Isometric drawing from front, top, side views

Anonymous — Tue, 31 Oct 2017 19:16:38 GMT

Hey, AutoCAD isn't my greatest skill, so this may be fairly basic, but I was wondering the best way to go about drawing up an isometric view. I have the front, top and side views finished, but I don't know the best way to get started here.

I'll attach the drawing so far if you'd like to take a look, and any help or tips would be appreciated. I'm using 2014 if that matters. Thanks

Personally, I'd build a 3D model of the part then set a viewpoint of 1,-1,1.

For true auxiliary projections try here or here

Hello,

Honestly, your general approach is wrong, in my humble opinion.

Everything you have done is 2D and in one plane, and you can see what I mean if you hold left shift, hold middle mouse button and move mouse around a little. So basically, you can't make isometric view easily now.

If you try drawing your model in 3D, then you get side view, top view, isometric view or any other view simply by one click. This is however a little more advanced topic.

So now you can draw your isometric view in 2D, like everything else, the way you would do it by hand. In the long run, I strongly suggest learning how to draw 3D models because that's one of the most important advantages of CAD.

Hi @Anonymous,

I see that you are visiting as a new member to the AutoCAD forum. Welcome to the Autodesk Community!

If this was my exercise, I would draw a 3D model and then use Viewbase to project the desired views.

I attached a link to a Facebook video that might get you started on doing this process the "old-school" method.

[EDIT] I made a quick video for you that shows how the 3D model might be the better approach. I quickly constructed the handrail portion of your model and then used VIEWBASE to create the top and front views. I then also created the ISO view.

I agree that 3D is the way to go, but since you asked about isometric drawing; I like the method where you start with an isometric box or boxes that are the largest outer boundary of the object. Then you start measuring and connecting one point to another. I have started one that I am attaching but I didn't measure anything, it is just a sketch to illustrate how to get started.

If you can picture it in your head, you can create isometric views, I had to do this back in version 1.1, but 3D has helped a lot as well.

Hey thank you everyone! My boss made the original drawing and told me to figure it out, despite me having like no experience with any drawings or 3D autocad. I appreciate showing the handrails as I was having trouble picturing the drawing even. I drew up a rough sketch, but it isn't correct. I'll keep working on it, thanks.
