Skill Level Beginner
In this lesson, we are going to be creating glass panels of inside or outside railings. Traditionally, I would have you go create a family and load into the model and there is a ballister panel family but we'll be avoiding this, since these families are just too difficult to manipulate. We are going to create a family however. It's called an in place family. The objective of this lesson is to create glass extrusions that are customed to the stairs we're working on. We need to add reference plains and hosted extrusions to accomplish this task. Think I've started, find the riven model called panels and stringers.
And in the project browsers, on the floor plans, go to level two. The first thing I'd like to do is create a reference plane and give it a name. What this does is this gives us a plane to model our glass panel in. What if it doesn't know where we want it. It doesn't understand we want a panel here as opposed to way back here. We need to establish a reference plane to determine that point. To do so, go to the architecture tab and clickk on the Ref Plain, all the way over on the Work Plain panel. Zoom in on the stairs and find the mid point by typing S M, once you see the Magenta triangle appear and the mid point texts show up, pick that point.
Scroll out, and just pick another random point off to the right, and hit Escape. Select this reference plane, and let's give it a name, let's give call it "South Stairs." Let's repeat the same procedure up top. Click the Ref Plane button, and select the midpoint by typing sm. Sm, again, means snap mid. So if we pull out to this point we can pick another point for our reference plane, and hit Escape. Let's not forget to label it.
Select this reference plane. Let's give it a name of north stair, (audio playing) and then apply. With the reference plans instead its time to actually create the extrusion to do that lets click to the south elevation that's this little hat right here. If you go onto plan hover over it and double-click on it you find it opens up the elevation. If it is just go ahead and select this box and move it up so you can see the entire thing. This box is called a crap region.
The next step is to physically model the extrusion. So I'm going to zoom in on my area. What we're going to do is we're going to put a panel, right here in this little parameter. To do that we're going to create an in place family. If you go to the Architecture tab, you'll see Component, the button we've been using. If you click the drop down here you see instead of placing your component we can model one in place. Let's come down and find the best category that we can and its probably going to be railings if you go into railing its probably going to be supports.
Click Okay. The name of this panel is going to be south, glass, panel. Click okay. Now the next most important thing is to use that reference plane we made earlier. To do that, click the Set button on the Work Plane panel. Hit the drop down, let's go all the way down the south stairs reference plain, click Okay. Now, we've established a work plane. What we're going to do, is start the extrusion. On the Create tab, click the Extrusion button, on the Draw panel, let's click the Pick Lines button, let's set our offset to one inch.
We're going to offset this panel N, one inch from our perimeter, click this, click the top rail, click this rail, you can't click this rail cause it's slightly skewed but that's Okay. Click the bottom rail. Click the bottom stringer and then hit escape. Let's clean this up, you can click on the Trim button or you can type TR for trim, either way you like it. I'm going to click the button.
Remember, when you clean up the corners, pick the lines that you want to keep. It looks pretty clean. Sometimes, though, it's a good idea to just make sure you're trimmed. You'll be able to tell because you'll select one and if you hover over the next one, if it's actually trimmed it won't highlight. So, we're good here. Hit escape a couple times. Next thing I want to do is draw a line in one inch from here. Actually, there's going to be two inches from the outside face.
So click the Line button and come down to the stringer here, and zoom out a little bit until you see that it says two inches. Once it says two inches, pick that point, and draw a line straight up. That might take a little practice. Go to Trim and trim out this area. (audio playing) Excellent. We're getting there. The next step is to look at the properties of your panel cause right now, it's just a box. The first thing we look at is the extrusion end. Pretty deep for a glass panel.
Let's type in one eighth of an inch, the extrusion start however, is going to be negative one eighth of an inch. Why are we doing this? Well because we're straddling this reference plane, we want this glass panel to be centered, so therefore it's going to go beyond this one eighth and it's going to come towards this one eighth, giving us a quarter inch overall. Next important thing is what makes glass glass for the material click inside where it says by category and select a smaller biller button. This will bring up our materials dialog.
On the material browser type in glass select a tab, just glass choice and hit Okay. If you go to a 3D view you should be able to see your panel. It's a little bit ghosted because we're not quite done with the family but that's okay. Go back down to level two. Go back down to the south stair elevation. The next thing that we need to do is draw another reference plane here, because we're going to put an extrusion on the radial part.
So, if you go to the create tab, click on the reference plane and let's just draw a reference plane, snapped to the top of the stringer. Hit Escape a couple times. Select the reference plane. Let's call it top of landing, and hit Apply. Now, go to level two. We're going to create another extrusion coming at us this time. To do that, go to the Create tab, click Extrusion.
This time I want you to pick Start and Raise Art. Zoom into the top of this stringer. On the Draw panel, click the Pick Lines button. Let's give it an offset of one inch. I want to come to the outside face of the stringer and offset that line in one inch. Now, I'd like to offset it one eighth of an inch. Offset the same line, out an eighth, and in and eighth, and hit Escape.
Go ahead and delete that line. The next thing I want to do is draw a line to cut this off. Draw a line, in approximately one inch parallel to the other line, trim it. Come all the way to the other side and do the same thing. Now, the extrusion start can be 0, and the extrusion end, let's make it two foot six, and hit Apply.
Click Finish. Now what I want to do is go to the East stair elevation, let's make sure our panel is all the way up to the bottom, and let's bring it down approximately an inch. Go to a 3D view to verify it, the last think I want to do is creating extrusion on the other side of the stairs, so under elevations let's go to north stair elevation, let's repeat the same procedure on the Create tab, click the Set button. For the plane, let's go to north stair, and click Okay. The same thing we did before, let's create an extrusion that straddles the reference plane.
On the Create tab, click Extrusion. On the Draw panel, click the Pick Lines button. Let's give it an offset of one inch. We're going to offset all these line in one inch. This one is a little easier than the other set. Click the Trim button.
Let's Trim out our edges. Even the edges that seem Trimmed, just make sure you have them Trimmed. Now, for the Properties. Extrusion end will be one eighth inch, extrusion start will be negative one eighth inch. The material will be glass. Click Apply. Click Finish Edit mode.
Now click on Finish model. Go to 3D View, and our glass panel is all set. Not too shabby. We just took a very difficult task and blew it out pretty quickly. Although it may seem a bit tedious, this is the way to go. We were able to establish the elevations we needed, the reference plans we needed
