how to scale a drawing?

[Jillymaxo]

I am using the dinosaur version of autocad 14. I know it is old but is working great for what I want to do. I learned on 12 and was using 14 when I stopped working 10 years ago.

 

I am having trouble scaling my drawing. I remember that 1/48 xp is 1/4" scale. 1/64 ?? is that 1/8" scale?? 1/24 is 1/2" scale.

 

Please verify that I am correct. Thanks for your help.

1/96 xp is equivalent to 1/8"=1'-0" scale.

1/48 xp is equivalent to 1/4"=1'-0" scale.

1/24 xp is equivalent to 1/2"=1'-0" scale.

1/18 xp is equivalent to 3/4"=1'-0" scale.

1/12 xp is equivalent to 1"=1'-0" scale.

Remark,

Thank You Thank you! You are awesome!

1/96 xp = 1/8" scale.

1/48 xp = 1/4" scale.

1/24 xp = 1/2" scale.

1/18 xp = 3/4" scale.

1/12 xp = 1' scale.

 

What does "xp" mean?

 

and

 

Would 3:4 scale have a 1 paper unit to 18 drawing units?

 

Thanks

I've never used the primordial version of Autocad of which you speak, these days if you double click into your viewport, making sure that it is unlocked before using the following Z SPACEBAR followed by a fractional representation of the scale you want and XP, the viewport scale will zoom to that ratio. z space 1/4 xp will yield a viewport scale of 1:4, meaning that one drawing unit represents 4 of your dimensional units. Be sure to lock your viewport once you have set it how you want it for your drawing. If you want to set it to a whole integer value, there is no need to express it as a fraction.

 

A 3/4xp scale would mean that 1 drawing unit represents 1 1/3 dimensional units. It will represent the inverse of the fraction, meaning swap the numerator and denominator, and that is what one drawing unit will represent. For 3/4 it will represent 4/3s. For 1/8 it will represent 8/1 .....etc.

xp is the command qualifier for a viewport when your using the zoom command within the viewport.

 

So the following would be entered at the command line.

 

Command: z [enter] 1/48xp [enter]

I find it much easier to simply set the scale using the properties pane once you click on the viewport border (no idea if AutoCad 14 had this or not though). No need to use xp etc then.

That's pretty funny, you make an excellent point! I change just about everything else in my quickproperties palette. Since I always keep my viewports locked, unless I am setting them up, whenever I select a viewport and the viewport scale is displayed, the scale option is grayed out. What a revelation to select the unlocked viewport and see my customized list of scales drop down when I click on the viewport scale!

 

Alternately, I do have my VIEWPORT SCALE set to display in my bottom right hand corner on the status bar. Old habits, unlike old sailors, die hard.

Viewport scales can be changed in a number of different ways. I stopped using the Zoom > n/XP method a long time ago in favor of picking the scale from a drop-down box on the Viewports toolbar.

Thanks for the information and history lesson.

I tried adding a viewport scale (3:4) using the numbers you gave.

 

I can't say it's the right or wrong size; but it doesn't match the handout (it's much larger)

 

Could you help me out?

 

Just as a very gentle reminder, I'm on AutoCAD 2010.

 

Thanks

3:4?

 

What is that supposed to represent?

 

What is it that you are drawing? A floor plan? A detail? Mechanical part?

[ReMark]

What are the rough dimensions on the part and what size paper will you be printing this drawing on?

 

Can you post the DWG file? It would be a big help. Thanks.

 

Is that supposed to be the same as 3/4"=1'-0"?

That's what I don't know. (If it is the same as 3/4" = 1' 0")

 

What do you think?

[ReMark]

Well I'm going to say that is what you need to be using. You do NOT have to enter a n/XP scale factor via the Zoom command to assign a scale to your viewport.

 

Your using AutoCAD 2010 I see. Click on the viewport then look in the bottom right-hand corner of your screen. To the right of the Maximize Viewport icon you'll see the scale for the viewport has been displayed. Use the drop-down arrow to display a list of all available scales. Choose the one that reads 3/4"=1'-0".

 

It might have helped had you posted your drawing file too. For all we know you might have scaled your model space objects.

Mad Cadder - Remark had posted 3/4" = 1/18xp, you took that for 3:4 which is not correct. It is 3/4"=1'-0", and there are (18 ) 3/4" in a foot, 12/.75=18.

[ReMark]

Thank you for pointing that out rkent. To make it clearer I went back and changed it to: 1/96xp is equivalent to 1/8"=1'-0" and so on. I hope that avoids any confusion I may have caused.

rkent,

 

Thanks for the information.

 

So then it'd be: 1 drawing unit to 18 paper units? (You need to know that information to add a scale to the VP scale list.)

[ReMark]

That scale should already be on the list if you were using imperial units. It is on my list in the copy of 2010 I'm running right now. And it is not listed as 1:18; it is listed just as I have typed it: 3/4"=1'-0". The same goes for all the other scales of this type such as 1/2"=1'-0", 1/4"=1'-0" and so on.

 

Could you please post your drawing? Thank you.

[The Mad Cadder]

Thanks. That's what I was using, - but it came out so small. (model space in the drawing is 1:1) I was hoping for a different result.
