Can't delete viewport frame to make custom one

[NarkDuffy]

Hi I am having issues with creating viewports in the attached file. When I open the layout, say layout 3, it shows the viewport frame but I cannot highlight it in order to delete it. This is a setting in this file I have inadvertently turned on or off. I have created a new file, done a scribble, opened a layout and deleted the viewport. I have googled for a solution before asking the forum and it is most likely very basic.
Any help appreciated as I have very little hair left.

It's saved in 2013 so I can't open the file. Have you turned on all the layers before you tried to select? Are any layers locked? Including Defpoints and 0? It may sound strange but its one of AutoCADs quirks...

I was able to open your drawing. I went to Layout2 and erased the viewport frame with no problem. I also created a new layout and was able to erase the viewport frame from that as well. If you don't want AutoCAD to automatically create a default viewport each time a layout is created then disable the feature.

Why do you have Blipmode turned on? Don't you find that distracting?

If you clip the viewport, you may have the boundary polyline on one layer and the viewport itself on another. Turn on all the layers and see if you can select it.

Do you know that you have a viewport on a layer named "Y Dimensions"? And you have this layer turned off? Why? You have a layer called Viewports too. Doesn't it make sense to pur your viewports on the Viewports layer?

You have a number of lines that are drawn at very slight angles. While they may look straight when zoomed out as you get closer you notice they are not truly horizontal. You also have some ninety degree corners that do not meet up.

Why is some of your hatching on the Section Cross Proposed Balcony layer? Seems a bit unusual.

Do a Zoom > All. You have some objects that are way, far out from the bulk of your model space objects. Is this intentional?

I ran the OVERKILL command on the main group of objects of which there were over 5000. AutoCAD found 168 duplicate lines; it also found 421 instances of lines that overlapped each other. This could cause you some problems down the road and should be addressed now.

I drew a white circle around the far out objects in model space and a rectangle around the group of objects that include your house just so I could point them out easier to you. You should erase the objects I circled.

Would you look at that. After I erased the objects in the circles I found two more areas where other miscellaneous objects/geometry got thrown off into outer space. You'll have to find and erase them too.

Your Section Cross Proposed Balcony Notes seem to be on the Section Cross Proposed Balcony layer. If you don't need the "Notes" layer it can be deleted unless of course you really wanted your notes to be on a layer separate from the geometry they are describing.

You have two front elevations of the house. The hatching on the upper portion of each house is on Section Cross Proposed Balcony layer. Since these are elevations and not sections is the hatching on the wrong layer?

There are numerous little "orphan" line segments floating about your drawing. These should be cleaned up. Maybe they were left over parts of a previous design that you decided not to use?

Oops...looks like that bottom elevation of the house has the hatching on two different layers. One of them is called Section Front and the other is the Section Cross Proposed Balcony layer. None of your elevations should have layers with the word "Section" in them.

Just a preliminary design review. No sense repeating mistakes.

Thanks to everyone.
I will save in 2010 in future.
For all the other points i may have this or that on or off without knowing it.
I will now go through all your notes.

Again thrilled at the level of assistance. Thanks Thanks
