Need help with drawing certain shapes using AutoLISP

Anonymous — Tue, 03 Dec 2019 14:42:50 GMT

I need to draw these shapes using AutoLISP, no idea where to start.
Any sort of help is appreciated.

Is there anyway to convert image drawn with Autocad in .dwg format to AutoLISP commands somehow?

Trace them once then use them as blocks?

From what I see, code is not needed for what you're asking. If you're wanting to convert images to vector look into Adobe Illustrator ( result usually needs quite a bit of cleanup ) or if you have 'clean' PDF's use the builtin PDFIMPORT command ( assuming you have a newer version of AutoCAD ).

I must use AutoLISP, it's a task I've got to do for assignment but I have no idea where to start, getting each coordinate and entering it by hand seems to be a pain but I guess there are no ways around it.

@Anonymous ,

You do not need to choose every point by hand. This may be a good time for you to become familiar with the Geometric Functions Reference. People do not want to do your homework for you. Perhaps you can get some code started then return to this thread for further guidance after that.

That's where you can start.

Best,
