I recently purchased a Google SketchUp Pro license. A major difference between the free version of SketchUp and the Pro version is that LayOut 2 and Style Builder are included in the Pro version. Style Builder is an application that allows you to create your own drawing styles. I haven’t used it, and its not likely I will in the near future. Style Builder seems most suited to architects and marketing types.
LayOut 2 is another story. I have used it on a couple of projects to create shop drawings from my SketchUp models. LayOut 2 is a presentation package that can be used stand alone or tightly coupled with SketchUp. Using it stand alone you have many of the 2D drawing, lettering, labeling and dimensioning features of SketchUp. To create shop drawings I use it tightly coupled with SketchUp. In this two part post I will describe how to setup LayOut 2 for this purpose and I will walk us through how I created my own custom template for shop drawings. In subsequent posts I will demonstrate how to create the shop drawings themselves.
See the figure above left, which shows a completed shop drawing cover sheet. The template we will create will look like this one. Use this for reference as we proceed. Follow along with me on your own system as we create my custom template. First we need to setup LayOut 2. Open LayOut 2 to a blank page using the File/New menu. In the Window menu select the Pages, Layers, SketchUp Model and Text Style dialog boxes. Click on the picture at right to see an enlargement showing these selections. I use these dialog boxes frequently and leave them open all the time. Notice in the upper right hand corner that these dialog boxes are placed in a Default Tray. LayOut 2 allows you to create a number of trays with different dialog boxes, sort of like a pallet. If you wish you could go to Window/New Tray and open a tray called Tray 1 by default. You can label it anything you want. Check all the dialog boxes that you didn’t include in the Default Tray and choose Add. Now you have two trays that are selectable from tabs along the bottom; the Default Tray contains the dialog boxes you frequently use and Tray 1 has the remaining dialog boxes you seldom use. This may be a handy way to work, but it is all about personal preference. I don’t bother with anything besides the Default Tray. If I want another dialog box I just use the Window menu and temporarily open it in the Default Tray.
To define the paper size and orientation use the File/Document Setup menu. This command opens the Document Setup dialog box. and we choose the Paper selection. In the Paper section choose Letter (8.5 in x 11 in) from the drop down box and the Landscape radio button. The Print Paper Color check box will remain unchecked.
Check the Margins check box, and for Left, Right, Top and Bottom use 1/2”, 1/2”, 3/4” and 1 1/2” respectively. Leave the Print Margin Lines check box unchecked. The Margins Color is Light Gray. In the Rendering section we will select High for both Edit Quality and Output Quality, a personal preference choice. Your dialog box should look as that at left.
Next we will set up a grid which will aid us in placing SketchUp model scenes on our shop drawings. Using the File/Document Setup menu open the Document Setup dialog box. Select the Grid item. Check the Show Grid check box because we want the grid to show on our shop drawing pages as we create them. You can choose between a grid constructed of lines or points; personal preference again, but I suggest we choose the Lines radio button.
The grid can have major and minor grid lines with different colors. I am accustomed to one inch major grid lines with eight sub-divisions for the minor grid lines. That provides a 1/8” grid which is appropriate for furniture design in US customary units. If we were drawing in the metric system we might choose one centimeter for the major grid and five for the number of sub-divisions. Check both the Major Grid and Minor Grid check boxes, and enter 1” for the Major Grid and 8 Subdivisions for the Minor Grid. The colors are purely personal choice. I suggest Light Sky Blue for the Major Grid and Light Gray for the Minor Grid. To select a color click on the Color box and the Colors dialog box opens in the Default Tray. There are a number of options for choosing a color. You may use the color wheel, input a color in either RGB (Red, Green, Blue) or HSB (Hue, Saturation, Brightness), choose a gray or color from sliding scales or choose a color from a List. We will sue the latter. After choosing a color close the Colors dialog box to get back to our original dialog box choices for the Default Tray.
We will eventually choose the Clip grid to page margins check box, but for now leave it unchecked. Why we do this will become clear later. Leave the Print Grid and Draw grid check boxes unchecked because we don’t want the grid printed when we print our shop drawings, and we don’t want the grid obscuring our drawing while creating it. Click close to save these setup choices. Our blank page is now a sheet of grid paper.
Now that we have grid paper to assist us in placing objects, we need to instruct LayOut 2 to use it. Using the Arrange menu click the bottom two menu items until they read Object Snap Off and Grid Snap On. We are now ready to begin drawing our custom template. Use the “Lines” tool (pencil) to draw a rectangle whose sides are 3/4” in from the top and 1/2” in from the sides and bottom. Note we using the “Lines” tool, not the “Rectangle” tool, and we draw individual (separate) lines to create this box. To make each line separate, after drawing each line press the Esc key. If we didn’t do this, or we were to use the “Rectangle” tool, we would cover my grid with a white face (though I could use the Shape Style dialog box to inhibit this) and the lines would be connected which would cause a problem later when rounding the lower corners.
Draw a horizontal line 1 1/2” up from the bottom and stopping 1/2” from each side thereby terminating on the sides of the box we just completed. This creates a box 1” high and 10” long. We now draw a vertical line to sub-divide this box into a 1” by 4” box on the left and a 1” by 6” box on the right. We need one more straight vertical line to complete our boxes. This one will be parallel to the left edge, 1/2” to its right and extend from the top horizontal line to the first horizontal line that is 1 1/2” up from the bottom edge. At this point our rough template should look exactly as the picture above left.
To complete the boxes that outline our template we will use the “Arcs” tool to round the bottom two corners. The arc will be one quarter of a circle with a radius of 1/4” (2 grids). Refer to the picture at left. Using the “Arcs” tool click on a grid center point (Point 1). Next click on the 90 degree radius point (Point 2). Lastly click on the second 90 degree radius point (Point 2). Now we have a rounded corner, but still have the original square corners. To fix this we simply select each line, one at a time, with the “Select” tool and move the endpoints back 1/4” (two grid points). After selecting a line with the “Select” tool, hover over an end point until the cursor turns to two opposing arrows. Click and drag the endpoint back 1/4” with the assist of grid snapping. Be careful not to move the entire line but just the endpoints.
Now we will place my Swamp Road Wood Works logo (click the hyperlink to download it). With the File/Insert menu open the Open dialog box and locate the logo file you just downloaded. Highlighting it click on Open. The logo now appears in the center of the page and is selected, indicated by the blue bounding box. The logo is too big and in the wrong position, but correcting these problems is easy. Hold the cursor over the logo until you see the cursor change to four opposing arrows. Click and drag the logo and place the upper left corner where it should be (refer to the picture at right below). Next hover with the cursor over the lower right hand corner until the cursor turns to two opposing arrows on a diagonal. Click and drag the corner, but while doing this hold the Shift key down as well. This forces the scaling to be uniform. Place this corner where it belongs. You may need to repeat moving the corners until you get the optimum placement and size. Be sure to use the Shift key to maintain the aspect ratio. While the logo is still selected use the Arrange/Send to Back menu command to place the logo behind the lines we have drawn. This is to ensure the logo doesn’t obscure any of the lines.
We placed the logo as far to the left in the 1” x 4” box as possible and made it use all of the 1” vertical space. This leaves an area to the right where we can place my contact information. With the “Text” tool, click on the upper right hand corner of the logo and drag to the lower right hand corner of the 1” x 4” box. In the Text Style dialog box located in the Default Tray, choose Verdana Regular 8pt text. Now type my address and contact information as follows:
Joseph P. Zeh
325 West Street
Worthington, MA 01098
Getting the spacing right may require tricks like placing a blank line before may name to create a little spacing at the top.
So far we have had one page titled Page 1 and one layer called Default. They are shown in the Pages dialog box and Layers dialog box in the Default Tray. We are now going to add a layer called Logo & Outline. First add a layer by clicking the + sign in the Layers dialog box. A new layer is added call Layer 2, and it is selected indicated by the pencil to the left and the blue shading. Right click on Layer 2 and choose Rename. Type Logo & Outline and press Enter. With the Edit/Select All command select all the objects drawn so far. Note this outlines all objects in blue. Right click on any object and choose Move to Current Layer. This places all objects on the Logo & Outline layer.
Everything we have drawn so far we will want to appear on every page of our shop drawings. We will never change what we have drawn so far unless my logo changes, I move, get a different telephone number or change my email address. These are all unlikely to happen in any foreseeable future – I hope. To protect this information from change and to force it to appear on every page of the shop drawing we will make it visible, locked and apply to all pages. We do this with the three little icons to the right of the layers name. Click until the little eye is dark (not grayed out), the lock is locked and there are four sheets of paper in the last icon. The eye indicates the layer is visible on the selected page, the locked lock means it can’t be changed and the four sheets indicates it applies to all pages (of course we only have one right now). Now that this layer is locked it can no longer be selected so the selected layer has become the Default layer. To select the Logo & Outline layer again you must first unlock it. Locked layers cannot be selected (active).
Before we end Part 1 let me point out a few things. The page margins chosen were designed such that there is room along the top to punch three ring binder holes. The page will be placed in the binder in the portrait position. The grid only appears in the working area (actually it also appears in the little strip in the left, but that will be fixed in the next post). The grid is there to help place objects in the shop drawings by giving us something visual to snap to, but will not be printed with the shop drawings.
Stay tuned and we will complete the template in Creating A Custom Shop Drawing Template With LayOut 2 – Part 2 of 2. In subsequent posts I will demonstrate how to place the SketchUp drawings in the shop drawing pages for printing.
