use of the graphic tablet in autocad

[Pier46]

Good evening my name is pierluigi, in life I am an archaeologist.
I open this post because I have a problem, for work use autocad, one of the main commands are polylinea and sketch.
made this premise gave me a graphic tablet (model gaomon s260) connected to the pc works instead of the mouse is quite easy. problems arise when I try to use it on autocad, from display > tablet > if I do on it tells me that the device cannot be recognized as a tablet. it would not be a problem in itself since the pointer still moves when I move the tablet stylus. but if I try to use a command it doesn't really go I track the random segments or draw the shapes with dimensions that I don't impose.
Can someone help me have such problems? ?

There is little to do. modern tablets do not work with autocad. these were compatible tablets

 

[Pier46]

I think it's a little weird though.

 

[Tristan]

What's wrong with you? that in autocad by now the tablets have not been used for a long time? if the main commands you use are polylinea and sketch, maybe autocad is not the best tool for your craft

 

[Tristus]

I think it's a little weird though.

a professional technical study will use tablets like that in the photo posted by tristan. all the others serve to paint with photoshop programs.
the first time I saw a digitization of a cathartic map they worked with tablets like that in the photo. several years ago.

But at the time the programs to vectorize the results of a scan were very limited and depending on the map the results were bad, it was done first with the graphic tablet.
but the "mouse" of that tablet is very precise and the work went on sent.

 

[Pier46]

the point is that the program should see me the tablet as the mouse, the fact that I deal with archaeology and it happens that I have to work on layer plants, or polishing of wall photogrammetry and not always the architectural elements are regular here why use sketch. so I thought the tvoletta could be useful. remains the fact that the program should see the pen as the mouse, and in fact it works but when I take a flicker command

 

[Tristus]

the tablet you have actually replaces at the mouse, to the point that you can even open the browser and navigate with the pen use. And so I guess the same pen allows you to open autocad menus. but an account is to navigate the menus, and another is to appropriate a specific command (such as sketch or polylinea). in fact autocad tells you immediately that the tablet is not compatible, or allows you to explore the menus, but does not include the command you select.

you should use photoshop to create free hand lines with your tablet pen, vectorize the result (always with photoshop) and import the vectorized result on autocad.

something like that

 

[Pier46]

Thank you.

 

[Tristus]

This video is perhaps more explanatory.
he takes an image (any icon) and vectorizes it. i.e. transforms that image (which can be a photo or a set of lines drawn with the graphic tablet) into something that can be imported on autocad in vector format. he uses adobe capture but can also be done with photoshop.
unless you have special needs, you can do without autocad, because autocad is the least indicated program to work "by free hand". But you can do that job in photoshop and import it on autocad in vector format, if you are required to view it on autocad.

 

[Tristan]

without going to photoshop, you might need a gimp or inkscape (better the latter exporting directly to dxf) both opensource

 

[Pier46]

the fact that I do everything with autocad because I find it more performing from the archaeological design of the finds to the transposition of the reliefs and then because in superintendency they want the format both the cad format and the pdf of all, goes bhe the graphic tablet does not know how to make sin. Thank you very much

It's not exactly like that, I started with the table as a tristan photo, then I took wacom a5 with a template that replicated the layout of the table, I insisted not to use the screen menu.
2 weeks time, I removed the template and used the tablet as an extremely accurate mouse, finally passing to the screen menu.
the wacom tablets allow to define the ratio of the tablet area / screen area, I do not know that quoted by pier46.
I'm sure you can't recognize it as a tablet, but you only see it as a mouse.
are decades that I use autocad, inventor, rhino and all the rest with this pointer, never had problems.

Also my me defines the job area report as I said as a mouse only recognizes it that when I take a flicker command just incomprehensible. I tried on a 2015 version and it works great!!! So I'm leaving with the idea that my version is the real problem

 

[Tristus]

Are the drivers installed?
I tried a few weeks ago with a wacom bamboo of my nephew, but I must honestly say that I am not comfortable at all. not on autocad because he did not install it, but on photoshop.
Of course, to trace the pen freehand is ideal, but for all the rest personally I find it uncomfortable. but surely you have to take your hand.

I wouldn't forget anyway. rather than leaving the tablet unused and damaging with the mouse and the sketch command I would immediately open a program to vectorize the images and work with that to then import the result of the vectorization on autocad.
I say this in principle, not knowing how you currently acquire vectors.
Before you talked about photogrammetry polishing. amounts the image file (or raster) on autocad and recalc above? Is it possible to see any picture of the work you have to do? so that you can be more accurate in the councils

then I upgraded to autocad 2021 and now it works almost well, it does not recognize me well for example the keys on the pen (I had put the pan to move me and that occasionally does not take it).
exact as documentation we use the fotgrammetry and on that we draw the relief. Unfortunately there is no vetoralization program that can transpose a medieval wall. masonry is made of strongly irregular shells. Unfortunately the relief is part of the excavation documentation so it is to be done, and this brings us back to the tablet. I can only use autocads maybe there are more efficient programs for this type of work but so I can use that (even because I don't only make it relief of the lifts but also architectural relief) and that use. Anyway with the tablet and the sketch command I found myself very well!! Maybe wacoms are more compatible with the ac than the brand I got!

 

[Tristus]

Perhaps there are more efficient programs for this type of work

for the architectural relief, as well as for the archaeological one, the photogrammetry is encountered.
how is it possible otherwise to get a 3d relief with the method you described?
This is an example of a section of a mantovana I detected for tests, taking 35 photographs and feeding them to the zephir3d program (but it would be enough much less) from a distance of about 3 mt, from below. processing takes a few ten minutes.
the result you get is a 3d model consultable also by autocad.
it is also possible to export the pdf 3d.

probably just generate a photoplane to be recalculated with autocad. technology of last century but for archaeologists maybe it is enough

Yes, but at this point autocad used to track with the sketch command becomes almost an obstacle that loses time. you could get the same result of "polishing" with a photo-touch program that goes to track the contours of the photo and then vectorize the result, maybe by cleaning it from the excess lines.

or by taking a series of photographs and feeding them to a photogrammetry program you could, once you got the 3d model, view it with the same perspective of each of the photos taken. you could then get a non 3d figure that includes both the photo and the 3d model displayed though as everything on a floor. The plan picture you were talking about.

[Pier46]

that is exactly what we do, photopiani (I use metashape ) but the problem is that we also study the masonry because they are detected (I specifically deal with ancient metrology) there is no program that is able to vectorize the elements of av masonry and many things are noticed much better after we designed the relief. just this morning I realized by polishing a masonry that there was a walled passage very well that we had not noticed on the yard in model 3d

here are very good users, so much of a hat, but they do not know what it means to make an archaeological design, to be folded hours in a square etc., there was a system conceived by a friend of mine that allowed you to draw from computer, had conceived it in autocad under dos, with small graphic planks as large as a drawing table, then in windows we went directly to raster design (application of autocad) I forgot in a Greek necropolis excavation in just 50 square meters we found about 600 points, so the fatigue you have to do the same, only you do not know folded hours and hours
