autocad 2021 - news

  • Thread starter Thread starter PlannerRoad
  • Start date Start date
He went out on March 25th.
I think there is (in summary):
  • various incremental performance improvements, the interface
  • integration with google drive (yes it was available with other cloud storage, type dropbox, onedrive and (from time) box
  • comparison between different versions of the dwg and xrif before updating (useful steps, to see how they have been implemented for cases of heavier changes)
videos (in English) on youtube show something of these features:

the only thing they have actually improved is the comparison between files... for the rest they could skip the version!
optimized the program to use 100% computer performance to speed up display (especially in 3d) would be better!

absolutely agree. I often have to transfer the design to 3dsmax because autocad crashes when the file exceeds a certain weight.
decided to make a cad that requires a expensive video card, while 3ds uses a video memory that allows you to manage views in an acceptablely fluid way even if the file is hundreds of mega. and without spending a boat of money on the video card.

for charity, perhaps it will be a limit of autocad for the way it is planned, written, thought... but because it is not for nothing free and it is in use to many professionals I would expect that they would spend on something more in terms of the above mentioned.
sometimes you see the program planned for minutes and a good pc (disco, cpu, video card, network) that is constantly at 10%, or more of them.
with heavy files or export of files from other programs (even relatively light) even in 2d has some "holes" of a few seconds during the execution of some command or a simple pan, which is quite annoying to work there as well as a limit for our productivity.

and it is not from this latest version that I know these problems, I think already from autocad 2018.

because it is a video management that is very poor. I think it is a kind of memory that is reserved precisely to ensure video fluidity when you have several objects. While many programs have this video memory (3dsmax there is it and works egregiously) autocad relies on the video card for managing those calculations.

try to fill with tiles a roof, even if built in low poly, with only one surface for each tile. at some point, if the mouse cursor dwells on the tiles ... it freezes and remains for minutes before getting rid. and the processor does not work during these moments.
can be tile like any other objects.
that is why autocad has the possibility to manage video cards. who does not have the video card that autocad claims (usually expensive) is forced to a series of inconveniences that waste time
and it is not from this latest version that I know these problems, I think already from autocad 2018.
always... I had to be punished by the retinatura already with the autocad 10 (not 2010, just version 10) but at that time I had a 386, I charged the thing to the poor power of the pc. but today the speech is different. and if autocad today makes me retini without problems... with the 3d you continue to have some problem.

you realize the poor video management of autocad watching video tutorials on youtube. until the example concerns a few entities see the cursor move smoothly. with more complex files, those movements get less fluid.
I speak of 3d, with 2d instead it is all very fluid.

if you look at the 3ds max tutorials, and also other programs, you will notice a slider movement fluidity that autocad is dreamed of. I always talk about 3d.
 
But I don't get your problems. will be a file cleaning problem or know how it works internally.
I make 3 examples:

1) I get a light 800kb file but it takes over 3 minutes to open.
Why? they have always used the same file from the night of time and everyone has erased previous images if ever "stack them". 352 images attached but not reported. another 10 minutes of selection only to detach them, but once "clean" flew (obviously)

2) relatively light file (2-3 mb) but lattice "dot". a retino is nothing but the infinite repetition of a pattern, in that case so many distant points.
but for each point there is a need for a definition of pixels that represents it, which must be recalculated to every minimum shift/zoom. the same retino but anxious 31 (the lines) is infinitely faster. result: retinal changes and sketches without problems.

3) I get a file with 6 tables a1 (a misery for my standards) - weight almost 76mb. 76mb!!
open and found? the genius of turn inserted the pictures of the cover and logos as ole objects (it copied them from word and glued them inside, chissenefrega) - 6 images and 6 logos.
save images as external files and hang up, the file flies and weighs (between external images and dwg files) only 1.5mb.

begin to work "clean," and then start talking.

for the record: Unlike other software, autocad only uses directx or opengl. this means that an average gaming card (200€) under autocad is more than good. suffer a peline in 3d management (but not so much). then you can take firepro or picture and spend 6-7 times more for the same (identical) hardware, with enabled optimized drivers.
time ago a software modification was made to transform a 4870 radeon into a firegl I don't remember the number). we talked about an economic difference of 300€ for the 4870 against the over 2000 of the firegl.

3ds has a different engine, voted at 3d, but on 2d is a total gross. if you do things "artistic" 3ds is perfect. That's why he was born. but if you do "technical" things... "measurate" then 3ds is useless (who knows why you draw in autocad and then after you walk in 3ds).
is management of grips, snaps, coordinates of overlap between objects etc etc.
Let's make it "study" autocad and see how slow it is. always taking into account that 3d is an addition, not its main vocation.

you are right, and I can assure you that you always try to work as clean as possible. Regardless of this, the speech was another, i.e. autocad that grinds what and the pc that sleeps quietly (regardless of the type of sitema: intel, amd, nvidia, gaming series or professional series)! Obviously in a product widely used at a professional and paid level I would not hardly say that it would be the least to have a program that functions and is optimized.
is, in my opinion, useless that after a year of research and development add the x key to make y and change the color of the interface, without giving an eye to everything else.

That's always a good rule.
But I repeat, build four bonfires of a normal house and start filling them with tiles... and then we talk about it. At some point you will be forced to transfer the design to another program.

the fact that autocad raises compatibility issues between one video card and another, means that those who do not own that card will meet the problems we are talking about. and they are very disliked problems. as it says well thelittlesniper from a Mr. program like autocad you expect something extra.
for all the rest... so much hat. autocad remains the best replacement of the old tecnigraph. I would not replace autocad with no program to draw a plant, quota it, retinarla etc. even building a 3d from the same plant is easy to a certain point.
 
designing "on the clean" helps, but with the massive use of solids or surfaces curve However, problems start, I think I just mitigated by using high-performance video cards.
As long as autocad uses only one processor we have no chances.. .
 
3ds has a different engine, voted at 3d, but on 2d is a total gross.
If I don't remember correctly 3ds was purchased by the autodesk only later. that I remember, the autodesk in the times of autocad 10... It was just autocad. in the studio I saw some of my colleagues working with archicad, practically an autocad embellished with menus, including icons that allowed you to insert already prepared blocks (for example for furniture, electrical plants and vegetation for plants and prospects etc) all easily accessible through slides. autodesk later bought 3ds max and also maya, until it came to count an extended park like the current one.
autocad, at that point, began to be "ingraved" with things you saw before on 3ds max, such as the cube icon on the top right to rotate the views, or the possibility to filter the selections according to points, edges, faces of solids or surfaces. things that previously did not exist on autocad.

Maybe that's why autocad remained the autocad of all time. what has changed is its graphic dress, and some accessories (such as the cube of before) on which utility I have serious doubts. as well as the power of today's processors.

on the gross work in 2d on 3ds max I agree with you. I tried to exploit 3ds from this point of view, but it doesn't give me the same mastery that autocad instead gives me.

He doesn't give it to you because he doesn't.
3ds is dedicated to managing solids, so it is designed to manage them, but lacks any geometric reference (setting a solid in 3ds, becomes a calvary).
It doesn't even have commands you can give from keyboard (it only has shortcuts, but you will understand.. . )
However, on the other hand, it manages lights, hierarchy, constraints. remember that 3ds was born for animation (in which I think it excels, keypoints and path manageable in an intuitive way etc.) and to those who had to realize an animation it was highly cared if a solid was 14 or 14,2 long. then incorporated "as addition" interface functions with acad.

autocad was born for the technical design 2d, then added the 3d, on which it does not excel, but is precise to the same as the technical design.

I'll give you a trivial example. quite often, I found myself having to do soil treatments in the underground. a series of fan-shaped perforations in space, type explosion to understand us, which had to reach but not touch (tolerance 5cm out of 40m) a circular-shaped tunnel (a cylinder) oriented in space compared to the drilling point.
the perforations are always made blind, i.e. without control excluded angle and depth (of course, they serve to dig, so you do them in the ground without seeing anything).
If you're long, you're missing the gallery, if you're short or badly oriented, don't solidify the ground, so when you dig, you'll find yourself a river of groundwater acha, with realistic risk of collapse.
to me is asked vertical angle, horizontal angle and length of perforation, and a medium-sized treatment stands out on the 40-50 holes-
never topped one. Do it with 3ds, you whistle me when you're done. .

are different programs, voted for different things.
if you want to use autocad to draw the house in 3d, complete with tiles, decorated furniture, Venetian doors etc, I greet you.. .
if you want to draw the perforations of the treatment with 3ds made before a solid professional insurance.

with 3ds it is possible to be precise in the same way, but I say the truth, I also prefer autocad. It's even more intuitive from this point of view.
I wonder what's more than 3ds that allows you to have walls and tiles and be able to turn views without any problem.
that is the question is not the fact that one was born for the 3d and the other not, we talk about quantity of manageable entities without having problems at video, regardless of how the program is built.
