In my scheme of things, I always use magenta for construction lines, hidden lines are always red, center lines are always yellow, etc. And once I drew a gear of any given size, I merely had to select it, copy it, and use "snaps" to drop it into place wherever I want it.Īnother time saver with most CAD programs is the ability to create multiple layers that can be drawn on independently of the others, you can make them visible or invisible, and assign colors to each layer to separate them from other layers. If I had to redraw the basic machine parts for every gear combination, I probably wouldn't do it. This image only shows about 1/3 of the whole group. Here is a pic with another example: Once I drew the machine frame, I simply made a string of copies to use to experiment with various gear combinations. I don't have to start over just to make some modifications.
When I'm finished, I can draw a box around the design I want to use so it's easy to find, and I still have all of the other versions. As a design progresses, I have in front of me the entire chronicle of the changes. And I can do this an unlimited number of times. Here's what I like about CAD: I can draw some device or other, then copy all of the drawing to another location on the screen, then start making changes without losing any of the original. Will it, or wil, it just give him nicer drawings ? What is your views on it ?I work from anything from a mental image to a paper sketch, paper drawing, or CAD drawing. I heard one fellow say, I have CAD on my computer, now I can design things. I have made lots of parts that were drawn on CAD. not so goid to expect others to be able to understand them. I do my drawing with pen or pencill, often on napkins, and it works for me. Now I am curious, what will CAD on a basic level do for you. If I burn it up with welding sparks, I can print another. When I'm done, I can print my drawing and fabricate from it. I've tried a few other things (Sketchup, Visio) but I am too impatient to have to learn a new tool again, with a whole new (usually hideous) user interface. No, it doesn't read DXF or write it either.
I can easily PDF my drawings and post them online, and others can easily read them, at least if they know how to read blueprints. This means I can go copy from earlier projects, or parts of one. Of course, after the project, I generally don't delete the spreadsheet or drawing files from disk. I enjoy the shop math as much as anything else. I draw each line exact to the mathematically calculated length. I start by deciding on a drawing scale that will allow me to draw my piece on an 8.5x11" sheet.
It's strictly 2D, not smart at all, all dimensions must be added manually, etc. Years ago when I worked for a big software company I got very used to a drawing tool called Adobe FrameMaker.
