Learning move, import, cut, orientation and positioning with snap.... how to

[Fonzis]

Good day
I am an Acad hobby user looking to become perfect continuity on lofted surfaces created from spline constructions, my preferred creation method.
The forms are organic combined with mechanical parts.

I have give it a try in Inventor but Fusion definitively convinced me better. Less complicated and the orientation between planes is  more userfriendly as in inventor for me.

In Acad i use to construct things taking orientation direct from the splines that i form related to the positioning that i do in the 3 d environement. Orientating i do by typing or activating the snap commands  that i need, in free orbit cam.
At the moment i am learning and starting take confidence with fusion.

I have try to import as igs step and sat, it seams to not import 2d at all.
I am here to ask for 2 things, first of all i am tryng to import splines from acad.dwg/step/igs to prevent that i must construct all again in fusion.
The first question is, what filetype have i to import in fusion to have also the splines if it is possible? (I need them to reconstruct it by using T splines). Or what method do you suggest if i already have the lofted surfaces from acad.
I was thinking to loft it in acad even if i not have perfect continuity, cut the surfaces following the splines, after cut it take the edges to reconstruct them with same shape and intersection points.
My other question is, how to import sketches or creations made as 2d in acad (mechanical) to use them as reference in the sketch that i need to position at his place and need to be in relation to the loft guides that i wanna create?

First pic is an older grip, stitched to become it solid.

The other one is the actual one i am making, taller, smaller, no socket and adapted to another trigger mechanism.

Any kind of suggestions are welcome.

PS: i am looking for a good snap and move tutorial in 2d and 3d environement, if anyone can link me to a good one that allows me to understand how move and position better like i can do easy in acad i would be happy. Thank you in advance.

Impossible to finish it. He does not accept fill hole command in freeform it always give error, and create edges is pratically impossible.
Beside performance problems with fusion now also function problems.
I give it up

Thank you anyway for your help and time.

Hi @Fonzis,

I will try to use the 20k element stl and see if I can do something and keep you updated.

Could you also share a public link of the original AutoCAD design? I might want to use it as a reference surface.

Thanks,

[Fonzis]

Ok Mike, thank you very much.

Pass same as before

[Mike.Grau]

Hi @Fonzis,

I have worked with your iges file and I was able bring down the number of elements to 10400, so still not the target.

Could you share your dwg again? I was not able dowload the file since it says that I do not have permission 😉

I´d like to see if we might get better results if we play around with the AutoCAD output options.

Thanks,

[Fonzis]

Me also i was not allowed 😄 seams corrupted or broken after fusion import even if no changes was made.

I made new upload without be translated in fusion before. All is ok now.

pass is same
Thank you again

[Fonzis]

Hi mike, did you have any luck? Let me know when you have time.

[Mike.Grau]

Hi @Fonzis,

Yes, I had luck by creating a useful T-Spline model. I have actually used the *.dwg.

To Do This, you can follow these steps:

1. Close the design it in the patch environment
2. "Unstich" and "Stich" all faces to have one surface
3. Use "Boundary Fill" to create a body
4. Use this new body in the "Sculpt" environment to convert each face into a T-Spline
5. Merge the edges of your T-Spline faces

You may want to play with the "width spacing" and "length spacing" when you convert into T-Spline.

Here is a screen shot of the feature you would like to use.

 

Here is the link to your design. Please, feel free to use it and modify it. 

It is your initial password. http://a360.co/29lvVpc

I hope this file helps, just keep me updated if you could use it.

Thanks,

[Fonzis]

Hi mike, thank you very much, i have try to download it, but password is not correct.

I inform you that  i already tried to convert it as single surface like you, the problem that i encounter when i merge edges is that i lose match edge command and the regularity between the other surface becomes broken at same time. As soon i play around, because i cannot use any references in freeform, i lose continuity elsewhere so i was pretty sure this is the wrong method.
This problem with losing match edge is the main reason why i didnt repair the bad gone lofts with freeform from single surfaces and why i am tryng to obtain a single freform from a solid respectively the mesh we made.

I gonna try again for sure with your file as soon you give me correct pass, perhaps it has to do with the boundary  as you describe.

I wait for you and thanks again

[Fonzis]

http://a360.co/29jj87Z pass as usual

This is the best result i achieved as mesh, just to show you the difference to the 20 k version you gave me where the shape is pratically lost compared to this one.
The problem is and remains the union of the surfaces and them continuity, in freeform using my own dwg i was not able to become positive results.

[Mike.Grau]

Hi @Fonzis,

Thank you. I´m not giving up. I have tried to use the "Intersect Mesh" app to cut the profile of the mesh body.

https://apps.autodesk.com/FUSION/en/Detail/Index?id=5742637258089280352&appLang=en&os=Win64

From the profile you could create new splines on it and use them to create patches.

Once you have closed the model with patches, you can convert it into a T-Spline Body.

http://a360.co/29nws88

Another approach is to cut the original model and re-create patches from there.

http://a360.co/29nxaCu

It takes time to create a clean model without any intersections. You can try it as well.

Let me know if you found another way.

Thanks,

[Fonzis]

hi mike, me neither, i am combatting to make stitching and i think i have a solid now.

I click your links, but nothing happens after put password, he freeze and no enter, so must be wrong password.
I cant download or access your links with the pass from private message.

Let me know
Regards

[Fonzis]

thank you for the invitation. I downloaded it, but i was not able to do this operation like you described. Fusion crash all time when i try use this add in.

[Mike.Grau]

Hi @Fonzis, 

Thanks for the update.

Could you might check your RAM during the operation?

Have you may submitted a CER?

Thanks,

[Fonzis]

Hi Mike

Ram never went over 15% usage cpu max 5%. Sometime he use 3000 4000 ram, record use is in mesh conversion 8000 - 9000 . Feel like working on a PC from the 90s, this is total frustrating and the problem is surely not the hardware.
I am tryng since hours, always same, i go in sketch tryng make those intersections and he crashed many many times, just before had a bit luck, it has run stable for 1 try. He didnt crash but had 3 or 4 times unexpected error before give me at least 1 cut line per plane.
I killed fusion process and restarted, then he accepted mesh intersection but only on origin planes, dunno how use it correctly and make kinda mask net, i do not find any informations.

[Mike.Grau]

Hi @Fonzis,

Thanks, yes I know it can be frustrationg. I haven´t had issues with intersect so far.

Could you may send your *.nfo file? I could have a look into it. Here is the link.

Have you tried to use "Split Body" "Split Faces" with the Patch file?

Thanks,

[Fonzis]

Hi @Mike.Grau

Split body and faces with patch file.... to take lines from cut edges? Can do this without tool intersect mesh add in normally, but no sense if lines come from non adjacent surfaces that are corrupted, no?

about the files in a360, found 2 of them, one an old 20k mesh with lost shape, other a yellow one with a sketch in it and closed behind.
I used your yellow one to make all possible trys that you suggested.

First in fform but without references or good sketch it has been impossible become results like from dwg. and make a correct union symmetric and without twists.
Intersect mesh add in is "frankensteinware", doesnt work correctly, he hates overall imported mesh. From your file coming mesh sometime he has appreciate he just gave failure, mine he crash fusion constantly.

Here some other pics of an issue that i try to bring away since days and it also dont works.
Thats where i am at trying become better results.

I am going out from original dwg even if splines are corrupted. Seams to be the only sensefull way to avoid power problems.

Near mouse you can see how right side is perfect and left side has kinda deformation on same point. Nearly impossible to fix this. Is the first union that has a nearly acceptable shape, if only this deformation would not be

Use make uniform function is very very limited. Even if on the top i use symmetry and try to adjust edges/int.lines to connect properly and with same quads ammounts, after i do merge edge weld vertices try adjust the rest (before or later), there are always twists.
Simmetry gets lost  elsewhere and i am never in the parameters of sketches.

I started combat with other side today

I go on with Ffrom to see how far i come, i believe that this is the only way without alternatives if i dont wanna remake original splines in fusion itself.
Go out from meshes or something else that cant be imported without corruption is only waste of time in computing and crashes that made my stomach become a poison industry.
2 Months combatting with mesh and no result, i would say thats it.

The deformations on top of freeform body and behold them simmetry where it should, are my actual problems. If i will be able to adjust top side the rest will be possible to.

You think this little deformation can be removed in fform and made simmetryc? i have try for days make a good union, but was not able to make it perfect without issues like this of zebra and "no edge" pic.

Thanks to you Mike

[Fonzis]

Since this morning impossible go on with freeform construction.

Each click takes 20 to 30 seconds, simply create new faces on 4 points is impossible without waiting. Same problem by selecting freeform faces and tryng to subdivide them. No response and all time it crashes.
What can i do to can work properly and without extreme performance problems like is happening already for the third time?e

[Fonzis]

with the last crash i also lost the file, it says open recoveryfile  was not possible , file corrupt.

8 hours work on freeform construction lost cause a fu..ng crash!!!!!

[Phil.E]

@Fonzis

Sorry to hear of your loss. Can you locate and post the recovery file? We need to analyze it to prevent this kind of corruption in the future.

Also, can you post the model again if you get it to the most recent state in this post? I checked on your CER reports and could only find 3 from this week, but it sounds like you may have crashed more times. The crashes are related to your model, and happened in the T-Splines code, so getting the model will help us make Fusion more stable. Thanks for your help.

Regards,

Phil

[Fonzis]

Good evening @Phil.E
Thank you for your attention

It is already the third file that is lost as corrupt. The other 2 was locally saved before fortunately. I never liked this saving system in fusion, now i surely know why .
The crashes happen very often and it is the anger that makes me close the send report window. Else you would have plenty of them. Today i had minimal 12 to 15 crashes. I am forced to make little steps a time instead can work normally, it is a really stupid situation.

Just to make you know, no matter what version of file or what format i am working on, if offline or online. The performance problems i have them surely since 2 updates ago.
I followed instructions and setted dpi check off and dX11 always on instead auto, helps nothing. Changed drivers, check hardware, bench tests and all possible stuff, fusion is kinda plombed on our pc.
2 Days ago lets say i was working, i was making unions and adjusting the fform stuff to the original dwg surfaces, lot curves complex job but possible, the computing times was ok to work on but to slow, since this morning each click an eternity, crashes, bugs in surfaces, work has become impossible. No stranger processes in task manager, total clean win 10 pro sys. running all other programs like the wind, but only fusion no way to make it work like it should.
The lost file costed a lot of worktime, it was 3 complex unions that now will be hard reconstruct as they was. Yes i am really pissed off, because i know the computing time that awaits me again and all the cells that i have to split, combine, slide adjust pppfffffff...

3 projects like this and the enterprise is ruined because the coffee and tobacco consumption in computing breaks...add to it the lost of files  saved by hand,  that now must be reconstruct, enterprise goes bankrott before go in production lol

You can have my actual file to check it yes, but the crashed one is lost, was the nearly finished one. tomorrow i send you
I need fusion with performance... can we do something for performance?
