Re: my second attempt with only one error, getting better

Hi
I downloaded the whl file from https://pypi.org/project/sympy/#files, then open you terminal as amministrator and navigate to the folder where you put your file.
At that point I use a pip loader with the command

Code: Select all

py -38 -m pip install The_file_I_downloaded.whl
.
In my case I use py -38 because I have different versions of python, otherwise if you work with just one version you can use

Code: Select all

python -m pip install The_file_I_downloaded.whl
.
In the same way you can add others libraries like SciPy and so on.
So after you installed the library you can check if is in with

Code: Select all

help('modules')
from the python consolle and the library SymPy should be among all the others.
From the terminal to go inside the Python library I use

Code: Select all

py -38
(if you run just one version

Code: Select all

python
).

Hi to everyone.
This is te latest post of the original code.
I haven't test properly yet; seems ok.
let's try.
here is the code
PS when you insert your function in the box make sure you use the lower case 'x' if the function is a constant just insert your number

Code: Select all

Post by sibelius »

hi

please add the following line

Code: Select all

P = E.Placement=App.Placement(App.Vector(XT,YT,ZT), App.Rotation(RX,RY,RZ), App.Vector(VX,VY,VZ))
after

Code: Select all

E = face.extrude(Base.Vector(0,EXT,0))
near the end of the function to gain control of dispacements.
PS there is a mistake in the names of rotations; to late for mi to fix now, I'm going to bed

hi

This is the final code (for the moment) and the file.ico to add in the toolbar.
PS remember to cancel the extension jpg from the file to be used
