to start any designing , standard dimensions are needed, where can i get these dimensions to start designing ?
The word "DESIGN" means a lot... The dimensions which we see as standard dimensions are obtained through a lot of calculations.. e.g. If you want to design a gear for particular conditions.. say for some force and with a certain material... the a design engineer does some calculations regarding beam strength etc. to find the necessary dimensions of gears (like module, no. of teeth).
Then after getting the dimensions we start modelling.
i want do do some conceptual design. i know about the calculations and stuff, but while designing concepts u cant just consider random dimensions, so just needed a rough sketch.
