My models exploded

Anonymous
Not applicable

I have had so much troubles with Fusion 360 lately. 

 

Insert into current design is causing terrible problems.

 

When I update the inserted model everything explode on the model it was inserted into. The same thing if I delete it.

 

Then I just hide it, save the model to be inserted on a different name so that it can be inserted again, and it does not insert correctly. the parts do not stay on their places and some parts are missing.

 

It tries to compute heavily and long and always with unwanted results. What is going on

 

I am using Latest MacOS on 15" 2017 MacPro.

"who hasn't even begun to understand how parametric modeling works from using Fusion 360 is really uncalled for!"

 

That is right, I do not even know what that means, still I have been using Fusion 360 for 3 years now. With Fusion 360 I can do what I need, the problem just is it is not reliable, it breaks down and destroys models. This is not the first one.

 

Every update brings new problems. So much time wasted just trying to get around the problems.

 

You are on really bad denial, it is not the Fusion 360 that does not work, it is the enduser that uses it wrong. I admit, I certainly do not use it as you intended. I have no interest on 3D modelling, other than get my designs done.

 

Is it really that unreasonable request to be able to delete timeline when so wanted without saving as STEP. And to be able to remove Sketches without affecting what has already been modelled.

"The other "distraction" you describe is called "through selection" and is usually very helpful. However, that can be turned off in the selection filters. That, by the way, is not a new feature. Fusion 360 has functioned this way for years!"

 

Where exactly is that? I want to select only visible faces and edges, I can not imagine how anything else would be useful and certainly do not like updates change these settings.

If you don't know what parametric modeling means and obviously don't understand how it works then it matters not how long you've used it. Apparently you've leaned little and blame your ineptitude on the software.

I've used parametric 3D CAD since 1998 when I started using SolidWorks.

I started using CAD and 3D modeling software in college more than 3 decades ago. I've designed complex manufacturing machinery and a number of end products.

 

As an Autodesk Expert Elite I am a customer just as you are, albeit vastly more experienced. I've used Fusion 360 since November 2014 and have a pretty good idea of what can be done with it and what can't be done with it. As such I am not in denial. I am just more educated than you are!

As I've explained in my last post, you cannot design in a CAD software without modeling in 3D.

I did not "request" for you to turn off the timeline. I suggested it only because in order to fully understand it you need to understand the basics of parametric modeling. You already stated that you don't. It also seems clear to me that you don't want to spend the needed time to familiarize yourself with the documentation nd tutorials.

That is the reason why I suggested you try modeling without the timeline enabled.

 

I would never export to STEP and then continue to model. That's just stupid!

I find Fusion very reliable but I use it the way it is intended to be used. The problem with deleting sketches is that the program needs sketches to work and they are all kept track of and one feature is built upon the previous features so deleting them is like going back in time and killing your father before you were born.

 

It's fine if you want to work that way, just realize that others do not have your issues because you are using the program in a way that it was not intended. 

 

Maybe Blender would be a better program to use for your way of working.

Thanks, that fixed it.

Well after some testing, it is not overly selecting the linked file behind other objects, but it is still selecting trough at least with some tools??

I do not delete sketches, but only because they can not be deleted. I do not though see any reason why deleting them would be any problem. Occasionally I have to delete the time line converting to STEP and back and that deletes also sketches, no problems.

 

The problem is 100 + unused sketches on side bar is plenty of scrolling.

"I did not "request" for you to turn off the timeline."

It has very much unwanted side effect that I do not understand what it is, it seems the timeline is not turned off. It is just moved on the side of the modelling area (side bar) what is this.

 

https://vimeo.com/431487322

 

This is totally unusable option. it very fast grows huge on the side bar and makes working impossible. it is not possible to collapse those.

 

That video BTW shows one other big irritation. Sketching automatically rotates the model. Can that be turned off?

So why don't you read through this documentation explaining the difference between bodies and components and then familiarize yourself with Fusion 360 R.U.L.E.#1?

 

Maybe it will dawn on you how to use the tool properly 😉

Yep. That I find irritating as well.

YOu might also turn off the two auto projection features. I personally don't want anything projected into my sketches automatically. I prefer to have full control ove what is in my sketches.

A little more work. A lot less hassle down the line.

What tool has this kind of limitations??

 

  • Avoid moving bodies around a lot using Move (physical location) or Cut/Paste (component ownership in browser). Try to design them in place by sketching in place in Active components.
  • Avoid unnecessary relationships between bodies that reside in different components, such as split body references. Instead use construction planes defined by the origin if possible.

I constantly do those things.

Thanks, that was useful.

 

I had to Google where the preferences are. Under the user name, not very traditional place.

@TrippyLighting  do you think it's possible there are un-captured positions here?

I can't think of any cases where you would need to save and insert a design with uncaptured positions. But to this day you can save a design in this state.

That is good to know, I did not know there is these buttons, but was starting sketch just to capture the positions 🙂

 

But anyway, I do not understand why not capture the position always, at least as default, and saving of course.

 

What is the use case where you do not want to capture position? It is easy to forget to capture the positions, when it is not default action.

 

That has been a problem sinse some update this spring. I think that button will solve that, but the current problem I started this post about seems to be deeper. Anyway it is now solved by saving as STEP and reopening and renaming bodies...

No, that really solves nothing. As you also ignore the links to the documentation I have provided in previous posts my help in this thread has come to an end. If you refuse to learn then my work is done!

It solved the problem for me, to be able to proceed and now the model is ready for 3D printing, maybe few aluminium parts will be send for manufacturing, they are simple parts and will be send as STEP file anyway so that will be fine. This is the second proof of concept of 360 video drone. Below is the first one, on that the frame was completely hand build

 

Screenshot 2020-06-23 at 8.21.49.jpg

 

 

 

There was some serious problems with that, but many things learned

 

https://vimeo.com/426557451

 

It is very unlikely that any of the parts on current model will go to production, but some ideas and experiences might end to future product. the 3D modelling I do is just mandatory step to build the proof of concept, that is where my focus is and it bugs me that the 3D modelling tool takes so much attention.

 

I do not quite understand what the Fusion 360 is, who are its intended customers. What I hear professional 3D modellers do not use it. There would be plenty of customers that need some tool for 3D printing and basic design needs like I, but the Fusion 360 clearly is not for them, it has too complex concepts.

 

It works fine as very basic tool as I use it, until the model breaks up because I used it "Wrong" I just used basic tools for 3D modelling, so I do not think it is acceptable that the model just breaks because the customer was using the tool "Wrong". (Would you be fine if MS Office would destroy your work because you used too much copy/paste, and what is "Wrong" anyway in using copy/paste.)

 

The solution for me seems to be saving occasionally as STEP to clean the crap from the models, that is the unused sketches and timeline and maybe something else that is under the hood. Maybe I just completely should start using STEP as saving format and manage the files locally, a bit inconvenient with Fusion 360 as it is now, but really the functionality I would prefer, to have the files locally.

 

So I do not really know for who the Fusion 360 is for. I am starting to think it is inexpensive or free alternative for students, to teach them Autodesk 3D modelling concept, with main purpose to get them using Autodesk products in future, so sad, it could be ok product, now it feels like a proof of concept.

 

Oh well, there was just a new update, lets see what new problems it brings.

While I congratulate you on successfully completing physical prototypes, my recommendation would be to use another software. Maybe TinkerCAD or Sketchup will do a better job satisfying your requirements.

 

I would actively discourage you from continuing to post to this forum. You complain, but when users with vastly more experience across try to help and guide you, you completely ignore their advice and continue to complain about the software. That is not only unreasonable, it is unconscionable!

I think it is very reasonable request I have, that the tool does not destroy the model. It is no excuse that I used too much Move, Copy/Paste, Extrude, and did not use Joints and had too many Bodies. The tool should not fail like it has failed now me couple of times.

 

Further more, there is option to disable the timeline, but it does not seem to work, or at least has side effects that I do not understand and make it not usable option for me.

 

I think it is also very reasonable request to have function that cleans the history when so wanted, like saving to STEP and loading back does, but without the side effects, loosing features that I do not want to loose. Also to me it seems very reasonable that there would be option to remove single or multiple sketches when so wanted, without that affecting what was done before. That also work via the STEP procedure, but it removes all Sketch, not always wanted effect.

 

I have no intention to stop using Fusion 360. For what I do it is mostly ok tool, as I use it, but it is not acceptable that it has this kind of major flaws, destroying the model. Luckily I have always been able to safe them, but it has been a lot of work.

 

Also I have no intention to stop posting at the forum.

 

BTW, after latest update, the selection tool seems to work now as expected, at least for the see trough feature disactivated does not select items behind visible parts and inserted models are not dominant like they where before.

Fusion has minor flaws, not major flaws. You are the one with major flaws because you won't listen. 99 percent of the users out there will never have the problems that you have because they understand how the system works. 

 

There was a older post by someone smarter than me who explained what was going on under the hood of the program and basically Fusion names and keeps track of the location in space of every sketch line, surface and edge so removing one line that was referenced one one face can have a detrimental effect if deleted.

 

One thing that you can do with the history turned on is to convert a feature to a direct modeling feature "DM Feature" by right clicking on the feature in the time line which removes history for that feature. 

Here is an explanation. https://help.autodesk.com/view/fusion360/ENU/?caas=caas/discussion/t5/Fusion-360-Design-Validate-Doc...
