4.2_Tracing Using Extensions

0:01 To wrap up our overview on using CAD linework as a reference base to draw on top of, let’s do the process one more time…this time using an extension.


0:13 The extension we’re going to use is called ‘1001 Bit Tools’.

0:17 Like the other extensions we’ve used so far, a download link has been provided in the ‘Extensions PDF’ in your exercise files folder.

0:27 This extension combines a number of useful tools together specific to architectural modeling.

0:33 For our needs, we’ll only focus on one of the tools for this lesson.

0:40 Once installed you can either show the entire toolbar…

0:47 or, since we’re only using one tool from it, we can customize the toolbar...

0:57 and find this icon that looks like a zigzag wall...and drop that onto our default toolbar for easy access.

1:12 As you can see, I’m starting again with a blank version of my ‘Method-3’ SketchUp file from the previous lesson.

1:20 With this extension method, I’m going to bypass tracing all the walls in order to extrude them...

1:28 as this extension will extrude the walls automatically as I trace them.

1:37 After launching the walls tool and I’m prompted to enter some settings.

1:42 After launching the walls tool and I’m prompted to enter some settings.

1:42 For wall width, I’ll start with the interior walls which are 4 inches.

1:48 Then like before, they are 9 feet for the height.

1:53 There are some other settings here but I’ll ignore them for now and click ‘Build Wall’.

2:01 I can then just choose a starting point of a wall on the CAD plan and start following it from corner to corner.

2:15 When you get to the end of a wall, just hit enter to finish the command...

2:24 and select the tool again to start another wall.

2:29 For this lesson, I’m not going to draft all the walls now since the process is the same for the rest of them.

2:42 As you can see, our walls are all at the right width and height as well as nicely grouped so we can eventually assign them to their own layer later.

3:03 Feel free to play around with some of the other drawing and modeling tools that comes with this extension.

3:09 For example, check out this handy tool that cuts openings into walls – even once they’re grouped

3:19 So with that, we’ve reached the end of our CAD to SketchUp learning track.

3:25 Whichever method you choose to use when dealing with CAD files,

3:29 you should now be well prepared to both anticipate potential problems in advance in CAD...

3:36 as well as know how to fix them after the fact once in SketchUp.
