is there a way of checking if a model is in workspace??

There is a useful function called IsDescendantOf() which returns true if the object is a descendant of the given ancestor.

if Model:IsDescendantOf(Workspace) then 
-- Code
end

~UserOnly20Charcters, Hoped I helped you to answer your question! If you have any further question, don't hesitate to comment below!!

There is a way! You have to use a loop.

Here is an example:

local modelinworkspace = false--Change this to any variable if you want

for i,v in pairs(game.Workspace:GetChildren()) do
if v.Name == "ModelName" then--Change this to your model name
modelinworkspace = true
else
print("Model not in workspace")--Just an example, this is not needed
end

Hope this helped! If it did, please accept my answer, it gives us both rep!
