How to select an entire "sub"-object in Edit mode when two meshes have been joined?

Sorry if this common sense or has been answered, I have also not been able to find a satisfactory answer to this question.

I got my start in 3DS Max before switching to Blender. In Max, when you join two meshes, you can enter Edit Mesh/Edit Poly mode, which is the equivalent of Blender’s Edit mode. However, in Max, in addition to Vertex-Edge-Polygon selection, you also can select Face (which I have found pretty useless, it’s like selecting one of the two triangles that make up a quad polygon), or MUCH more importantly, you can select by OBJECT. What this means, is that if you have joined two meshes together, in Edit Mesh/Sub-Object selection, you can select one of the ENTIRE joined objects with just one click!

In Blender, I have been having to use workarounds. Frequently, I can use Island Selection (Ctrl-I, or Ctrl-L, i forget which at the moment), and I imagine this will be people’s immediate response to this question. However, this is NOT sufficient. This only works when the two joined meshes DO NOT overlap. If they DO overlap, using Island Selection will in fact select BOTH joined objects. As a work around, I have to select a vertex specific to my desired sub-object and then grow the selection (Ctrl-+) until I have the entire thing selected. But this is incredibly tedious, ESPECIALLY if the joined object has many, many vertices. I can easily waste my time having to press Ctrl-+ 20 or 30 times.

Question: In Edit Mode, is there a way with one-click or one keyboard shortcut so select an entire sub-object, a complete mesh that has been joined to another mesh, in the same way that 3DS Max has sub-object > object selection? Specifically, Island Select does not work with overlapping meshes. Is there another keyboard short-cut to select an entire sub-object, or is there a way to make Island Select work for overlapping meshes?

Thank you!

I’m not sure what you mean by overlapping meshes.
Ctrl+L just selects linked vertices. If you have meshes overlapping each other it doesn’t matter as long as they are not physically connected. The alternative is to press L with the cursor next to a vertex.

If this does not work for you show us something that clearly demonstrates what you want and what you don’t want - screenshots before/after and example blend files.

I may have figured it out.

It was the difference between pressing “L” and “Ctrl-L”.

By pressing L, which the Spacebar Menu says is “Select Linked”, what actually gets selected is dependent on the location of your mouse cursor. So even if I select a vertex way off to the side where there is no overlap with another mesh, if my mouse cursor is over another part of the joined mesh when I press “L”, that whole other object gets selected.

But, pressing Ctrl-L is working just fine no matter where my mouse cursor is…I wonder why I was having so much trouble before? Hmmm…well, at least I figured something out. Thanks for your help, Richard.

Please don’t uppercase normal words, it’s annoying. You’re already making your long post(s) easier to read with paragraphs, don’t ruin it with unnecessary uppercased words. It doesn’t help to read or understand it any better, on the contrary. If you want to emphasize something, use images - Those get the point across more effectively and you don’t have to write as much text.
