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...

10 Productivity Tips for Everyday Cadding

-
AutoCAD has been around for a long time. Yet simply using AutoCAD every day does not necessarily make you more productive. You may not realize it, but old habits, bad habits, and  inefficient commands and techniques may be robbing you of productivity.
                                                       - Matt Murphy (4DTechnologies/CADLearning)

1. EXPLORER

I thought this command was for Internet Explorer, but it’s not. I was surprised when I type this command EXPLORER, presto it was access to the libraries e.g. documents, videos, pictures, and music.


windows-libraries
2. NOTEPAD

Type “notepad”(without the quotes) into the command line. It will prompt: File to edit. Now if you don’t know which file you want to edit just type the *. Bingo, notepad is already in front of your screen.

3. PAINTBRUSH

Create and edit drawings or images in an instant. Type “PB” or PBRUSH. AutoCAD will open its application. Even your recent edited images you can explore it.


windows-paintbrush


4. START

This command defines which application to start. Just type the START command. A prompt state “application to start”. Example for Excel just types EXCEL, for word is WINWORD and snipping tool, SNIPPINGTOOL. You can use the acad.pgp file to define a new AutoCAD command that runs an external command to start your application. 

5. SPACEBAR
      Did you know that you can:

  • stretch
  • move
  • rotate
  • scale
  • mirror
  • add vertex
  • remove vertex
  • convert line segment into an arc 


Without even typing on the keyboard and by just picking a grip. Yes, depending on where your base point is (base grip). You can cycle through these commands while on grip mode by pressing SPACE bar.
6. COPY+ARRAY COMBO
command-line

 7.  ZOOMFACTOR

 To adjust the zoom percentage, change the value of the ZOOMFACTOR system variable. The initial value of ZOOMFACTOR is 10. You can enter an integer value for ZOOMFACTOR in the range 3–100. The value you enter represents the percentage change in zoom level for each increment of wheel rotation. For example, when ZOOMFACTOR is set to 10, each increment of wheel rotation changes the zoom level by 10percent.

8. MBUTTONPAN 
To ensure the pan feature works when you depress the wheel, make sure the MBUTTONPAN system variable is set to one (1). When MBUTTONPAN is set to zero (0), you’ll get the Object Snap popup menu.

9. Command aliases 
Fewer clicks and picks are one way to productivity, but what about eliminating the number of
keystrokes you execute? Rather than typing the entire command name, you can use
abbreviations called command aliases. Many AutoCAD commands are already programmed for three or fewer keystrokes.

10.More keys to control: Love or Hate It?

People either love or hate control keys, but control freaks usually have their house in order. The importance of control keys is indicated by the presence of two of them on the keyboard! The following is a list of Control Keys defined in Windows and in AutoCAD.

CTRL+TAB     Cycles through open drawings – forwards 
CTRL+SHIFT+TAB   Cycles through open drawings – backwards 
CTRL+1    Properties 
CTRL+2    AutoCAD DesignCenter 
CTRL+3    Tool Palette Window 
CTRL+6    dbConnect 
CTRL+0    Cleanscreen 
CTRL+A    Select all 
CTRL+SHIFT+A  Toggles Group* 
CTRL+B    Toggles Snap 
CTRL+C    Copy to Clipboard 
CTRL+D    Toggles coordinate display 
CTRL+E    Cycles through isometric planes 
CTRL+F    Toggles running Object Snap 
CTRL+G    Toggles Grid 
*CTRL+H    Toggles Group  
CTRL+J    Executes last command 
CTRL+K    Insert hyperlink 
CTRL+L    Toggles Ortho on/off 
CTRL+T    Toggles Tablet mode

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 ...

CAD Tip of the Day: How to Assign the Find Command to Ctrl+ F

How to Assign the Find Command to Ctrl+ F (a step by step guide) Just about every Windows application you own—Word, Excel, Notepad, your browser—uses Ctrl+F to launch Find… except AutoCAD®.  Hit Ctrl+F in AutoCAD and you get … .  Really?  Because F3 wasn’t sufficient? So let’s say we set Ctrl + F to be the Find command! How to Assign the Find Command to Ctrl + F:  Open the CUI dialog box by typing CUI at the command line.  Under Customizations in All Files, scroll down and expand Partial Customization Files, then expand Custom.  Now expand the Keyboard Shortcuts node.  Under Command List, drag the Find command up into the Customizations pane and release it next to Shortcut Keys to add it to the listing. MEMO:  If the recently added command does not initially appear in the Shortcuts pane over on the right, click OK out of the CUI, then re-open it and navigate back to the Keyboard Shortcuts node under Custom.  In the Shor...

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 ...
