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

Why Use Annotations Scaling?

WHY USING ANNOTATIONS SCALING?

We often need to draw several drawings in a sheet. They often have different scales. In this situation, it can be difficult to draw the annotations. What is the text height should be in 1:10 scale? What is the hatch scale, so it is not too dense in 1:100 scale? Moreover, what is the scale in 1:5 detailed drawing?

There are workarounds AutoCAD users do over the years. The methods work, but there are some downsides. If you have the problem and are looking another way to
do this, keep reading.

What are Annotations?
Annotations are the elements that are not a part of model or geometry. We add annotations in the drawing for clarity.

  • We add text to give an object description.
  • We add dimensions to allow engineers to know the sizes quickly.
  • We add hatches or patterns to describe materials or other properties.
  • We draw tags to add legends or description

The Problem with Drawing Annotations

We draw objects in real measurements, 1:1 scale. However, the annotation size is relative. You need to make sure the annotation is readable when you plot your drawing. If you draw your annotations on model space, the problem is obvious. The text size on 1:10 scaled drawing is different when you need to plot it with 1:25 scale. The hatches can be too dense if you plot it with a smaller scale.

Another method is to draw the annotations on the layout. Because we always plot
layout with 1:1 scale, it is easier to draw annotations. We draw text with the same
size we expect to appear on the paper. If I want the text 2mm, I draw it with 2mm
height on the layout.

However, drawing annotations on the layout also has downsides. When you modify
the drawing in model space, you may need to check and rearrange the
annotations. Hatches do not work with this method.

When Will I Get the Most Benefits of Using Annotation Scaling?

If you do not use layout, then Annotation Scaling is not for you. You can fully utilize
Annotation Scaling if you use layout.

The benefits of Annotation Scaling are:

  • Annotation Scaling allows you to set the annotation size easily. You only need to think the size when it is plotted.
  • If you need to show it on different scales, you do not need to recreate it. It resizes automatically.
  • You can show annotations on different scales, but you only need to modify it once.

Excerpt from a Free e­book: Working with AutoCAD Annotation Scaling By Edwin Prakoso 




This eBook covers Annotation Scaling, how it works and how to use it. It is a 
good feature and I see several customers have implemented it successfully. 


However, there are still not many users on how to use it. Hope you will find it useful and you can implement it in your workflow. The eBook also included exercises and drawing file to use it.

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
