STL file import for sculpting edit?

[Anonymous]

i have built a model in another design program and exported as stl, now i import stl into fusion,can i edit it using the sculpting workspace?

[Anonymous]

to sketch on the leg you need to add a construstion plane , if you clicked on a flat spot it would use that . If there is a diffrent way i am sure someone will post 

[TrippyLighting]

That is incorrect. You can start a sketch on any planar surface of a solid model without having to add a construction plane.

but this is what you did on your video phil, you clicked on the floor and then you proceeded to the area of interest

I did click on the floor, but it doesn't really matter as far as I know what plane or flat surface you pick because your making a 3d sketch. 

In your video it shows faces and vertices highlighting, what I didn't see was your history bar. I did notice performance when highlighting a face or point on the mesh (Body 1) was very slow.

That particular mesh has issues because its not a water tight mesh. Try drawing a spline instead of a line.

i will try with aother model much cleaner and i will use netfabb to do autofix then i will use IM to make Quad and export as obj to then import to fusion and will see how it goes, as far as what you seen your right i dont like to use that history tab and i those things you seen was in the background on the floor not on the model like i said the only thing you can do is sketch on a small part on its shoulder as you seen in the video highlighted in yellow

How are you getting on with IM? 

Due to this thread I have down loaded it myself. 

I router rifle stocks and its in common for me to have some models of rifle stocks scanned and sent to me. 

All of my scans have been done using Faro V6. As it can capture 900k points a second. So the meshes come in heavy but very detailed. And they need to be! 

When i tryied using IM it made a horrible job of it. I lost a incredible amount of detail buy switching to quads. 

I agree strongly with other comments in this thread about bridging the gap between mesh and cad! 

Pits is sorely needed. Maybe it's a cad thing and Devs see scanning as satin! 

But fusion would seem to have a different outlook at it. 

BY THE WAY I also down loaded the mesh slicer plug in for F360. Can I just use the original stl for that? Or do I have to import it as a quad? 

I have tried it with a obj file converted from a stl but it would not let me select the mesh when I used the command!

im just going to speculate based on your info, high point are good yes but this IM is for mesh scanning not laser and this is cuz of the topology built of the points, like you said your faro provide high detail with lots of points and the IM is going to convert it to quads you will loose data your not compressing your removing by using IM, im not sure what processor your running but the more info to process the more processors you will need. regarding the mesh plug in i would just upload the onj file i never did stl or quad as i did not knew about IM but to be honest i dont use that plug in at all since i dont fully understand it tho it worked for me partly so i stopped using it and started using IM

Sorry for such a long delay Frank, my hard drive in my home computer crashed and I still don't have it all set back up. But it just occured to me do you have 3d sketches turned on? Because if you don't you will not be able to snap to the model geometry.

hey there Phil my pc ended up with issues so i had to post pone the whole sketch topic we were at back then, basically my pc has a slow connection and we have so much pictures and video links on this web pages that my internet connection is horrible and so im lost now, what was that work flow again ? so i bring in a solid model right for instance i have this skeleton and just for kicks i want to make some external plates to wrap around the bones now what type of conversion am i supposed to do ? i have this model but im not being allow to convert or sketch 

so i try to convert came up with this but even this is not letting me sketch on it

[Anonymous]

ok so i did a quick 3d scan of myself and came out kinda ugly lol but i  was in a hurry i wanted to see if i can use IM to make a 3d scan into a quad mesh and as you can see it kinda work and now i have other questions 

ok so my question is how do i make the sketch stick to the surface of the model ? i start ok i guess but as soon as i hit a curve is like im sketching on some other part of the model, notice how i started around my ear and i started to go to my eye socket and now somehow i ended up in the back of my head also my chest, i started on my top and as i try to get that rib area i again ended up on my back.

and one last thing, i wanted to bool out my body so that my body contour take cut shape to the model i kept but at this body now its too boxy and therefor the cut bool job will result not good, is there a way i can cut the the new model so that it can keep that shape where it seats on my face or chest?

Can you post the model for the leg bone?

I will do a sample video for you but it will be a few days as my house is in disarray I got new furniture and can't even get to my computer right now until I get all the old furniture out, sorry.

[Anonymous]

yes i will upload momentarily, and i appreciate your time Phil

[Anonymous]

here you go i sent 2 types of the same model, this are the only convertions i was allowed todo in Fusion.

show me how is it the we follow along whil sketching specially around curves/contours and the workflow for your convertion process, this will be for printing so lets work with model that i can buildother components on top of after sketching and able to print Phil.

what you see in this bottom picture is what im looking to do.

Ok as promised I'm going to outline my workflow for what you want to do.

First I took your model and opened it in Topogun and retopologized the model so I have all quad polygons. This step took about 10 min.

Now you can use whatever app you want for this step (Blender, Zbrush etc.), I just prefer Topgun.

Here is the results:

As you can see I ended up with a nice quad mesh that weighed in at 1270 polygons, well under the 10,000 polygon limit. Then I saved the model as an .obj and uploaded it in Fusion.

Working on step 2.

Here is the video for working with imported Model: Make sure 3d sketching is checked!

Working on part 3.

it does look lovely !

@Anonymous

Here is the obj file if you want to give it a shot.

As I have said in other threads the real power of Fusion 360 is with hybrid modeling. Given the fact that you have T-Splines, Surfaces and Solids that you can work with, this makes Fusion very powerful. Using all environments together and interchangeably is the key to that power. So as long as you follow some key rules it's possible to model anything.

Part 3:

Ok this should be enough info to get you well on your way to making what you want. If you need more help let me know.

Changing an .obj file into a T-Spline.

[Anonymous]

thank you once again Phil, this should be enough i just need to find a good cheap/free tool that can convert to quads

[PhilProcarioJr]

@Anonymous

Any chance you could give me the entire skeleton in .obj format? I would like to try some stuff.
