is there any cad programs for the cfx out there?

[huhn_m]

are you dreaming!?!?!

It seems impossible to make a program this complex with only 22KB of ram!
Noone is able to do this. it might be possible on a AFX but only with problems.

[rjstephens]

CAD on cfx??

btw it would have been ok to post this in the main forum (i think) that way we could get our posts counted for it.

It isn't impossible, it depends what your trying to do.

a modified 3d grapher program might be worth a look. i suggest you try CFXYZ
(hint hint: i'm suggesting you modifiy it yourself)

Splendid

[CrimsonCasio]

I moved it! yea!

[Pixter]

it shouldn't be too difficult to difficult to make a cad program, you will have to make list that contains all the data, a programm to add data and a program to draw it all.

I will give it a try (for the cfx9850gb+).

btw, is there a command or something that reads the viewwindow settings? (I don't mean adjust or something)

[BiTwhise]

under VARS you have view-window, with xmin, xmax, xscale ,. ,. and so on

[Pixter]

thank you, that was a quick reply

[Casto Productions]

What exactly are you hoping to use this CAD program for? You might be better off just using one of the better drawing program.

[Pixter]

I just want to make this for fun. And I don't know why bob vila needs a cad program.

I made something that let you add points by typing the coords of the point (X,Y,Z). And my second program draws everything.
Tomorrow I'll add an option to add lines and maybe boxes and some other shapes.

[CrimsonCasio]

If you need any help, dont hesitate to ask, I made a very simple cad program about a year ago so I have some experiance with the subject.

for instance, might i suggest that you have 3 layers which the user can use to draw on, each below the other, since the colors themselfs are layered you have but to draw the top layer in orange, the middle in green and the bottom in black. This way you can erase layers at a time.

sheesh, I'm inspiring myself... you could have the top layer be the "final" layer, having everything else drawn benith it, then you could have a command that scans the entire screen and where ever there is a pixel it places a orange pixle on that spot, therefor moving things from the bottom layers to the top one! Its likie PhotoShop for the casio! if you dont do this then i will, I dont know why I didnt think of it before.

[Bob Vila]

i was just wondering because all my friends are into cad, i havent taken the class, but they all have ti's and i think that i could probably translate it.

[CrimsonCasio]

not if he does as I said, Ti's dont use color.

[Bob Vila]

not if he does as I said, Ti's dont use color.

i know, but couldn't i take the color out?

[CrimsonCasio]

on the color graphing calcs the screens have 3 layers of color: Black, Green, Orange. black is drawn on the bottom most layer and all other colors are drawn above it, therefor a black pixel cannot overwrite a green or orange pixel. the same goes for green, except it can overwrite the color below it (black) and orange can overwrite all the colors. however, there are ways to overwrite one color, leaving the rest so you could clear all green pixels and leave the orange and black ones: thus creating the impresion of layered drawings.

if you removed the coloring then all pixels would be cleared instead of just one color. do you see?

[2072]

Sorry for my stupid question but what means CAD?

[CrimsonCasio]

Computer Aided Drafting/Design/Drawing

[rjstephens]

nice trick with the colour, isn't the CFX blue, green and yellow

and WHAT COMMANDS do you use to do this magic layering trick?

[CrimsonCasio]

I will create a small sample program and post it to demonstrate, check back later.

And technically its blue (or black), green, and orange.

[Brazzucko]

I don?t think that one cad program its necessary for the AFX/CFX calcs, anyway for me is more easy and best to make pics in the PC, then transfer the pics to the calc, but anyway if you do one Crimson I?m interested on it?..

[Pixter]

Does somebody know how I can add something in a list without deleting all the data?

for example:
I have a list with 10 items thgen I want to add an 11th item without using the dim command because that command deletes everything.

So my question is: How can I make a list of 11 items from a llist with 10 items without deleting the 10 items I had ?

[huhn_m]

do the following to increase list 1 to one more cell and not delete its old
contents (but it will delete the contents of list 2)!

List1->List2
DIM List1+1->DIM List1
FOR 1->A TO DIM LIST 2:LIST 2[A]->LIST 1[A]:NEXT

Thats it.

[BiTwhise]

with the afx you simply append to the end of the list, by refferencing the last + 1 element

[Pixter]

Thank you huhn_m.

I will post my program in an hour or two, it will only support points and lines then and it has no special functions.
There are two seperate programs (I have not "combined" them yet), one to add data to the list and one to draw the lines and the points.

Special functions such as rotating the view and the "layer trick" of crimson will be included later.

@bitwhise--> The CFX gives a dim error then

[CrimsonCasio]

Demo of Color Layers

[Pixter]

CAD


Run "START ME" if you want to use the program, it makes list 1, list 2 and list 3 the same lenght and it makes sure that there is something in the list, otherwise it gives errors if I use the Dim command.

Use "ADD" if you want to add a point or a line, use "DRAW to draw all your data.

There is not an option to delete points and lines yet. The program is not user-friendly yet

Please tell me if you have any ideas or comments

Crimson, I will add your color trick tomorrow

[CrimsonCasio]

I think I am going to try something with this, when I was making the demo I discovered that the colors do not overwrite each other as I had thought, but rather just display over or above each other... this gave me the idea of using a orange flash screen and drawing pictures behind it then just wiping the orange leaving the picuture revealed.

[Killer83Z]

Orange Flash screen. Yeah, with Orange Graph Y<=1 (or the other way around, then vice versa). Still, you can see blue drawing behind it...

I knew on the monochrome version of the cfx 9850g it was even cooler, because it was a black screen, and you could perfectly draw behind that "mask".

[CrimsonCasio]

you can see stuff behind the orange? I cant.

[huhn_m]

Hi!

CAD (fixed)

I changed some things. you can save memory if you use k/M/G instead of 1E3/1E6/1E9
you find it in OPTN -> ESYM

k = Kilo
M = Mega
G = Giga

They are constants containing the values 1.000/1.000.000/1.000.000.000 look at the new sources!

The prog is GREAT! (but a little slow)

If you draw from or to x,y,0 the graph is not shown!

*EDIT*

you have to right click on the link and choose "save as" dont know why clicking won't work

[Pixter]

Thank you huhn_m

If you draw from or to x,y,0 the graph is not shown!

What do you mean with this?
Today I'm going to fix the prog so that it uses the axes of the calculator instead of the axes I use now. If I do this, it will be possible to move, or to zoom out.
The only drawback is that the program will be a little slower.

Another thing that has to be done is a program that allows you to delete or edit points.

O and I'll add colors


What are the excact differences between this:

F-line 10,10,20,20

and this?

Plot 10,10
Plot 20,20
Line

I know that F-line is faster, but are there other differences? I tried some things and I discovered no differences

[rjstephens]

yes tehre are other differences:

F-Line 10,10,20,20-
would take 13 bytes

Plot 10,10-
Plot 20,20-
Line-
would take 16

you save 3 bytes!!

[BiTwhise]

Plot stores the coordinates of the plot in your global X, and Y variables,
F-Line does not

[huhn_m]

Thank you huhn_m

If you draw from or to x,y,0 the graph is not shown!

What do you mean with this?

Well go into "add" choose 2 and type

0
0
0
30
30
30

Then exit and draw the things! You'll see nothing!

[Bj2c]

the best cad , mercury generate code while your drawing and then convert it to cat

[Pixter]

Cad programm

I didn't solve the Y=0 bug yet, I really don't know why this happens .

The program "GRAFICAL" is just a test of how to add points in the grafical environment.

Everything works the same as it di when I posted it last time, except this version uses colours.

[huhn_m]

it's a bug with the calc i think. at least on the CFX you weren't able to draw lines from/to some points no
matter if a part was vissible the whole think was not shown
