QGIS Copy paste points from one layer to another - layer

Well I have an outline layer and a region layer.
The region for sure sure using the outline, so it would be great if I could select some important point from the outline layer and than copy paste it to the region layer.
How is that possible?

The way to go is another. Let's say we have layer outline(o) and region(r).
You create the polygon in o and after that select it. Now hit CTRL+C for copying. Now switch to r and paste it there with CTRL+V. It should be the same place now. Don't forget to disable the view of polygon from o for sure. Now in r you can use the Split Features from the Advanced Digitizing. Now split the polygon at the place where you need it. Delete the second unwanted polygon after that.

Blender CTRL+R in restrict area

Basically i want to do CTRL+R in between the edges that are in orange1 but when i do CTRL+R it creates the edge to the whole plane2 how can i make it so it only creates the edges in the area i want? I tried to change the vertices that are created in the new edges but it messes the whole plane and also I tried to delete them but as there are so many and it also deletes the faces it's not very efficient.
The loop cut tool will cut through a quad and all quads connected to its target sides.
To stop the loop cut, you want the cuts to run into a non-quad face. In the example you show, you have an ngon at the end of of the face you want to cut, I would change that so that the two faces on either side of the target face are ngons.
See that the top example will cut through connected faces, while the lower one stops in the one face.
Another option, that doesn't provide the multiple parallel cuts is the knife tool, this allows you to cut between the points you specify and doesn't continue through any other areas. You can also use the knife tool to turn the sides next to your target into ngons so that the loop cut will stop there.
To remove the extra edges that you don't want, use X->Dissolve Edges, or if that makes things collapse, use X->Limited Dissolve

How to refine some specific surfaces in Avizo?

I m using Avizo to generate a mesh of my microstructure obtained from CT scan in order to launch computations in Abaqus. I can generate interesting surfaces meshes, nonetheless outside mesh is too fine (you can see figure with this question). I am trying to create a surface path to have a coarser mesh in outside mesh but it doesnt work. When I remesh my model all is modified...
How can i generate sub-surfaces in order to specificy special mesh conditions?
Thanks for your help
It looks like your question is how can I break my mesh into separate components - perform some work on those components and then put them back together.
There is a tool to select connected components in a region in the toolbar area at the top of the meshlab window which you can use to select any triangle on the outside boundary and it will grab all the connected parts of the mesh. Then with "Filters->Mesh Layer->Move Selected Faces to Another Layer" you can separate the selected part of the mesh into a new layer. Alternatively you can use right click on the layer and select split in connected components. On this new layer you can perform simplification filters such as clustering decimation.
Once you have completed the simplification to your satisfaction, make visible the layers that you want to merge back together and use the filter "Filters->Mesh Layer->Flatten Visible Layers" to put them back together.

Is there any way to draw a line diagram using array of x, y co-ordinates in appcelerator?

If I select one of these co-ordinates, I want to highlight that point on the diagram (by a circle or whatever shape possible). Also I would like to save it later on.
I'm not sure if Appcelerator is flexible enough to do all these things (My search didn't yield much apart from here, this only supports Android), If not I'll have to generate this diagram in my webservice and pull it back on UI once there is an update in the co-ordinate array.
I've used Chartist inside a webview and it worked great. It produces a SVG graph instead of a canvas object which performs better.
If you want to use hyperloop you can use Ti.AndroidCharts

Is there an easy way to add an empty border around the entire diagram in Dia?

I'm generating a png, and the edges of the images are right alongside the outlying objects in the diagram. I'd like to add a little whitespace around the diagram. I've done it so far by adding white lines on two of the sides, but I was hoping there is a way to just specify a certain amount of padding either all the way around or per side. I don't see the setting myself.
You can draw the Standard-Box around your diagram and then just set its Draw Background property to No. Here you can layer you diagram and border box like this Layers -> Add Layer..., name the layer and now you can draw Standard-Box there.
Tip: If you don't see Layer Bar then just go to View->Show Layers.

Photoshop, merging both these layers so they look the same

Here is my little test image:

Basically they are two images, as you can see on the left is the 1st one and on the right the 2nd one. (and yes, I know one of the images has overlapped and "cut" off the wire)
Unfortunately my lighting was bad so I didnt get the same background color or this would have been easy.
But now that you see it, how do I make it so that it looks like it is one picture? (How do I get rid of that middle seam and get the same background color?)
Thanks!
you can try with this: select part one of your picture (layer) then image-->adjustments--match color then select your sorce psd (the same) and the level !
It's not always a great solution but give it a chance!
Or you can play araound with layer masks and layer effects
