[Chimera-users] Remove shapes programmatically

The “shape” command creates surface models. You can close (delete) or hide a model with commands “close” and “~modeldisplay”, respectively. You would specify the model by its ID number in the command; these IDs are shown in the Model Panel (open from Favorites menu), or to make it easier to know the IDs of each shape, you could assign the ID number at the time of creating each model with the “shape” command “modelid” option.
shape tube @ca rad 0.75 color red modelid 5
color hot pink #5
Although you can change the color, you can’t change the shape itself (radius etc.), only close that one and create another new one.
Your example command is a little strange, it just creates a cylinder between two atoms :1 at ca and :100 at ca … is that what you wanted? (you don’t need the # in that command). If so, you could do something similar with a pseudobond, which would be more manipulable, for example:
distance :5,100 at ca
setattr p label " " :5,100 at ca
setattr p drawMode 1 :5,100 at ca
setattr p radius 0.5 :5,100 at ca
setattr p color dodger blue :5,100 at ca
I hope this helps,
