What is a DAO and why does it matter to AEC?

-
Introduction Blockchain technology has revolutionized many industries worldwide, and the Architecture, Engineering, and Construction (AEC) industry is no exception. A significant innovation in this context is the DAO, which is a "Decentralized Autonomous Organization". A DAO is a blockchain-based organizational structure that operates decentralised, enabling transparent and collaborative decision-making and facilitating participatory governance. In this article, we'll explore what exactly a DAO is and why it's relevant and important to the AEC industry. What is a DAO? A DAO is an autonomous, organization-like entity that operates through smart contracts on a blockchain network. Unlike a traditional company, there is no hierarchical structure of power, nor the need for intermediaries such as managers or executives. Instead, decision-making is carried out collectively and transparently, through voting based on ownership of tokens or units of the DAO's native c...

The 5 Classes of Revit Elements

-
Classification of categories of elements followed in Revit Structure is based on their usage. 
Revit Structure uses five classes of elements:

Host
Host are elements categories that form the basic structure of a building model and include model elements such as structural walls and floors.

Components
Components are the elements that are added to host elements or act as stand-alone elements such as doors, windows, and foundations. Components are used to model building elements that are usually delivered and installed on site, such as doors, windows, furniture, and so on. Components are instances of loadable families and are hosted by other elements, which are instances of system families. For example, a door is hosted by a wall, while a freestanding component such as a desk is hosted by a floor or a level.

Annotations
Annotations are the 2D; view-specific elements that add content to the project documentation such as dimensions, tags, text notes, and so on.

Views
Views represent various orientations of a building such as plans, elevation, sections, 3d views, and so on.

Datum
Datum refers to the reference elements that assist you in creating a building model, which include grids, levels, reference planes, and so on. However they are not visible in all views, if the datum does not intersect a view’s plane (or does not intersect the plane in the correct way). Then it will not be visible in that view.

How to Save Auto-CAD  Drawing as Read Only – is quite a difficult way to answer. The only way to answer this question is by giving different options for the user to Save Auto-CAD Drawing as Read Only. Let’s see some of them below. Save Auto-CAD Drawing as Read Only Some of the different methods are listed below please choose which is appropriate in your case. Method 1 – Use Save As Auto-CAD Drawing Files as DXF (Drawing Interchange Format, or Drawing Exchange Format is a CAD data file format developed by Autodesk), by this method you actually prevent the user to make any changes to your drawing files. Making the Drawing as Read-Only Files Method 2 – Ideally you could right click on the drawing file icon (once saved), go to properties and tick read only. Ahh, well that doesn’t “lock” the drawing or anything. they can still edit it, do a Save As, or simply unchecked the Read Only option for the file once they have it. Method 3 – In case you are on a Network, you can ...

How to isolate objects and hide it. 1. Type the " isolateobjects " in the command line (without the quotes). Select the objects you want to isolate.  2. Another options select first the object you want to isolate. Right-click in the drawing area and select Isolate Objects. Only the selected objects are displayed. All other objects are hidden. 3. To redisplay hidden objects, right-click in the drawing area and select Isolate End Object Isolation. Its same process with hide object 4. Select the objects you want to hide.  5. Right-click in the drawing area and select Isolate Hide Objects.  6. The selected objects are hidden. (It’s like the command action of layoff) 7. To redisplay hidden objects, right-click in the drawing area and select Isolate End Object Isolation.  Try to save, close, and reopen your drawing, the object is still there the time you isolate or hide.  TIP: Before hiding or isolating objects, set OBJECTISOLATION...

Image
How to Slope Horizontal Steel Beam (with images) Issue: You have an existing beam that has a level as its work plane. You want to set its work plane to be a sloped reference plane, but only the reference planes or levels parallel to the beam are available when you edit the beam. Solution: To make the existing steel beam align with a sloped reference plane. Open an elevation or section view of the beam. Draw a reference plane parallel to the beam/slab using the Reference Plane tool on the Basics tab of the Design bar and name it by editing the reference plane properties. Select the beam. Click Edit Work Plane on the Options bar. Select Name and select the reference plane that you just created from the drop-down menu and then click OK. Draw a sloped reference plane using the Reference Plane tool and name it. Click Align to align the horizontal reference plane to the sloped reference plane. That's it. Bottom-line: After you made it, you ca...
