"Mesh is not Oriented"

[william_twyford]

Just curious how to address this error. Is there a new way to set the orientation and save it directly within the mesh?

I often use scanned models to get a general feeling how much space and what constraints I have to work with and am comfortable scaling and orientating meshes (using a ball joint).  As I don't need to convert these to solids, I don't care if they are closed / have positive volume.

I used to work on Scan to BIM projects before, and this issue was always a pain to deal with, as I needed to get the right coordinates and rotation of the mesh from Recap and then move my mesh to the right position and orientation. Although I could position the mesh manually to be very very close to the right position, the orientation was a pain to deal with as setting it manually was causing inaccuracies. This issue arises from transfering geometries between softwares, and it's very common, but there is no clear consistant way to avoid it.

Can you zip and Attach the original file here?

(In Window OS right click on file and select Send to Compressed (zipped) Folder.)

Thanks for your interest and perhaps to save some of your time, any of Fusion's mesh repair options will clear the errors.

I guess I should try and clarify my question.

If Fusion has an error that the mesh is not oriented, does it have (or plan to have) the tools to orient a mesh (to the users liking) and bake the new orientation directly into the mesh file; rather than the current workaround, scale the mesh and define planes within a component and joint the component in the orientation required.

Again, I'm just curious. Irrespective of the tools used, the same work has to be done, so there probably isn't a workflow improvement.

Thanks for your time.

I think there is a much easier way to, but it will be Monday till I have a chance to record a video.

Thanks looking forward to seeing it.

But just in so we don't cross wires, my workflow is:

1) Clean up mesh in Blender (optional),

2) Open mesh in fusion and optionally click "Repair",

3) Create 3 pt plane across best reference surface (in this case the bolt pattern),

4) Sketch Line between two measurable features, measure real world distance and scale mesh accordingly,

5) New Plane and Sketch (if you can't use the old ones due to them not being compatible with the desired orientation and location), create a square or rectangular profile aligned with the desired orientation and origin and extrude a solid. I place the solid so that one of the grips will be the new origin.

6) Join solid and mesh as rigid group or As-Built Joint,  save as "scaled version" and close.

7) New Drawing, drag and drop scaled version in as new component, cancel out of move copy dialogue box. Joint the "Component Solid" to the "New Drawing Origin". Align Solid faces to Coordinate Planes and close joint dialogue.

Note: in the second example, I imported the mesh and solid as a derive in it's own component.

Hope the extra info helps.

Thanks

If I understand this sentence correctly "bake the new orientation directly into the mesh file", then yes there is a way to bake an orientation inside the mesh.
In my previous reply, I said that importing the mesh into Fusion 360 won't give you the correct orientation, but in your reply you're saying you want to bake new orientation into the mesh after importing it into Fusion 360, and that can be done.
The way to do it is through the file menu > export. It's sound so simple at first, but it has a huge advantage, as if you export the mesh by right clicking the mesh body (broweser>bodies>mesh body), you won't bake the new orientation inside the mesh, also if you create a new component with the mesh body inside of it, then export the component as a mesh by right clicking it from the browser, it won't get the new orientation baked into it, so always keep this in mind, in order to bake new orientations inside a geometry when exporting it, always export from the file menu.

A quick plus tip, if you don't want to export the rest of the project, just jide the rest of bodies by isolating the mesh you want to export so that it's the only thing visible when exporting.

I assume you are experienced with 

scale

external components

Joints

Edit:  I hadn't looked at your example of where your mounting plate was located - but I think you get the idea from my example.

I was expecting more questions as I didn't take the process through actual use case as used in assembly with Joints.
