Bike Frame Sample Bugs

[GreenRoomTech]

Hi, Total Noob here. When taking my course in F360 it showed the "Isolate" feature. So I tried it out on the Bike Frame sample. When I isolate an assembly such as the shock as soon as I unisolate it the rear triangle  goes to a flat set of planes instead of back to the original shapes. I am a professional dev so I tried it several times in different ways and its easily reproducible. If I do a save as it even saves the objects in that state and rehydrates them from a saved file that way. The second bug is that when I animate/move the triangle the shock over extends and pierces through the frame instead of stopping at a contact point. This may be expected behavior of a drawing without a properly set extent but its surely not as the sample was intended. I also randomly had the pin/bolt from the shock relocate in space but that one I can't easily reproduce. If this is just my noobness talking please excuse me, just thought I would bring it up.

Hi,

I think you should create a separate thread for each problem.

For this, movement limits must be defined.
Joint > Right click > joint limits

You are opening a assembly model from the Design Samples folder.  This folder is Read Only to you and unless you save as to a folder of your choice, you have no control over the features and bodies that will display when you do an Isolate and Unisolate on a component.  In the Screencast I have Save As to a my folder and I then have complete control.

This is not a bug!

@g-andresen You are right I should have separated the issues. I will in the future. I managed to insert a limit that achieved the result of limiting the motion of the swingarm but in doing so I also found that there is much about animation that I need to learn. I see many of the joints have "degrees" of  motion with them that do not seem to function as limits but allow limits to be applied. Thank you for your guidance I will study that concept harder.

@jhackney1972  Thank you for your reply. However, when I open the sample I create an in memory version of the file. The "read only" property of a folder pertains to the persistence of a file not its editability that I can see. In the video I do a "Save As" and re-open the file but outside the video I also have the exact same results when I open the sample, "save as"  to my own folder, close the sample and reopen it from my own folder. It does nothing to change the behavior I noted earlier. I am not changing the drawing per se but only trying to look at an individual part of it which as a feature you should be able to accomplish even in a read only mode from a software perspective. The only thing I didn't quite understand from your screencast is when your say "turn them off", again I am a noob so this just might be my lack of knowledge but does that refer to turning off the visibility (i.e. hide/show) or is there something else I am missing? I must be missing something because if I (working with my copy) open the file select any other component besides the swingarm (rear triangle) and isolate it then unisolate it returns without turning on (showing) the bodies. If I isolate the swingarm and all the bodies show up, then I rehide them and save I get the results you do. Is that what you are saying? It just seems odd to me that only this component changes the state of the bodies on isolate. Is there a step to protecting against this I haven't yet seen that was missed in the sample? Again thank you for your help in understanding this.

Yes, this is what I am saying.  In the Screencast below, I point out there are other hidden bodies that are turned on when you Isolate and then Unisolate components in this model in it unsaved state.  By the way, you refer to the MODEL as a Drawing.  This is incorrect, 3D representations are called models, a drawing is the 2D representation of the model.
