Programmatically connect SimScape blocks

I am connecting simscape blocks programatically.

add_block('fl_lib/Electrical/Electrical Elements/Resistor','mymodel/Res1');

set_param('mymodel/Res1','position',[140,80+40,180,120+40]);

add_block('fl_lib/Electrical/Electrical Elements/Capacitor','mymodel/Cap1');

set_param('mymodel/Cap1','position',[220,80+80,260,120+80]);

set_param('mymodel/Cap1','Orientation','down');

add_line('mymodel','Res1/Rconn 1','Cap1/Lconn 1');

add_block('fl_lib/Electrical/Electrical Elements/Electrical Reference','mymodel/Ref1');

set_param('mymodel/Ref1','position',[220,80+160,260,120+160]);

add_line('mymodel','Cap1/Rconn 1','Ref1/Lconn 1');

% set_param('mymodel/Ref1','Orientation','down');

add_block('fl_lib/Electrical/Electrical Elements/Resistor','mymodel/Res2');

set_param('mymodel/Res2','position',[220,120,180,160]);

add_line('mymodel','Res1/Rconn 1','Res2/Lconn 1');

by changing the value of the position of the Res2 I am having the issue:

set_param('mymodel/Res2','position',[220,120,180,160]);

> In new_model (line 12)

Error using new_model

Invalid setting in Resistor block (mask) 'Res2' for parameter 'Position'

Caused by:

Error using new_model

Invalid definition of rectangle. Width and height should be positive.

Can you advice what can be an issue?

How can I connect the Res2 to the Wire instead of connectting directly to the output of Res1?

How can I amke the graph wiring stright, aligned programatically?

set_param('mymodel/Res2','position',[220,120,180,160])

is wrong. The third number (180) needs to be greater than the first number (220). The command needs to be something like

set_param('mymodel/Res2','position',[280,120,320,160]);

Adjust the parameters for the y-coordinate will made the wiring straight. For example

set_param('mymodel/Res1','position',[140,85+40,180,125+40]);
set_param('mymodel/Res2','position',[280,125,320,165]);
