of "select similar" which lets you choose the property that you need AutoCAD to use for selecting similar elements. In Autocad, you can select objects having similar properties like layer, color, line type, transparency etc... using Qselect command. QSelect window provides you with multiple options.Once you have selected the elements, you can use filter command to further filter your selection. The following video explains the use of Filter & Qselect.

If you have a drawing in Imperial units and want to convert it to Metric, changing the dimension primary units is not gonna work ass the actual length between any two line won't change. You'll have to scale the drawing with a factor that increases the drawing size. There are 3 different ways to do it, as mentioned in Cad-Notes Scale the drawing manually  Create a new drawing with your preferred unit, then insert/bind your drawing there. Using DWGUNITS tool for Autocad 2009 & later. Scaling Manually Inch to mm To manually scale a drawing from inch to mm, you have to select all the objects you want to scale & choose a base point & specify the scale factor as 25.4  mm to inch To manually scale a drawing from mm to inch, you have to select all the objects you want to scale & choose a base point & specify the scale factor as 0.0393. Explanation  We know that to convert a drawing from mm to m, you have to scale it by 0.001(1/1000

The following link in Autodesk forum provides the solution. The different ways to Reset the text position of any dimension in AutoCAD 2015 & lower are Using the DIM command and type hometext  in the command prompt (also works with multiple dimensions) Selecting all the Dimensions you would like to reset the position, Right click on one of the grips and choose Dimension Text position>Home Text . Refer link In Autocad 2016 & later, the Dim command has been associated with a new command which lets you select objects to automatically switch between different dimension types. So, the method to reset text position in Autocad 2016 is Hovering over the text and choose Reset text position from the list of options provided. Reference  link  (this process cannot be used for multiple dimensions) To reset text position of multiple dimensions, use DIMEDIT command and select HOME from the options

Blogger is one best free platforms. You just have to have a Google ID(Gmail account) to be able to create a blogger account. It comes with few default templates & layouts which one can customize however they want. You don't necessarily have to have a knowledge of HTML &CSS languages, but having a little knowledge is going to help you in further customization . The HTML widget  lets you add any type of customized web elements like the menu bar, sidebar et.al., & the Add CSS option in the Blogger template designer lets you add style's to the HTML code. There was a Youtuber & blogger who have uploaded a good amount of helpful tutorials 2 years ago about how to set up a blog and customize it the way you want it. Though her blogger site doesn't have all the resources she presents in her video's, the video's itself are pretty helpful for a newbie. In one of her video 's, she explains in detail about how to Create Menu bar's in Blogger &

DynamoBIM Dynamo is an Open-source visual programming extension for Autodesk Revit & many other software's like AutoCAD, React-Structures etc.., similar to Grasshopper for Rhino. One who is familiar with Grasshopper would easily relate to the workspace of Dynamo. It may take a few days to get accustomed to the names of the nodes. Dynamo integrates with Revit very well that it can further heighten the already existing BIM features in it and the developers are continuing to improve Dynamo to help the users. In the gallery  section of  Dynamo, you can have a look at the work of  other users. Dynamo Studio We also have Dynamo Studio from AutoDesk which is a stand-alone programming environment that lets designers create visual logic to explore parametric conceptual designs and automate tasks. Students, Teachers & Academic Institutions are eligible for a 3-year free access to many AutoDesk Softwares including Dynamo Studio. The benefit of using Dynamo Studio i

Grasshopper is a great tool for parametric design . You can almost design anything you can think of(keeping the structural parameters aside). Especially using the Attractors- Curve/Point , one can design a flexible parametric object/structure. Louvers have always been planar- vertical/horizontal. Even though non-planar louvers have not been seen in implementation yet, I think it would be a real deal in the coming future. Non-Planar Louvers There was a post by  Kwee How  in his blog explaining "How parametric design contributes to “new” architecture and to us?" He's shown various 3D printed miniature parametric models and parametric louver is one of them. Dynamic Louvers Grasshopper Model Dynamic Louvers 3d Model Tutorial The following tutorial by Christopher McAdams  explains in detail how to design non-planar louvers in grasshopper that can be adjusted using a curve attractor. And he also explains the possible fabrication of these louvers though not i

Sketchup is an amazing 3D modelling tool. It's not just easy to learn, but also has lots of customization option and plugins that can be very helpful. Site Modelling Although you can just draw a few rectangles and lines to extrude and form a skyline or a block model, SketchUp by default allows you to interact with Google Earth , where you can find lots of existing 3d Sketchup models available for download. You can also set the geo-location of your project and select the region you want to import into your model environment. Doing this can help you in 3 ways: You don't have to worry about the scale of the site, google earth imports the site as a texture laid on a surface This can help with the existing contours of the site if any. You can use the existing models of the surroundings and without having to worry about the orientation of that model You can find the add location tool in SketchUp at File > Geo Location > Add Location, or you can use check the Go

Grouping & Scribbling in grasshopper can be helpful, especially when your document is filled with hundreds of nodes with wires going all around the screen. Often you might find it difficult to locate the set of nodes you'd like to adjust or alter for your project. So grouping the nodes and annotating the groups would be a nice idea to keep your document organised. Grouping In order to group a set of nodes, you just select them and right click on the screen(not on any of the nodes). You'll find the option to group. You can even name the groups just by right clicking on the group. Although naming the groups would be enough to identify the group. The name bubble of the group will disappear when you zoom too far out. So, the solution to be able to identify the group from a zoomed out fairly far is to add a scribble(with a text height of min 25) in the group. Scribble & Group in Grasshopper Scribble Like the name says, Scribble is just to add some notes f
