View Full Version : Question about drawing an isometric model v.2002
28th Aug 2003, 06:19 pm
I am interested in drawing an isometric mock up of a closet design. I was wondering if there are any helpful tools that AutoCAD 2002 has that will help me draw this isometric mock up in isometric view. Or is this type of thing simply considered a wire frame 3-D drawing, and in which case, will tha be too hard to do and not worth my time?
I am doing this to show somebody a design I want to do. Just looking for some good advice.

Don't know about tricks,but in CAD2K you can right click the snap icon-settings-snap and grid-snap type and style.Then choose isometric snap in the grid snap section.You will now be able to draw using an isometric view.You can change your grid and snap spacing to suite your drawing.The snap and grid are vital tools for speeding up a isometric drawing.When you have ortho on F8,you can then change the angle your lines snap to by using the F5 key.

hmm interesting. I am not really sure what snap to isometric means yet. know it changes my cursor to a isometric angled cursor, but that is about it. One type of "trick" that I meant was using that ortho function. When I have ortho on, and I have it set to snap Isometrically, the ortho will draw a straight line isometrically. Unfortunately it only goes one 2 ways and not all four angles in an isometric drawing. What's the grid that you are talking about though? If it can help, I'd love to know what it is.

I do not have much time available right now but I can come later for further comments if that does not hellp you.
- in ISO DWG. you have only 3 isoplanes> left, right, top and 3 angles > 30, 90 and 150 degrees.
- when you mark your SNAP&GRID and ISOMETRIC SNAP, than the dots on your model have changed on a 30 degree angle and so your crosshair.
you can make them visible or not by presing F7. It is your pick when that suits you.
- to change the ISOPLANE to LEFT ISOPLANE, RIGHT ISO AND TOP ISO, press F5.
Tips: some people find useful when iso.dwg. to increase the size of the crosshair to 100 per cent.

A quick visualisation of above mention it>
note the angle of grid in the 2 examples
use ORTHO in relation with F5. hope it helps

Exactly you need to hit the F5 key to see all the alternative isoplane angles that you can snap to.

Ah yes that F5 key is very useful. What command is that F5 key representing? I just want to know because there might be more useful commands in that same vicinity.
Thanks a lot that is exactly what I'm looking for. I another question, if I go to the Grid options where I set the "snap to iso" setting there is an option for changing the "snap angle" right underneath the snap Y spacing. What does that option do for me?
If you come up with any other "tips" that would make it easier for me I would greatly appreciate it. I don't know how to set the cross hairs to 100% but I'm still working on it, if anybody knows I could use that too. The pic really helps too, thanks a lot of all the help.

SNAP ANGLE is used when working with unusual snap angle, like for instance 45 or 78 or whatever comes into your mind. Type in the unusual angle and than press OK. You will see how your GRID DOTS use the angle you typed and so your crooshair. A similar result can be acheived by changing the UCS instead of the SNAP ANGLE.
- to change your crosshair: TOOLS> OPTIONS> DISPLAY- CROSSHAIR SIZE ( move the little thing to max) :lol: > OK.......ta da

Thanks Orbit. One last question and this one has been bugging me. So if I look at your pic, let say for example that I want the depth of the left-face of the cube to be 2', and also I want the right face of the cube to be 2'. How do I do that precisely. Obviously it is easy to set the height of the cube to 2' but what about the sides...if you just use offsetting it won't work because ACAD sees the drawing as a 2-D drawing with y-axis elevation.
So what I did jus for example is I offset the center line (vertical) to 2' to the left, and then I extended it way past the top of where the cube should end. Then I intersected that line with the line running from the top of the middle vertical line to the depth of the cube. By doing that though, I've created a depth (that as far as ACAD can tell) is slightly longer than 2'. Of course the linear dimension is 2', but not the hypotenuse - am I making any sense?
So I was wondering, when people do isometric drawings do they want each element to be the actual length (meaning the line representing the depth, should be 2' if you checked the properties), in which case how do you do that? Or do people just measure the linear length of the lines? If this doesn't make sense please let me know.

DSQ, I really do not understand your question but I have tried to make an iso closet for you and see for yourself and indentify the problem.

ok maybe this will clear it up. In your picture, it appears to have an 8' front. My question is simply this, how did you draw that line? If I were to check the properties of that line would it say 8'?
Can you give me a step by step account of how you drew that line? I don't think I am so lost as to not know how to draw anything, it just seems I can't explain which part is befuddling me.

The answer is yes. I DIM each line for you after your requested measurements after reading your new post.
Target for today: you will be a master in ISOdwg. :wink:
I will send to you privat on how to do things and maybe the DIM. if you need it, because it is a bit special in ISO.
It can be annoying for people who already know how to do things to open multiple messages about the same topic. That is why we help each others in privat from a point.
