Right.
So now we're going to add some dimensions onto this drawing.
We can see we've got the dimensions on our marker.
I'm not going to add all these.
I'm just going to add on this one.
I'm just going to add the two main dimensions.
In fact, I'm going to have the main dimensions, some a few dimensions around the outside and you'll
see why later.
But let's go over that again.
We've done it in the core module.
Let's put it into practice.
So the dimensions I want here are just straight dimensions, linear dimensions.
Okay, now I'm going to add one.
I'm going to put it on there like that.
And you can see we've we can't see it.
We can't see the text.
We can't see the arrows.
We need to edit our style.
So I'm going to do this the same height as the text we did down here.
The arrow size will be 2.5.
Okay.
I want them as close filled arrows at 2.5 and extension.
I'm going to change these to 2.5.
The text height to 2.5 offset 2.5.
Okay, I'm going to change.
I'm going to be able to move the text with no leader and precision.
I'm just going to have it set to zero.
So this is going to give us a dimension in millimeters.
I'm going to select the dimension right click, go to dimension style, save as new style.
And I'm just going to call this building style.
Okay.
I'm going to okay that.
Now up in annotation under the dimensions in the pull down Styles menu, we have our building style.
So by selecting that here, we set it as the current style.
But I want you to notice something here, something that's happened.
When we speak about model space and paper space, we know that in model space this is actual size.
So this is 20,000 long.
It's drawn actual size in paper space.
Our title block is drawn actual size.
So if I was to measure a distance here, it's 2.85.
But when we put a dimension on, even though we added our dimension in paper space, because we we're
clicking these points, these corners of the building, AutoCAD is intelligent enough to know that we
want the dimension on the building and what AutoCAD does.
It will look at the scale of our viewport and where we've clicked and it will do the calculation to
work that out.
Okay.
Now I want to show you something that happens a lot and people don't really understand why it's happening
sometimes.
And I'm going, I'm just going to draw a rectangle here.
Okay.
So that's any size.
We don't know what size it is.
It's in model space because I did it in tiled model space.
If I put a dimension on
and I can, I don't have to change the height, but I can say under text it's 71 797 long.
Okay, So you don't have to follow this.
This is just something I want to show you.
If I go back to pose space, if I put a dimension on here now.
It's actually dimensioned it way too big.
It's 179759.
AutoCAD is it's it's adding a scale factor on here and it's it's not coming up with the correct dimension
and you can see people find this happening in AutoCAD because they haven't quite set the dimension up
correctly.
What you need to do to get around that, if you see that happening, if you go to the current dimension
style.
Okay.
And then modify.
And you want the primary units tab.
This is a scale factor.
Okay.
So this is it's like how it's scaling it up.
Okay, now we'll say apply to layout dimensions only.
Just set that to one.
Okay.
And if you have a scale factor two one, then that will solve your problems.
If you find that happening where it's coming out with weird figures, that's the issue.
And you'll see now it's coming out of the correct dimension.
So if you put a dimension on and I would say when you create a new dimension, like we could always
change that scale factor to one, because if you're doing your dimensions in paper space and that's
how you want it set, and now when we add these dimensions as well, they all come out in the correct,
in the correct way and we'll put some on.
Let's add a couple for these windows.
Okay?
And let's add that.
And then I'm going to put.
Yeah, why not?
So that's how you dimension a drawing.
It's another thing.
It can seem a bit complicated, especially that scale factor.
But I would say you don't need to 100% understand what's going on.
Just that.
Just change the scale factor to one.
Okay.
And that will, um, if you're getting any weird behavior, like I said, AutoCAD does the calculation
with the scales and the units and sometimes it gets confused what it's doing.
And again you can use property painter on these.
So if this let's say you had a dimension, the standard, the default dimension have been changed and
you created one and it doesn't look right, you can just do a match properties from dimension to dimension.
And that's dimensions.
