Can anyone tell me how the attached 3D representation was created?

[jbird68]

I have a drawing that was created using ACAD 2004. But I am unable to figure out how it was created. I could use a little help figuring out how it was done. This is actually inserted into a 2D drawing with a border.

[ReMark]

Maybe it was drawn as a 2D isometric.

Maybe it was drawn as a 2D isometric.

 

Must be, the sides are parallel, no vanishing point(s).

Can you post the drawing here? I have my doubts as to whether it's actually a model or just an isometric drawing. Although it could be a model with the viewport set to display as 3DHidden. But I'm not sure if 2004 had that capability?

Not necessarily. You can get that same appearance by viewing a 3D model in isometric view. The only time the sides won't be parallel is if you're viewing the model in Perspective.

My bet is isometric.

This is the file. I noticed that the you can select the lines individually, so it has been exploded. I have other drawings where when you double click on the isometric view, it brings up a window saying it is a pictoral object. I just am not sure how teh previous draftsman created it. There are some things like a Destaco clamp that I can't see anyone drawing in 2D isometric. That is in the T890 drawing also attached.

The T890 drawing looks like it was a 3D model and then partially flattened and hidden lines removed. I'm guessing that the other drawing was done in 3D also and then flattened in the same way.

[jbird68]

I would just like to know how to flatten a 3D model so I could use it in representations like I have shown. Can you convert a 3D to a 2D drawing? And if so, how do you choose the correct perspective. I've tried copying the isometric view intoa 2D drawing but when I paste it into the drawing I always get either a front or top view...not the isometric view.

[ReMark]

Users can extract 2D views from 3D solids using any number of commands including Flatshot, Solprof and the combination commands of Solview/Soldraw.

[ReMark]

Part of your problem is you are using AutoCAD 2004. There is no Flatshot command which is what I used to create the 2D isometric of the bobbin I provided you with recently. Seems we have had portions of this same conversation in a different thread. Are you shopping for a new answer? LOL

[jbird68]

All I know is that the views I have posted were created with Autocad 2004. I just can't imagine spending alot of time on creating them in 2D isometric. Maybe if it were just a box shape. How would you get the curves and radii to look correct? I would think it would be much easier to create it in 3D and then use that image in a 2D drawing.

[ReMark]

If they were created using 2004 then the commands available are Solprof and the combination of Solview/Soldraw.

[ReMark]

From Ellen Finkelstein's book entitled AutoCAD 2004 Bible (Wiley Publishing, Inc. 2003).

 

Solview

 

Automates the process of creating floating viewports and orthogonal views - views at right angles to each other.

 

Soldraw

 

Uses the views created by Solview and creates 2D profiles that include solid and hidden lines to represent the profiles and hatching for sectional views. You must use Solview before using Soldraw.

 

Solprof

 

Creates profiles like Soldraw but you don't need to use Solview first.

[ReMark]

An example of a multi-view drawing created using Solview/Soldraw. Viewports were intentionally left visible to show they are separate views.

 

[jbird68]

This was drawn in 3D?

The 2D profiles you see in the above image were created from a single 3D object.

 

I had a copy of 2004 handy so I loaded it up. The Flatshot command I mentioned having used to create the isometric of the bobbin is definitely not a recognized command.

That's what I thought.

Ah, of course.

Here's a trick I use:

 

view the model in isometric:

 

Command: vpoint

Rotate/

 

now set the UCS to the current view:

 

Command: ucs

Origin/ZAxis/3point/OBject/View/X/Y/Z/Prev/Restore/Save/Del/?/: v

 

Select all and copy to your clipboard.

 

Start a new drawing and paste the contents of the clipboard, explode and flatten (or solprof/soldraw/soldraw) as ReMark states

[ReMark]

There is no Flatten command in 2004 that I am aware of but I think you can find it here at CADTutor. It should work.
