KICK-ASS posted a topic in AutoCAD 2D Drafting, Object Properties & InterfaceHi, I'm new to the Forums and this is my first thread. I have been assigned to draw an isometric and 2 dimensional view of a sprocket. It has to be to scale with the sprocket given to us. I can't figure out how to measure it, much less start it. My guess is to start with the center, but I can't even measure that. When I figure out how to post a picture, I will. What I can tell you so far is that all I am permitted to measure with is a 6" CEN-TECH Dial Caliper. Not sure of the name, but I can describe the center hole(s). The center looks like a gear with 6 (flat) teeth. Above that (I eyeballed the bottom of it at about 1/8 in. away from top of center) is a circle that my caliper reads at 0.276 in. in diameter. It has 14 teeth. Sorry for the long explanation, but I want to make sure the responses can be accurate as possible. When I get the pic, I'll post it. On this thread. THANKS SOOO MUCH!!!
Puzon posted a topic in AutoCAD 2D Drafting, Object Properties & InterfaceHello As a hvac calculation engineer i often need to measure quickly pipes length and ventilation ducts area. Measuring pipes lenght is quite easy with qselect + tlen.lsp, but, so far, i've no idea how to measure ducts area quickly. I'd like to add that ducts surface seen in 2D would satisfy me and i only talk about 2D drawings. Do You have any idea how to do this measure? Maybe there are lisp routines that could help?
