Select the Shapes tab and then the Draw a rectangle using two corners button. If the Current layer is not paper then make it so. But first draw the paper that the sundial will be printed on. This way if I make a major error I can copy parts from the original. Normally I like to make a copy of the part of the drawing I work on and move it to a different area on the drawing. Thin may appear in the line weight box but it will not be applied to the lines unless it is selected. Select the Choose a line weight arrow and then select Thin. For multipleĥ 5 The Sundial Primer created by selections depress the Ctrl key while making selections. Draw a rectangle around all the lines so they are highlighted. The colours are okay but the lines are too wide Select the Select tab and then the Select objects button. Select the Move selected objects button and move the outline box to a new location. Draw a rectangle the line to highlight it. Select the Select tab and then the Select objects button. Figure 3: Layer Cleanup and Rescaling Move the line at the far right that represents the length of the gnomon close to the sundial.
The above discussion is illustrated in Figure 3. To fix this select the View tab and then the All button. To convert it back to millimetres select the 25.4 button and then OK. In DeltaCad the drawing is presently in inches and is 51 inches wide for example. What does this mean? In SONNE the sundial was designed in millimetres. The Set Drawing Scale will appear and the drawing scale is set at 1. Anything drawn from this point will be placed on the layer paper. Make a new layer called paper and select Make Current. The only layers left are default, L_1, L_2, L_3,Ĥ 4 The Sundial Primer DeltaCad and Your Cylinder (Shepherd s) Sundial created by Carl Sabanski L_4 and L_6. If the layer contains objects a warning will tell you that it cannot be deleted. Select each layer, except default, and then the Delete button. Some of these layers contain no information. 8 scale for Sun altitude 10 temporal hours 1 (?) protractor, arcs Figure 2: Cylinder Sundial Design in DeltaCad The DeltaCad Layer window shows the default layer as well as layer 0 and layers L_1 to L_10.

(full hours) 4 text 5 for times between full hours a.m. In SONNE the layers are identified as follows for a horizontal altitude sundial: 1 grid with dates 2 hour lines a.m. When SONNE generates the sundial design it places each selected line on a separate layer. Okay, now you are good to go!ģ 3 The Sundial Primer created by Select the View tab and then the Layer button. The cylinder can be of any material, plastic pipe for example, and there is no reason why the sundial cannot be larger or smaller. The dimensions of the sundial were decided during the SONNE design phase and it was a requirement that it fit on a heavy cardboard tube with an outer diameter of 56 millimetres and an inner diameter of 51 millimetres. The dxf file saved is now ready to be opened in DeltaCad. The sundial will show local apparent or sun time. This is the circumference of the cylinder. The following parameters were used for this design: Latitude: 50º North Longitude: 95º West Time Zone: 90º West Selected Year: 2007 Length of Gnomon: 75 mm Length of Scale for Months: 176 mm. Figure 1 shows the SONNE design just prior to being saved as a dxf file. You can then review the functions in more detail if you need to.
DELTACAD HELP MANUAL
You should have your DeltaCad manual available. They will not be discussed in detail here. You should have read DeltaCad and Your Sundial, which provides information on some important DeltaCad topics.
The information presented here is applicable to the design of any sundial. This presentation is only one approach and as you become familiar with DeltaCad you will learn techniques that you may prefer or that are better than those discussed here. A rotating gnomon will complete the sundial to make a working model. In fact, this will be a sundial that can be printed on card stock, cut out and then glued on to a heavy cardboard tube. In this document we will look at opening the dxf file in DeltaCad and modifying it so it can be used as a template for creating a real working sundial. 1 1 The Sundial Primer created by In the instruction set SONNE and Your Cylinder Shepherd s Sundial we went through the process of designing a cylinder sundial with SONNE and saving it as a dxf file.
