XFrame2D Selection
For selecting a (big) amount of nodes or beams in one time you can use the 'Select window' or 'Select crossing'.
This works exactly the same way as you might know from a.o. AutoCAD.
You draw a 'window' from left to right. You draw a 'crossing' from right to left.
Select window'( from left bottom to the right top)
1) Determine, by the use of your mouse, the starting point of the window you want to draw. This is the left corner of the window you want to draw.
2) Push the left mouse button
3) While you push the left mouse button you move the mouse to the right. A window is drawn in (partly transparent) blue.
4) When you release the left mouse button, all the nodes and beams that are completely in this window will be selected.

Multi select
To select multiple nodes or beams you can use the CRTL-button or the SHIFT-button.
By pushing the CRTL-button or the SHIFT button continuously, you 'draw' the selection window as is described above.
