Changing the linetype scale

“

- [Narrator] We're staying in our object layer properties .dwg file. And in the previous video we looked at object and layer properties and how they work within your AutoCAD drawings. Now you'll notice on this particular drawing that we do have some dashed linetypes. You'll notice on the hinge on the left, the horizontal lines are dashed. You'll also notice on the nut and bolt that the hidden thread line is also dashed on that arc as well. Now what you can do is you can make those dashes bigger and smaller. This would not affect a continuous linetype because it's continuous. But anything dashed or dashed and dotted can be affected by what is known as the linetype scale or LT scale. Now the linetype scale can be changed globally in the whole drawing, or like in the previous video you can do it individually for individual objects as well. So let's have a look at doing it globally first and the quickest way to do this is just type "LTSCALE" linetype scale, like that and you can see it comes up on the suggestion menu on the dynamic input. So just select "LTSCALE" and you'll see at the moment that our linetype scale factor is a default of one. It always is in any AutoCAD drawing, if it hasn't been changed. So that one is 100% or 1 and so on. So basically it means in its entirety at the moment, it's 100% sized. So what happens if I change that to 50% by changing the value to nought point five. If I press enter now, keep an eye on the dashed lines in the drawing. You'll notice that the dashes and the spaces become half their original size. So now our LT scale is at nought point five. So if I went to one of these lines here on the hinge, did a right click and went to properties. What would the LT scale say? It would say one. Now that's the individual linetype scale for that particular line in the drawing. So, why does that say one and yet the global LT scale is at nought point five? That's because they are two different values. So let's close the properties palette. Hit escape to deselect that line. And what I'm going to do is change the LT scale back to one. So LT scale, type it in like we did before. Press enter, and change that back to one in the box. And press enter again. And you can see the dashes return back to their original state. Now, let's select just one dashes line. I'm going to go for that one there again on the hinge. I'm going to right click and I'm going to go to properties. And now I'm going to change the linetype scale just for that individual line to, nought point five. Press enter to finish. Close the properties palette and hit escape. And can you see where the dashes and the spaces are now smaller than the original ones. So what we've done there is we've changed the individual linetype scale of one particular line. So if I go to this one here now and I right click and I go to properties you'll see that's at nought point five. If I close the properties palette, hit escape. Revisit the next line down and then right click and go go properties again. You'll see that is still set to one. So it is an individual linetype scale per object in this case. Not a global LT scale change, where you just type "LTSCALE" and change it globally within the drawing. So what I'll do quickly, is just hit escape select this line here and it's a right click, properties and we'll just change that back to one, and press enter so that it's back to it's original settings, close properties palette and hit escape there. So you can see that everything has been returned back to normal. So all the individual LT scales are set to one and the global LT scale is set to one also.
