Parking Plot

Recommended Posts

HI,

If anyone can help me,I am begginer and I am trying to draw some parking plot using autocad 2015.I am interested about units and viewing that parking.Space of parking s about 60000 m2 .I am asking what unit should I use,if I use meters it will be very big object in autocad ,and when I zoomed out I cant see some small drawings.

exp: there is about 30 000 parking plots in 60 000 meter long place,when I zoomed out I just see some lines.

HELP HELP:)

Don't worry about the drawing being big in AutoCAD you can go as big as you need. Type UNITS and you can amend the units of your drawing to your local requirements. If you zoom out and can't go any further out type RE which runs the regenerate command and you'll be able to zoom out further.

You do realize that 60,000 meters is 60 kilometers, right?

 

No matter what units you use, you must always draw your modelspace objects FULL SIZE. Never scale your drawing in modelspace. All scaling of views is done in a paperspace layout.

 

is 60 000 m equal to 60 or 60,000 m? I am guessing 60 meters since 60,000 meters is about the distance between a couple of medium sized cities. Proper punctuation does help.

 

If your units are meters, your parking lot will be 60 meters long.

 

If your units are millimeters, your parking lot will be 60,000 millimeters long, which is exactly the same size, only the units are smaller.

 

Which units are standard for your company to draw civil type drawings in? Use their standard units.

 

Don't worry about the zooming. It is just the way it is. If you draw a shoe full size in detail, and zoom out to view the whole shoe, you will not be able to distinguish the stitching.

 

Zoom to a level that is comfortable to view and draw what you are doing at the moment. You don't have to draw the parking division lines with the entire lot displayed on the screen.

Actually what I said above is not true at all, it just looks like it is true. It is good enough, that we act as if it is true. I didn't want to confuse a beginner any more than I already do by accident.

 

What actually happens is, AutoCad never changes the size of THE UNIT. The dimensions and measurements the drafter applies to the drawing are programmatically scaled and re-labeled to show the expected textual outcome based on what the drafter has named THE UNIT.

 

One can see this if we have two drawings, each with a square drawn in it. In one drawing, the units are Meters, and the square is drawn at 60 meters sq. In the other drawing, the units are millimeters, and the square is drawn at 60,000 mm sq. In the real world these two squares are exactly the same size.

 

Now, we take the drawing of the square drawn in millimeters and copyclip it, then paste it next to the square drawn in meters. There are two sub-parameters in the command -dwgunits which, if not properly set, will cause the above mentioned programmatic data and textual manipulation to not happen, and the newly inserted square will not be scaled by -1000. It will be inserted at 60,000 units sq. In this case, since the units in the current drawing are defined as meters it only takes 60 of them to a side to draw the size of square we need, so the one at 60,000 units is way out of whack.

 

The pasted drawing of the square drawn in millimeters will be 1000 times larger than its neighbor drawn in meters. This occurs, because Autocad pasted the drawing in using THE UNIT, not having been asked to fix things before doing so.

 

The two sub-parameters under the -dwgunits command that I referred to above are;

 

Scale objects from other drawings upon insert? [Yes/No] : N

 

Match INSUNITS to drawing units? [Yes/No] : N

 

Since I changed both sub-parameters values to N(o) from the default of Y(es), the inserted square gets to prove that AutoCad never changes the size of THE UNIT

 

The way AutoCad and ANY other drafting program is written, the program never has to deal with anything weird in its main operation. It only has to set a scale factor internally in order to be able to display and calculate all the dimensions properly when you ask it to label or measure something.

 

Having been a programmer for 23 years in another life, I cannot imagine the size and complication level of a program that had to deal with a few dozen units of measurement that are ALL managed by code, at different sizes of units.

 

Since Autocad modelspace is only a coordinate matrix where the drafter, usually unknowingly, is only naming vectors from one coordinate to another, I think any approach other than the absolute UNIT would be nearly impossible. This is why you cannot EVER mix units in one drawing. Well, there are the "Alternate Units" available in the dimension style editor, but that is just more scale and textual label manipulation. It's not changing any units, just displaying the answer to a math problem.

This ignorant question that I asked arose from me forgetting that some parts of the world and or some disciplines use a comma for a decimal separator, and that the OP put a space there.

m2 would mean area. 60,000m2 equates to about 15acres - a pretty heft car park!

 

 

External detailing, site layouts, etc. in the UK tend to be drawn in meters. Parking spaces themselves are usually 2.4x5m, which is 12m2.

At 5m long you obviously dont have tradies with brand new Nissan Tritons these type of vehicles are just so big in every direction. :D
Yeah, a 6 wheel Ford F450 box truck ain't parkin' there either. As a matter of fact, my daily driver, a 1999 Chevy Suburban is 18'-3 1/2" long. What's that in Euros, er ah, I mean meters, about 5.6m and change,right?

 

You know, 5.4m is about the size of a supermarket parking space hereabouts. I stick out close to a foot.

Well, the exponential interpretation is a given, but it doesn't help when the OP puts either nothing or a space where the comma or decimal point should be.

60000 m2, 60 000 meters long, and 30 000 parking spots were included in the same paragraph. You want to tell me how big it is again? :lol: I still have no idea.:lol:

Even the Australian parking standards at 5.4m/5.5m only cater for the B85 design vehicle from memory and which hasn't been updated for a fair while.

Your correct Organic but as you know here in AUS the cars are getting smaller, the developers would love smaller spaces. Ps I park this in bays that have a overhang its 6.0m, center of the road gets a bit difficult at times.

A quick look at the Nissan UK website suggests they're too big to even be on sale over here!

 

 

We had an Australian friend of the family come to visit us last summer who several times expressed shock at how small cars over here are, even given how much bigger they're starting to be (noticeable so, IMHO, in the last five to ten years).
