qball Posted May 31, 2011 Posted May 31, 2011 poop A railroad spike - simple yet three different views. i'm fiddling around with 3D views right now. if i make some magic, i'll bring it up. The head: revolved. The spike (square on one end, round at the point I assume?): Loft. Quote
syzygy Posted May 31, 2011 Author Posted May 31, 2011 the point is, i'm not creating simple designs. if i have to divide a mechanical item into the various shapes from each angle, it gets to be the same amount of work as what i was trying to do in the first place. i generated a cube in 3D view. i tried the spike and got stuck when i couldn't snap to an intersection for some reason. maybe i should just take pictures of these parts and trace them--it's worked before Quote

Working in 3D is actually less work, it is a little slower going while modeling but then you have any and all possible views ready to go. Any editing done is done in one place and then the views are already updated. With multi-views and an iso you have to change it in every one of those views. Quote
rkent Posted May 31, 2011 Posted May 31, 2011 my boss said i could generate an isometric view of a drawing if i have the plan, elevation, and side views (makes sense enough). how do i go about doing this? is there an existing thread i can be forwarded to? (searching "isometric" didn't seem specifically helpful.) do monkeys really throw poop? You can use an iso projection method to arrive at an isometric view of a drawing. This is strictly 2D old school drafting I am talking about, see attached. iso projection.dwg Quote
Bill Tillman Posted June 1, 2011 Posted June 1, 2011 JD Mather briefly touched on the answer to the guys original post. And that is that in AutoCAD you cannot simple take a front view, side view and top view and have the software create a 3D model or isometric view of the part. I believe there are software tools out there which will do something like this but without user input I don't believe there is any package that will magically create a 3D iso view of any part except for the most simple shapes. You can however draw up a really nice 3D model using AutoCAD and automatically, or semi-automatically create orthographic views from it. The simple fact about AutoCAD is that you cannot take a 2D drawing and click a button with your mouse to generate 3D objects. There are many mis-informed people out there who will tell you otherwise. Especially people called "Boss". Remember, BOSS spelled backwards is a Double SOB. Quote

This is strictly 2D old school drafting I am talking about, see attached. Glad you put that drawing up. I had a similar drawing that I've been looking for ever since this thread started and couldn't find. I'd created it way back in the R14 days to teach a class. So, to heck with mine, I'll archive yours! Quote
syzygy Posted June 1, 2011 Author Posted June 1, 2011 The simple fact about AutoCAD is that you cannot take a 2D drawing and click a button with your mouse to generate 3D objects. makes sense, because 3 circular top/left/front views can yield at least two different 3D objects (a sphere or three intersecting circles). i wasn't particularly looking to create something in 3D, merely the 2D representation of such. a 3D model would be far too advanced for what we needed to accomplish. in following that: (no school like the) old school drafting thank you rkent for your attachment. it is quite helpful and precisely what my little noob mind was looking for. if the machine can't read my mind, i'm more than happy to use manual drafting techniques. Remember, BOSS spelled backwards is a Double SOB. XD funny, but being backwards would make them opposite one another Quote

And if anything ever changes, you get to do it all over again, where with 3d, a quick edit on the model, a regen on the layouts and everything updates at once. Quote
