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

ADDSELECTED

 Differs from COPY by duplicating only the general properties of an object. For example, creating an object based on a selected circle adopts the general properties of the circle, such as its color and layer, but prompts you for the new circle’s center point and radius.
With the ADDSELECTED command, you can create a new object with the same object type as a selected object. Certain objects have special properties that are supported in addition to its general properties, as shown in the following table.




addselected



SUBTRACT
With SUBTRACT, you can create a 3D solid by subtracting one set of existing 3D solids from another, overlapping set. You can create a 2D region object by subtracting one set of existing region objects from another, overlapping set. You can select only regions for use with this command.

Note: Using SUBTRACT with 3D surfaces is not recommended. Use the SURFTRIM command instead.
Select the objects that you want to keep, press Enter, then select the objects that you want to subtract.
autocad-subtract

Objects in the second selection set are subtracted from objects in the first selection set. A single new 3D solid, surface, or region is created.


You can only subtract regions from other regions that are on the same plane. However, you can perform simultaneous SUBTRACT actions by selecting sets of regions on different planes. The program then produces separate subtracted regions on each plane. Regions for which there are no other selected coplanar regions are rejected.
You cannot use SUBTRACT with mesh objects. However, if you select a mesh object, you will be prompted to convert it to a 3D solid or surface.

 DIVIDE
Creates evenly spaced point objects or blocks along the length or perimeter of an object.
The following prompts are displayed.
Select object to divide: Use an object selection method
Enter number of segments or [Block]: Enter a value from 2 through 32,767, or enter b
autocad-divide

Use DDPTYPE to set the style and size of all point objects in a drawing.

MULTIPLE
The command that you enter is repeated until you press Esc. Because MULTIPLE repeats only the command name, any parameters must be specified each time.
MULTIPLE does not repeat commands that display dialog boxes.
Note: You cannot use MULTIPLE as an argument to the AutoLISP® command function.
Multiple LINE
Step 1: Key in MULTIPLE
Step 2: Key in LINE for the commands to repeat
Step 3: Draw Several Lines without stopping the command

How to Save AutoCAD Drawing as Read Only

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 requ

CAD Tip Of The Day: How to isolate objects and hide it.

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 OBJECTISOLATIONMODE to 1.

7 Tips and Tricks Why Revit Structure Elements are Missing or HIDDEN

Why Missing or Hidden: It is like hide and seek sometimes you are not aware you did it or surprisingly you don't.  Unless there is a plugin that pop-ups in you Revit someone who hides your modelled element. 1. Properties--> Under Structural--> Checked out or ticked the "STRUCTURAL". It depends on the discipline you are working on in the model. This happens when the 3D model element is showing but the plan and section are missing. 2. Look or Hit the Visibility Graphics? Under model categories, Annotation Categories, and Filter. It's all there for you to check and find out. For example, steel won't show a stick symbol. Check the visibility graphics, next model categories, look at the structural framing under that tick the stick symbol. 3. Reveal or un-Hide HIDDEN ELEMENTS. It's a blue bulb icon. Under the view control bar and reveals the elements you froze before. 4. Deleted or Purged. The only way you to chase the missing element is to look
