need help converting 3D to 2D

[Loutro]

I've done something strange and cannot figure out how to solve it. I downloaded a 3D file of a chair and within the file I copied the object three times in order to create three paraline views (plan, side elevation, and front elevation. By way of changing the views, I turned each copied object until it appeared properly on the screen--this of course changed the ucs for each view. After flattening and overkilling, then simplifying each drawing to a satisfactory state, I was ready to print to pdf.

 

Moving to paper space, I created a viewport for each of the three views, but for some reason, the scale could not be set properly: even setting the scale to 1:1, the object became very tiny on a letter sized sheet. I checked the measurements in model space to be sure that I hadn't scaled anything, and everything is fine there.

 

Problem 1.

Why can't I set the scale properly in paper space to print at a reasonable size (scale should be about 1:10 or 1:20)?

 

I decided to go back to model space to try to re-orient each drawing so that they are all in the same plane, but I could not rotate as needed. The screen shows one drawing properly (ie. x and y are in the normal position), but the other drawings appear as simple lines, one vertical and one horizontal. I know that I need to rotate each 90 degrees and then change the view, but I am unable to rotate. I have never worked in 3D cad before and clearly am missing basic understanding of how to use it.

 

Problem 2.

How can I re-orient all three drawings so that they are in the same plane, and reset the USC to the standard position so that the z axis is not a factor? I want the document to be a simple 2D cad file with the three views of the file lined up properly next to each other.

 

I have attached the file. It was created using Autocad 2011 (it is a french version, Im hoping it will open without any issues).

 

Many thanks to anyone who can offer any assistance.

Did you bother to check any of the chair dimensions in model space? Looks to me as though the chair is sized for an ant.

 

OK...I have a top, front and side view of the chair established in a paper space layout. I had to set the viewport scale to 100:1. What's next?

[Loutro]

yes, the dims appear to be correct, about 80 cm tall.

[ReMark]

What's next?

[eldon]

I would suggest that Rotate 3D would do the trick.

 

P.S. ReMark doesn't know about Metric Ants

Ok, to help me for the next time, when you say that you changed the viewport scale, is the the tab at bottom right that shows the scale when the viewport window is selected, or is it another setting somewhere else?

 

For practical purposes, the scale is correct now in paper space, I'm all set, but I would like to know how to re-orient everything in model space so that all drawings are oriented the same way with the UCS in the default position, my question 2.

 

Thanks!

I've added an isometric.

 

Lou: You should have your viewports on a separate layer so the display can be locked.

[Loutro]

thanks, did you attach the updated file, or is this a screenshot?

[ReMark]

Reorient your UCS using either the Dynamic UCS option or if you want to do it manually use the 3-point option. I'd also recommend rotating any 2D view that isn't already in the "default" X/Y UCS to it. The 3D chair can stay "as is".

 

eldon posted a screen shot from the looks of it.

[eldon]

thanks, did you attach the updated file, or is this a screenshot?

 

It was just a screen shot to show what Rotate 3D could do. I leave you to explore the command.

Remark, thanks, could you comment on what you said you did with changing the viezport scale? Is this different from changing the scale with the pull down menu in the bottom right of the page that appears when you select the viewport? Could you attach the changed dwg so I can take a look?

 

Thanks

There are at least four different ways to change the viewport scale. Click on the viewport then...

 

1) Change the scale in the Properties dialog box.

2) Use the Viewport Scale feature in the lower right-hand corner of your screen.

3) Use Quick Properties.

4) Via the Viewports toolbar.

 

Take your pick.

Here you go. have fun.

Going back to your viewport problem, I think that your viewport is sized in millimetre units, whereas you are drawing in metre units.

[Loutro]

ok, that would make sense.

 

Thanks to both of you for your help!
