Method 2 - Optimizing CAD File Prior to SketchUp
Freeze/Purge Non-Importable Items

3.2_Freeze:Purge Non-Importable Items

0:02 Let’s start by checking our list that we created in the previous lesson.

0:09 The first thing I identified was to delete or purge anything we know we don’t want or need for modeling in SketchUp.

0:17 This will help in anticipation of our next step, reducing and consolidating layers as well.

0:23 Before going on, be sure to save a copy of this file so that we can go back to the original if we need to retrieve anything that we accidentally deleted later.

0:35 I’ll save a copy with the name ‘Arch_FP01_Cleaned’.

0:41 You may also name it something like ‘_for SketchUp’ noting that this file is destined to become a 3D model and will likely contain less information that your original plan.

0:54 Also note that I’ve provided you a finished, cleaned up floorplan as well so feel free to follow along with these steps as we go...

1:02 or just sit back and take some mental notes as you’ll have an optimized plan ready for SketchUp in later lessons when the time comes.

1:12 There are two trains of thought on how to approach this first step.

1:15 One it is to delete data we don’t need directly from this drawing with the assumption that we’ll be importing this file into SketchUp later.

1:26 The other option is to just freeze the data for now knowing that that we’ll be copying and pasting just the relevant information that we want into a new clean drawing for importing.

1:39 Different drawings might require a different approach but for us, let’s play it safe and plan eventually to move only the relevant information into a new clean file...

1:49 file in order to make sure we’re not bringing over frozen or hidden objects or any other settings that might cause us problems later.

1:59 I like to use the ‘LAYFRZ’ command to freeze linework we don’t want.

2:06 With the command active, just click on all the text…electrical stuff…dimensions…arrows…hatches…and anything else that appears to be stray lines.

2:28 We have to be careful here as there may be linework that’s on a layer that we DO want to keep on.

2:35 If that’s the case, like in the bottom left corner, then simply selecting and deleting what you don’t want should be fine as well.

2:45 Also, there are some layers nested with blocks that won’t easily freeze.

2:55 In this case, we can copy a block off to the side...and then explode it.

3:05 Then try freezing the exploded linework again.

3:10 If you make a mistake and freeze something you meant to keep on…don’t worry, just undo it until you’re back to where you want to be and continue on again.

3:24 So let’s pause here for a second before moving on and see how our plan looks.

3:33 It’s looking much better already and we just started our cleanup effort.

3:37 So let’s move on to the next lesson where we’ll try to reduce our layers down to a manageable amount.
