ISO Drawing

[elmways]

Hi

I am doing a autocad course but the part on isometric drawing is very basic.

 

I would like any help on iso drawing but the main thing i want to know is how to create a fillet between two point in iso view.

 

Thanks

Probably not the smartest way but it works for me. I copy the two lines the required distance (= to radius of circle), create an iso-circle using the ellipse command then trim away all the unnecessary geometry.

Thanks, I thinking allsorts of stupid ways that don't work like poly lines or the fillet command. They say the easiest ways are best, i will give it a try.

 

Once again thanks:lol:

You're entirely welcomed elmways.

 

BTW, where are you taking this AutoCAD course?

I simply use the fillet command, I have compared using fillet and using isocircles and the difference isn't worth worrying about. Adjust the size of the fillet for the location.

I am taking my cad course at my local college and then i am following it up by doing a course in Autodesk Inventor.

Ps The tip works fin but now i need to know how to place a array of hole in a circle and make sure the first hole is at the angle i want from the horizontal or vertical center lines.

I tried the fillet command but it would not worl.

You find non-iso locations by locating the x and y coordinates of the end points, or in this case the center points. Always start with an iso square (rectangle) bounding the work, transfer those dims to get an isometric drawing. There is a way to get an actual iso projection but the method above is more than good enough.

 

Are the instructors actually showing folks how to do this stuff or are you just left to your own devices? I think this might be the case of someone teaching the software only rather than teaching drafting with software.

 

And the fillet command works just fine, describe exactly how you are setting up the fillet command, length of lines, fillet radius, etc.

Thanks for that tip on how to place items in a ISO drawing it worked well. Ihave hopefully attached a drawing i have done using your suggestion.

 

Not too bad for my first attempt. I think i can only get better.

 

Back to revision first exam soon. Once again thanks.

elmways,

 

nice one...just be carefull with those tangents.

Hi, I have worked out a really simple method of drawing all manner of complicated objects in isometric. You begin by drawing a flat plane and then you use some maths to 'pull' the plane into the isometric shape. See attached (isometric).

 

This works for any plane parallel to the XY-plane, the XZ-plane or the YZ-plane. I also have a slightly longer procedure for when this isn't the case. (isometric sloping)

I'm trying studiously to avoid drawing in isometric anymore. I've decided to draw everything in 3D then set an isometric view. It makes dealing with pipe bends and complex shapes much easier.

Nice drawing, but I am with ReMark ... I try and draw anything in 3D that I want an iso of and then change the view.

 

For the record, old school books label the view you drew as an oblique because two planes are square to the view.

 

A true iso would have two planes oblique to the view plane, usually the x and y axis and the z axis it perpendicular.

 

Still a nice drawing.

 

I remember doing that stuff by hand with T squares, triangles, french curves, 6H pencils and a lot of eraser shield work!

 

Dang, I feel old ...
