Join/Combine Regions

[ahmedshawkey95]

Hi,
How can I join multiple regions (not intersected regions) to create only one region representing them as shown below?
Input regions:

Required output as one region:

I tried to use the following boolean operation commands but didn't the required output.

Thanks,
Ahmed

Group, or block them.

No "following boolean operation commands" included.

How did you make the "required Output" portion of the drawing?

I need them to be represented as one regio entity. Other types aren't allowed.

It was a hatch and converted to a region using this Autolisp but I want to know how to do this using native AutoCAD commands.

Hello @ahmedshawkey95 

Your explanation is not clear. If I understand you correctly, (and I might not be) then you can use REGION and SUBTRACT commands.

Try this:

1. On command line=>REGION=>select all objects (1 large rectangle, 2 small rectangles and 3 circles). This will result in 6 individual regions. See image-1.
2. Without any objects selected, go to command line=>SUBTRACT=>select the large rectangle (rectangle will turn into a dashed line when selected)=>ENTER See image-2.
3. The command line will now wait for you to select object(s) you wish to SUBTRACT. Select 3 circles and 2 small rectangles=>ENTER. See image-3.
4. A single region has now been created. See image-4.
5. Hatch the NEW region and it will look like this. See image-5.

@ChicagoLooper Thanks so much. That's exactly what I was asking about.

You're welcome.

BTW, you can also use a REGION to create a viewport. Using the same operation explained in the earlier post, draw the regions directly on a layout tab so they're in paperspace, not modelspace. Then use the OBJECT option to convert the region into a viewport. 

Modelspace containing objects.

1-Objects in modelspace look like this.

While on a Layout Tab=>Layout Tab=>Layout Viewports Panel=>Object from the dropdown=>Select the Region.

2-The region is considered an OBJECT and this object can be used as a viewport.this
