Scale in Sculpt

[LMD001]

Hello Fusion 360 Team,

Sculpt - Form Edit - Scale.

Entering a scale < 1 say 0.85, causes the form to disappear and Fusion 360 stops responding.

Entering a value that starts with 0 seems to trigger this.

Many thanks and kindest regards,

Ludo

Hi Ludo,

Looks strange. Could you please share your model with us? We will check it to know more details.

Thanks for reporting this issue.

Hello Sdpatil

It is a simple cylinder.

It occurs when you change the value in the HUD from let's say 1 to 1,1 and to 0,75 again, typing the 0 causes this.

Screencast: https://screencast.autodesk.com/main/details/07998a4b-4c05-4913-9c98-43277ddf5c41

I have sent 2 error reports: 

CER_108596382  CER_108597181

Hope this is of any help.

Many thanks for your reply and kindest regards,

Ludo

Thanks a lot Ludo for quickly capturing the video and letting us know the steps!

Yes, we can reproduce it for the same workflow. We have logged defect for the same and are looking into it.

Thanks Ludo. It should not crash, we are debugging it.

However, let me try to explain some things beyond the crash that might be confusing. The speed with which I type in the mini dialog box matters. If I type "0.85" slowly it takes "0", then "0.8" and then "0.85" as inputs and does the edits. If I type fairly quickly "0.85" it takes "0.85" for editing. This is for all the commands but I think here it gets confusing because of "0" scale.

About "0" scaling. If I select the T-Spline body (like in your case) and scale it with "0" it collapses to nothing. Further editing of "0.8" doesn't work. There are some cases when I would want to scale some entities with "0".

Please refer to this example- https://screencast.autodesk.com/main/details/480903c9-3205-41fb-be66-5a4eddcac075

I want to cap the cylinder in a specific way. Fill Hole caps it other ways.

Also please refer to Taylor's video

https://www.youtube.com/watch?v=4JRHsyIWgs0&list=PLmA_xUT-8UlLB0sfkzvbp8MtwCo4Nxild&index=19

where he scales a loop of edges to "0" to flatten them. Perhaps that could be done by Flatten command as well.

Hope this helps.

And we will fix the crash.

Thanks,

Hello Anand

Moments ago I tried typing real slow, but on my system Fusion 360 stops responding at the "0". Error report:

CER_108603225

I did not think scaling to "0" would make any sense, in my case just making the cylinder a percentage smaller would make sense, scaling to "0" not really.

I see what you mean, that scaling to "0" does make sense in some cases, probably only when using edges and not the whole body.

Thanks for your reply and the useful links.

Best regards,

Ludo

We fully understand the crash and have a fix!

Regarding sacling to 0 for whole T-Spline body - we will take it up for more discussion internally.

Thanks,

Forgot to mention this yesterday - the most easier workaround to avoid "0" scaling and crash is to key in leading with a decimal but not the zero, that is something like ".85"

Hello Anand,

Thanks for the workaround!
