I did my almost all of my graduation project in the units of engineering, so 1ft. was 1.0 and 1ft 6in. was 1.5.  Is there anyway i can scale my project to architectual without redrawing the whole thing?

The only time you would ever need to scale a DWG would be when you're converting from Metric to Standard (or vice versa). Changing your units (engineering, architectural, decimal, etc) doesn't affect the length of an object.

But to answer your question: Yes, you can scale any 1 or all objects in your entire drawing without having to redraw anything by using the SCALE command.

Since you're still a student, I highly recommend you use the F1 Key as frequently as possible. AutoCAD has an impeccable HELP system that you should use daily. If not, then you're robbing yourself of valuable information.

Good Luck!!!

Why can't you just choose "architectural" units?

i drew the drawing in engineering units. changing the units doesnt translate a unit of 1.0 to 1ft. its not the same distance. changing it to architectural wouldnt do anything. im looking for a way to scale it

As previously mentioned, the SCALE command will do what you need.

You can also select ALL the objects you want to SCALE, pick a base grip, and depress the spacebar 3-times.

Good Luck!!

By the way, UNITS in AutoCAD are just that - units. In modelspace, you are ALWAYS drawing 1 UNIT = 1 UNIT. The only place Engineering or Architectural units come into play are when you're entering the units or showing measurements. But 1 Architectural Foot is equal to 1 Engineering Foot. It always has been, and always will be.

So again, as previously mentioned "Changing your units (engineering, architectural, decimal, etc) doesn't affect the length of an object."

I don't see how changing from engineering units to architectural units is going to change the length of any of your lines.

its fine, i did the project. it does change it though. try it out in AutoCAD. draw a line of 10. now, change the units to architectural. now draw a line of 10'. the lengths are different.

i just figured it out though. you just scale from it by 12. BECAUSE 12X10.0 in engineering = 10ft. in architectural.

That's because when you first drew your object of 10, it was 10 units. But when you drew your 2nd object of 10', you actually set the FT.

Try this out: Draw a line of 10, then WITHOUT changing to Architectural, draw a 2nd object of 10'. They too are different, because you specified 2 different lengths.

Here, read this tip: http://www.cadforum.cz/cadforum_en/how-to-convert-a-drawing-from-inches-to-centimeters-tip7103

Note, when scaling by 12, you scaled from INCHES to FEET. You did not change from Engineering to Architectural.
