I have been working with LaTeX for some time and I have to draw some diagrams or draw geometric shapes on more than one occasion. So my question is:
Someone knows of some tool that facilitates this work. That is, maybe some GUI that allows you to generate the latex code to insert into my main text.
As indicated in a comment, you can use Latex Draw to make the graphics in latex documents. link
Additionally about the question of whether you can generate a pdf from the origin text, if you can with pdftex test1.tex
Additionally you have the following commands
tex test1.tex : convierte un archivo TeX a DVI
pdftex test1.tex : convierte un archivo TeX a PDF
latex test1.tex : convierte un archivo LaTeX a DVI
pdflatex test1.tex : convierte un archivo LaTeX a PDF
