Scaling problem of a Sphere or a Torus in Model Workspace

[Anonymous]

Hi, I noticed this problem a long time ago and it is still here after a few updates. I am using Fusion 360 everyday designing LifeStyle Products and Jewelry for our retail stores in SE Asia. I would say over 100 products already designed using Fusion 360 so I know. I am attaching five screen shots to show the problems.

1) if a sphere or a Torus is created in the "Model" workspace, trying to scale one of them, or both of them selected will not work.

Screen shot "1" and "2"

 2) Just to test it, a Box is created under "Model" and it could be scaled.

screen "3"

3) Only way to scale either a sphere or a torus under the "Model" workspace is to select other profiles with the "Sphere" or the "Torus".

Screen Shot "4"

4) I found a way to get around it, I can create both sphere and torus under the "Sculpt" workspace, then convert them to Brep. They could be scaled this way in the "Model" workspace. But there is one catch here. A sphere that was created in "Model" a center point could be constructed. But a sphere converted from "Sculpt" could not. I did not test this further, maybe I have to make the converted sphere into a solid first.

This happened to all my Apple computers. All my computers are quad core I7's purchased just to use Fusion 360. When I am using these computers, there are no other programs opened except "SugarSync". I always have another computer doing other things. OSX 10.8.4  Original Apple graphic cards. 4 gb memory.

Thanks for your attention!

PS Fusion 360 is a great program. I enjoy using this program more than others. These are small problems but I can get around it.

 I am in Hong Kong so there will be a time difference.

Hi Kingson,

When following your workflow, I note that I had to select the origin part for the scale feature to work. What are you selecting for "point"? It seems that a sphere or torus does not provide any geometry that can be used as the base point for the scale.

Hope this helps.

Thanks,

Hi Nathan, thanks for the fast response. I think I am used to changing the Tspline to Brep for it to work. But shouldn't it be easier as a feature just to be able to scale both profiles like a simple box? For example, 123D Design from your other department could scale a sphere or a torus without too much problem if i were not wrong.

Thanks anyway! I just check that as "accept as solution".

Hi Nathan,

I had already accepted your suggestion as "Accept as solution" .

Just to show you why scaling spheres are important to us, I had attached a screen shot here. On this ring, I used Create Radial Pattern of the "Model" Workspace to create a series of spheres on the ring band (say only 46mm circumference). Most of the time a single sphere needs to be scaled in the Model workspace to the correct dimension before I can move that to the band. After the spheres are installed, the whole ring can be scaled by activating the full subassembly without any problem:

Other features that I really like is the "Loft" with rail features. Attached please find a screen shot of part of the 18K gold structure that I constructed with two rails and a few circles on different planes (yes it is a little complicated now since I did have to offset a few planes, then project the circles for the connection points of the two rails. But once done it is very good.)

You can scale a sphere. You need to pick the point, it can be any work point or vertex.

Cool Ring! I am able to scale spheres and torus (bodies) in the Model workspace utilizing construction points as Kevin points out. In the below video, you'll see that I add two construction points. Then I can use these construction points to uniformly scale a torus or sphere as desired. Here's the video:

Let us know if this helps, or if I can clarify anything thanks!

Kind Regards,

Hi Nathan, thanks a million! That is a really good video. In fact I did construct the center point of the sphere but I missed out that the center point of the Torus could be used to scale it. That really clarifies the "Point Mode".

You had saved me lots of lost time. Sometimes it is just a matter of procedure. I think this video also helped a lot of users who might be facing the same problem but maybe they did not reach that far yet.

Now I am working on "Match" in the Sculpt workspace. I could match up a Tspline body with a sketched circle but for some reason I still could not "match" up two TSpline bodies as per the video. I will find the trick.. Well we are professional product designers we just have to find out the tricks and this Discussion Forum is a great help.

Great works guys!

Thanks for this and the other screencasts, Nate.

Next time, could you record in smaller resolution (run in window, scale it smaller) so that the shootage fits i.e. a Macbook Air screen. Also, it will make the downloads lighter and speedier for us.

Now I viewed in in full screen (essentially scaling the recording down after transfer).

Thanks.

Hi Thanks for the kudos

Asko,

Thanks for the feedack! I usually keep the window small to decrease the files size that I have to upload. Next time I will scale it down. 

Kind Regards,
