Join Shaun Bryant for an in-depth discussion in this video Assigning properties by object or layer, part of Cert Prep: AutoCAD Certified Professional (2015).
- In some of the previous videos in this section, we've looked at changing object properties. But also, assigning properties to objects by the layer that they're on, by using the ByLayer setting. So, for example, if I select this dimension here, and go to the Properties panel here, on the Home tab on the ribbon, you'll see that everything is ByLayer for that particular dimension object. Now what I've done is I'm using the same drawing as before, so we've now got 7_Organizing_ASSIGNINGPROPS_Complete.
If you want to follow along do the usual drill, and use 7_Organizing_ASSIGNINGPROPS.dwg from your lynda.com exercise files. What we're going to look at now, is we're going to look at changing the settings to either ByLayer or we're going to change the object properties individually. So, I'm going to select the Polyline here that forms the outline of the object. So you can see at the moment the Color is ByLayer, the Layer is Object, and the Linetype is also ByLayer. What I'm going to do is I'm going to select the Polyline, like so, and you'll see the grips appear.
I'm going to go the Home tab on the ribbon, into the Properties panel here. Now you can see at the moment that the object layer is making that particular Polyline yellow. So if I change the object color individually, to say an orange, like so, it is still on the object layer. So if I just hit escape now and hover over that, you'll see that the Color is individual, the Layer is Object, and the Linetype is still ByLayer. So you can see there at the moment, that that particular Polyline has it's own individual color, which is that orange color.
If I click on it again, like so, and then go back up to the Properties here, and change that back to ByLayer there, you'll see it goes back to the yellow of the object layer that it's actually on in the AutoCAD drawing. Now the benefit you have is you can change any individual object that you want to. So if I now select this outline again, and this time what I might do is go to the Properties panel, and change the Linetype itself. So if I go Linetype now and change that to a hidden Linetype and hit escape there, you can see if I hover over it now, the Color is ByLayer, the yellow, the Layer is Object, and the Linetype now has it's own individual Linetype, which is HIDDEN.
So you can see that you can obviously individually change objects, and change their properties quite happily, including Linetype, Layer, and so on. I'm just going to select this back, go back to the Properties panel again, and change the Linetype back to ByLayer. So everything is now ByLayer on that particular object in the drawing. It's a useful tool, because sometimes you might want to change the linetype of individual objects, and not worry about the layer properties, so that they can be highlighted in a particular drawing.
Typical things are Lineweight, so I might select the outline again there, go back to the Properties, change the Lineweight to something, something like let's say 0.60 mm, like so. If I switch the Lineweight assignment on now, you can see that's much bolder, and stands out a lot more on the drawing. I then might toggle that Lineweight off, and it still looks normal, but what I can do there is if I hover over that now, click there, go back to the Properties, and you can see that that went up to 0.60 mm on that menu.
I can change that back by just scrolling up the list, and going back to ByLayer, and it will just use the Lineweight that is assigned in the Object layer. So that's how you can assign either property specific objects, or layer specific objects. So the objects might have their own individual color, lineweight, or linetype, or they follow the assigned layer driven color, lineweight and linetype. Again, practice, practice, practice, get ready for your professional certification exam.

Q: Is this certification available for AutoCAD for Mac users?
A: AutoCAD certification is on the Windows environment only. Currently Autodesk does not have plans for an AutoCAD for Mac certification.
Q: This course was updated on 02/01/2016. What changed?
A: We added four new videos to the "Certification: What Is It?" chapter. These tutorials cover Certiport, the online certification service that now offers a variety of Autodesk certifications.
