Display 2D model

[Sabrinarose]

I am trying to display a very basic model 2D model but I don’t manage

source DisplayModel2D.tcl; # procedure for displaying a 2D model

#display the model with the node numbers
DisplayModel2D

You help will be very much appreciated, I have just started with open sees


And the DisplayModel2D.tcl is the one from 3D that I have adapted for 2D

proc DisplayModel2D { {ShapeType nill} {dAmp 5} {xLoc 3000} {yLoc 6000} {xPixels 512} {yPixels 384} {nEigen 1} } {

## display Node Numbers, Deformed or Mode Shape in 2D problem
## Silvia Mazzoni & Frank McKenna, 2006
##
## ShapeType : type of shape to display. # options: ModeShape , NodeNumbers , DeformedShape
## dAmp : relative amplification factor for deformations
## xLoc,yLoc : horizontal & vertical location in pixels of graphical window (0,0=upper left-most corner)
## xPixels,yPixels : width & height of graphical window in pixels
## nEigen : if nEigen not=0, show mode shape for nEigen eigenvalue
