Clarification on ACAD

04/20/2012 8:12 AM

Colleagues,

Please help me set different scale for horizontal and vertical axis in ACAD 2012.

To explain, in ACAD, normally the horizontal and vertical axis have the same scale. That means, from 0,0, if grid is 1:1000, horizontally moving by 3000 units would show 3000. Likewise moving vertically by 3000 units would show 3000.

I am working on preparing a sprinkler discharge graph for fire protection system, where the building area is measured in 100's of sq.ft, ie the y-axis while the water discharge is measured in 0.01 gpm/sq.ft.

So if I go horizontally by 5 units and vertically by 5 units, the coordinate of the point should show 0.05 gpm/sq.ft horizontally and 500 sq.ft vertically.

If i go additionally another 5 units horizontally and 4 units vertically, the coordinate of the point should show 0.1 gpm/sq.ft horizontally ((5+5)*0.01) and 900 sq.ft. ((5+4)*100) vertically.

Setting any one unit, makes the other unit very small or very big. How to set independent units for x and y axis?

Soliciting your advise and support.

Autodesk has tons of on-line support. If you have a registered copy of AutoCad, you can get personalized help.

Autodesk - AutoCAD Civil 3D Services & Support - Support

I don't have a clue, myself and my AutoCad is 2006 LT.

Try altering your dimensions in a new layer.

Excellent! Create 2 dimension styles, one with a DIMSCALE of 1 and one with a DIMSCALE of 3 (or is it 1/3?) This will give you both of your wanted scales without distorting your drawing.

Shall we assume you are asking about AutoCAD? I've never seen an option for setting different values for X axis versus Y axis on any CAD program -- nor would I expect to.

Graphs are usually created with a spreadsheet, MathCAD-type programs, or dedicated graphing packages.

Free spreadsheets include LibreOffice/OpenOffice, GoogleDocs, and more.

Can you do something with scaling when plotting to get the same result?

I'm barely able to change layers, myself.

There may be another easier solution, but here is what comes to mind...

1. Draw what you want at 1:1 (H:V).

2. Create a block of the graph.

2a. select the whole thing.

2b. ctrl-c

2c. ctrl-shift-v

3. select the block and change the scale for the Y axis in the properties.

AutoCAD LT = Settings>Drawing>Limits

Then on the comand = Lower Left Corner 0.0000,0.0000 enter,

Then on the comand = Upper Right Corner 0.0000,0.0000 enter.

You can use the grid command to set different snap intervals in X & Y.

Dear colleagues,

Tried the suggestion of Harryburt and it worked.

Executed as follows:

1. Find the point 0,0 in the drawing.

2. Made the grid with spacing of 200.

3. Made a dimscale new, titled the dimscale suitably for y axis and provided scale factor of 1.

4. Made another new dimscale, titled the dimscale suitably for x axis and provide scale of 0.05/1000 = 0.00005.

5. Drew the graph.

6. If any point is selected and try to check the x-axis coordinate, the coordinate gets indicated.

7. Correspondingly if the y axis dimscale is selected, the y-axis coordinate gets indicated.

Thanks Team. Also if any more ideas, please suggest.
