I need to import and plot a few .stl models in a single figure. I am able to do so using pdegplot and hold on commands

model = createpde;
importGeometry(model,'./FullModelBase2.stl'); % binary model files available in attached zipped folder 
pdegplot(model,'FaceLabels','off')
hold on;
model2 = createpde;
importGeometry(model2,'./FullModelBase1.stl');% binary model file
pdegplot(model2,'FaceLabels','off'); hold off;

but with each plot the basis of 3D coordinate system is also displayed as shown in figure. Laborius and difficult way is to delete them by manual selection and delete key. I am not able to find any property name associated with it, which can be used in script to automate this task. Is there any alternate way to do so? I have attached the zip file containing .stl files that can be used to try.

b=findobj(gca,'Type','Quiver');

Now b has the property of both Quiver. set there visibilty to off or whatever you want (use set for that purpose)

It still has the text x y z

c=findobj(gca,'Type','text');set(c,'String','');

But it will also remove any other text type you have in figure. so

findobj(gca,'String','x','-or','String','y','-or','String','z')

will give you object with string equal to x or y or z

i dont know why it is not working on 2020a and 2020b (it is not considering Text as object). Just set the visibility of Text object manually

a = gca;
disp(a.Children)

and change the visibility of text object manually to 'off'

I think this issue may be caused by the MATLAB version. It works well in 2019a.

In Matlab 2022b, you can remove the quiver and axis labels with this method:

% Find the quiver object
originQuiver = findobj(gca,'Type','Quiver');
% Turn off the visilility of the quiver
set(originQuiver,'Visible','off');
% Turn off the visilibty of the text on the middle layer (x,y,z labels)
set(findall(gca,'Layer','Middle'),'Visible','Off')
