Limits in Model space

[DODGE]

Hi Guys

Can somebody tell me is there any point when you set up a new drawing in setting the drawing limits.

For example I am about to draw up a house plan at scale 1:100 which will be plotted on an A3 sheet. I envisage the floor plans will be on one A3 and the Elevations will be on another A3 sheet. Sections will go on another A3. I will have approx 6 paper sheets set up for this.

I plan to draw the whole lot in model space. Then move it around in paper space so each item is on a seperate sheet.

Is this the correct way to do it. If it is, then what is the point of having drawing limits in Model space?

The books I have, say it is good drafting practice to set up limits. But I can't see why:?

Also what is the point of setting up the grid display when half the time you draw right off the grid?

Any advice would be great.

Ta Dodge.

Grid is only for those who are brand new to autocad and need help figuring out how to draw. I only used it for about the first two weeks in class, and mostly because the teacher made us. So if you don't need it, don't use it.

 

Limits, I think, was created for plotting from model space. I would set the limits to something really big like 3600',2400' because if you don't, you'll most likely have a problem zooming in and out when drawing your floor plans and elevations and sections. Another tip that may or may not be helpful to you, when I do this, I usually draw a big rectangle (on a no-plot layer) around the separate drawings (plan, elevations, sections) and then draw text in the no-plot layer above the rectangles to lable the different drawing areas. I find that this helps to keep it more organized. But it would be best to do whatever makes you most comfortable.

 

And no, there isn't anything wrong with drawing it all in one sheet unless you are doing it for a big commercial project. In that case, you might wanna have separate drawings for that.

Good question(s). I suppose it depends on your application requirements. For me personally, no point in setting up either limits or grid. Interestingly though, I still have my default page set up at 0,0 - 16800,11880 and grid spacing at 400 i.e. A1 sheet @ 1:20. Habit I suppose.

G'Day Dodge....

 

Further to what pennylove and Groutie have said.....

 

Ignore drawing limits, or turn them off in your drawing template (filename.dwt). Also turn your grid off and don't use it. As for the method your intend to use for your drawings...bang on !!!

 

That is pretty well the standard way to do your drawings, but also have a layout for your plan as well as your sections.

Hi Al

How do you turn off drawing limits?

D

[Guest Alan Cullen]

Type command LIMITS...then type OFF....

[Lazer]

I have never used limits or grid myself but at colege we must tell students to set the limits as its part of the City & Guild course.

I tell them if they find a use for it ofter college then by all means set them, lol

[tzframpton]

well Limits are definitely good for super-noobs, just to gain the very basic concept when 1st learning how to draw a line in AutoCAD. most people know how to get their way around in Paint, but anything after that - pfft, SO much harder for true beginners.

 

what's funny, is that i've been on CAD so much and so long, Paint seems hard for me.... lol

Zoom all uses the limits as it's base to magnify the drawing + or -. Turning off limits turns off limit checking, which stops you drawing outside the limits.

So now I'm confused.

As my first question asked, whats the problem with drawing outside your limits in model space anyway?

When you go to paper space you can steer it all back into view on your selected paper size and scale.

So I ask again, whats the point of limits? Am I missing something?

The most common use of Limits is to control the extents of the grid. It also controls the extents of the Zoom > All command, unless you have drawn outside of your drawing limits. Then Zoom > All works the same as Zoom > Extents.

 

Limits are OFF by default. When Limits are turned ON, you are not allowed to draw outside of the specified limits. If you try, you will get a message at the command prompt that says "**Outside limits".

As others have said, it depends on the individual. Most people ignore limits once you start printing from viewports in paper space. It depends on your skill level. The other comments were not meant to confuse you, they were extra information to help you make an educated decision whether you want to use limits or not.

There is a large body of opinion that it a whistle. However, recent studies seem to suggest that it's actually a bell. I personally think it's customisable to be either. I suspect that an ex Microsoft employee was once employed during development, but was sacked when they found him roughing out a concept for an intrusive paper clip.

I am searching CT for threads on limits and grid and I found this thread very informative.

You have to go wayyyyy back into the last century and slow computers.

There was a time when you coould do a zoom or zoom all and go get a cup of coffee while you waited for your screen to regenerate and allow you to go back to work. Limits was a method of controlling what was regenerated (or displayed in the case of the grid). The idea was to avoid regeneration of the screen if possible if you wanted to get any work done. There was never anything "wrong" with drawing outside the limits. In fact setting the limits smaller than your drawing could be used to advantage.

 

I turned off grid (and soon thereafter the limits) in my second CAD class back in 1987.

I have only turned back on once a year because techniques defensable only in terms of history are required to be taught.

The technology limitations have long since been cleared.

 

Ahhhh, I just replied to a 5-yr old thread. I hate when that happens.

 

Ohhh noooooooooooooo, double post as well http://www.cadtutor.net/forum/showthread.php?62396-Gird-limits-model-space-area-drawing-scale the question had already been answered.

Khoshraven, please don't reply to old threads unless you have some new piece of information to add to the discussion. Replying to old threads just to say "this was informative" is not necessary.

OK. Still learning the netiquette:roll:.
