Autocad Object Grouping: Group Manager

I recently saw that you can add names to your Object groups in AutoCAD. Although, If you select the objects first and then group them, AutoCAD automatically gives them a name(numbered format) which will be categorized under unnamed groups.

How to name a group:

Select the group command from the Groups panel in the Home tab(or you can type group and enter)
> then type "n" and enter to type the name of group and enter.

P.S: the name of the group can only be one word

Advantages of using Group Manager:

I don't yet have my full hands on the group manager, but here are the few advantages of group manager which I think will be useful.

The group manager lets you change the group parameters (like rename, explode, add description)
You can also Re-Order the objects in the group in the way you want to order (though I'm not sure what's the use of ordering the group).
If you don't know the name of the group, there's also a find name button to let you find the name of the group by selecting any one of the objects in the group.
You can add & remove objects in the group.

In the following images, the rectangles are a group which is grouped by selecting the object first. So, the AutoCAD automatically gave then a name "A3" and placed then under unnamed groups category which was hidden. You can see all the existing groups in your file by checking the "include unnamed" checkbox

Re-Ordering the Objects:

If you Want to Re-Order the group objects, you can click on the Re-Order Button to open the widget which looks like the image below.

Before Re-ordering you might want to know the individual order number of each object. You can do this by clicking the highlight button.

Power Query - "SUBSTITUTE" Function: Remove/Replace multiple values in a column in One Step.

Often times, when you get data from a source, there will most probably be something incorrect that needs to be fixed using an ETL process of Power Query. And most of those transformations would require either Replacing or Removing string's that are not necessary. For example, if you extract any financial data from a source which has multiple currency symbols, there's a chance that the numbers get extracted along with the currency symbols like "$700"/"€700" instead of 700. And these type of cases makes it tough to Transform the Data to our wish as the value will be considered as a text instead of a number. In those type of cases, we would most likely have to create multiple steps to remove the multiple currency symbols from the Column. But thanks to the solution provided by Marcel for one of the questions posted on Stack Overflow, with a little manipulation of the Query language (M), we can replace/Remove multiple strings in one step using the List.

Scribble on your PC/Mac screen with these annotation tools

While you are in a presentation or hosting a webinar, you might want to write/highlight a part of your screen to draw the attention of your audience on something important. Although you can use the tools from powerpoint to scribble in the PPT file, you might want to write something on other apps as well. That's where these awesome apps come into play.

Change the orientation of Snap Grid in Revit.(Rotate Grid/UCS)(09 of 10)

One of the shortcomings of Revit is that unlike AutoCAD you can't save multiple UCS to rotate the snap grid based on the orientation of the building. But we can make use of the grid from the workplane to align/snap the elements in whichever angle you want. To see and manipulate the grid in any of the plan views, Go to the plan view. Click on "Show" button in the "Workplane" toolbar of "Architecture" tab in the ribbon. The grid by default will show up aligned to the screen orientation. You can select the grid and click on rotate to rotate the grid to your desired orientation. Snap Grid

Grasshopper: offsetting curves on surface vs scaling curves on surface

Though in Grasshopper Offset and Scale are two different node functions, when it comes to a planar surface, the results of the both are similar. But, I found the " Scale" node to be effective when you want to loft the resultant curve with another. The following images show the different results of a Voronoi structure that yielded when scale and offset nodes are used. When the Offset node is used When Scale is used
