from multi-superficial stp apart

[Mario101]

Hello.
we often use parts sent by manufacturers via stp. as long as they are simple pieces I do not lose too much time in operations, amount and save as part not thinking too much about loading problems or slowness that can cause. but now man sent us all a truck and the cabin consists of many small triangles.

through currency performance I noticed that the chassis takes a lot of time to be loaded, perhaps because it has so many holes repeated. on my return from the holiday, I'm already thinking of recreating the whole frame through extrusions (it's not too difficult, it's a u beam with lots of holes, I can do it in a short time). I will probably leave the original stp transverses. This is the solution that I would like to follow to solve the problem and see improvements (now the truck is weighing 100 mega).

other problem instead of I haven't had the chance to deal with yet is the cabin. all those triangles in the table are annoying, one cannot make such a table. plus more lines there are and more my drw will weigh and it will be difficult to manage (the machines are not very powerful). I wanted to try to do something like this:

This has only "simple" surfaces, in the table I would have no problem. a colleague of mine tried to process files with blenders but then they were invisible in the table (visible in 3d). so I would have thought of taking maximum contours of this cabin and working with extrusions and cuts to get a maximum encumbrance of the cabin (which is more than acceptable as a result). Has anyone ever done that? Would he have any plans? Unfortunately, I can't prove practically I have to base everything on theoretical results but I would like to get to the reopening with a definitive solution.

Thank you.

if it is full of triangles probably is a step derived from a stl, otherwise it does not explain.
the beam full of holes should be analyzed well because if it is heavy now that it has no function that requires regeneration, do it from scratch with functions will hardly improve the situation.
Sometimes you can improve the situation by importing files with the activated 3dinterconnect, which allows for greater opening speed, then saving it as part (if it is a set) or inserting it into a set (if it is a part) and saving it as part.
Unfortunately, the optimal solution does not exist and we must go for attempts; also accurately analyze the file, removing bodies and surfaces (not deleting with the appropriate function, but directly from the feature manager in a definitive way) and studying performance statistics to understand sensitive areas and act precisely.
then the system options setting should be optimized if necessary.
the file you're elaboirando is the one in the grabcad link?

It could be, unfortunately man sent us this and they have nothing else to send us (we requested a freshman and sent us another without pto). This car will be the first thing I'm going to dedicate to return, I hope to find a method that allows me to fix it. now is the most expensive part. Maybe by making a single hole, using linear repetitions, I could get something more agile. I don't know the 3dinterconnect, now I try to see how to use it, thanks for the suggestion.

no, the file is that of official man, I would like to get something like that of grabcad, where the cab of the truck is made of simple faces, I do not need to make rendering but only simple constructions to read. having a thousand triangles on a sheet certainly does not help, I cannot put myself to hide a thousand lines on the sheet every time (we do many different sheets with the same truck to have the installation of all parts).

Surely you have to do some repetition functions because thinking about making dozens of sketch holes is unthinkable.

No, the file is official man's, I'd like to get something like grabcad,

it is difficult to give suggestions on the only description of the file and without even images. ideal would have the original file, of course if possible. or the link if downloaded from a commercial site.

I would like to point out that all this to a common user does not say anything as it does not have your knowledge of the project you are working on.

Unfortunately it is not downloaded from a commercial site but they gave us access to these stp indicating the freshman and a number of other information. I hope on my return to be able to make a screenshot of the polygonal cab that we have and of a result that I would get (some in the past in the office had done this job on a mercedes but there is no more to ask him some information, from what I saw inside the part, there are so many extrusions starting from sketches). I hope I can add more information at the end of August.

blender has tools for retopology , technique with manual tools that allow to "wrap" the many triangles in larger surfaces , but also solidworks has tools , also manuals , for reverse of imported mesh , perhaps you should deepen the knowledge of these topics

 

[Mario101]

but also solidworks has for some years instruments, including manuals, for the reverse of imported mesh, perhaps you should learn more about these topics

I didn't know sw had these tools. I start searching for instruments, can I ask you what tools do you talk about? so I can compare the methods that I will go to deepen with yours. Thank you.

 

[Mario101]

Good evening, I came back to work today and finally can post a photo of my problem. This is the man that makes me trouble.
When you put it on the table, you see all the triangles. today I tried the silhouette tool to create the sketch from which to create the extrusion but I did not have good results (the silhouette was not minimally close to the original model). the front windscreen is the only one that you could easily realize through surfaces because it is separated from everything, I isolated it and through surfaces you can do.

How could I proceed to simplify?

 

[MassiVonWeizen]

If you can't import it better you have to use the existing geometry to remodel it completely.
Maybe you can improve it with the eliminates face function, but you have to go to attempts.
of course they are advice given to feeling because you have no idea how the model is made (all surfaces? solid mixture and surfaces? multibody or unique body? )

 

[Mario101]

I tried with and without 3dinterconnection, but it did not serve... eliminates face does not work (or I don't know how to use)... remodeling it completely is a piece that takes a long time that unfortunately we don't have in the office... It is mixed surfaces and solid bodies, it is not all in a body but they are different bodies (porter, windshield, upper cabin, lower cabin, last separate step)... they certainly did not facilitate us... to remodel it completely you want to start with lines and splines to find the external sketch?

 

[MassiVonWeizen]

theoretically the ideal would be through surfaces using existing geometry.
difficult to say with the image alone; in these cases we must go to attempts to find the best solution.
Then it depends also on what you want to get, and you didn't say.
Do you have to make a detail design with several odds and views? you have to arm yourself with patience and rebuild it completely in an accurate and lean way;
Do you have to make a handbook design with notes and a couple of odds? accuracy is less accurate and maybe you can recover something from the existing one by combining surfaces, deleting faces, baring somehow;
Do you need to insert it as an accessory in a top design like a parking lot? accuracy is minimal and you have to "only" engage in eliminating triangles with extrusions, cuts and radiances.

otherwise continue to break the bales to those who gave you the step clarifying that you cannot use it and if you have also paid that they give you usable.

 

[Mario101]

I'm gonna do a lot of other tests today and see where I'm coming. thank you so much for the advice.. .

 

[Mario101]

I did the tests and managed to eliminate the 900000 faces of the present car. it was simple (a sweep of a beam to u along a line, I did not report the holes because we practically did not have data to do so and we can not measure those present in reality).

But I would like to do the same thing on the cabin. I would like to model it for surfaces or solids but I have never faced the problem before. I would therefore ask you if there are courses also on udemy or specific texts with exercises to take your hand at home and be able to replicate the result at work.
