Create a Nuclear Symbol Icon
In the following tutorial you will learn how to create a simple nuclear symbol in Graphic for iPad.
For starters, you will learn how to setup a simple grid and how to easily center your main shapes using the commands from the Alignment pane. Next, you will learn how to slice your shapes and how to create the actual symbol.
Finally, you will learn how to create a gradient filled background and how to add subtle details for your final symbol.
From the Documents Browser, tap the plus button at the top-left corner of the Titlebar and choose the Grid document style.
Focus on the right side of the Titlebar and tap the Settings icon. Go to the Canvas pane, set the Width and Height to 600 px, select Pixels for the base unit, and make sure that the Pixel-Align Strokes feature is disabled. When this setting is enabled, stroked objects are offset slightly to ensure that the stroke is drawn aligned to the pixel grid which guarantees a crisp look.
Next, you need to setup the document grid. Switch to the Grid & Rulers pane. Make sure that the Snap to Grid feature is enabled and keep in mind that this is where you should come whenever you wish to enable or disable the grid or the Snap to Grid. Finally, open that Grid Settings pane, enter 10 px in both Spacing boxes and 0 lines in the Subdivisions box.
Focus on the Toolbar and notice that by default the Fill color is set to white while the Line color is set to black. Tap the Fill color well and set its color to R=28 G=28 B=28 and then tap the Line color well. Drag the Alpha slider to 0% and this will simply make your line invisible.
Pick the Ellipse Tool, move to yor canvas and create a 220 px circle - the grid and the Snap to Grid feature will ease your work.
Make sure that this shape stays selected and focus on the right side of the Titlebar. Simply tap that middle icon, focus on the Arrange pane and tap the Align Horizontal and Align Vertical buttons.
Set the Fill color to R=225 G=170 B=0 and make sure that the Ellipse Tool is still active. Create a 180 px circle and center it using the same Align Horizontal and Align Vertical buttons from the Arrange pane.
Set the Fill color to R=1 G=152 B=246 and make sure that the Ellipse Tool is still active. Create a 140 px circle and center it.
Set the Fill color to white (R=255 G=255 B=255) and make sure that the Ellipse Tool is still active. Create a 40 px circle and center it.
Set the Fill color to R=219 G=65 B=0 and make sure that the Ellipse Tool is still active. Create a 20 px circle and center it.
Pick the Path Selection Tool, focus on the newly opened pane and activate the Add to Selection mode. This tool will allow you to easily select or add new shapes to an existing selection. Focus on your canvas, select the blue and the white circles, move to the Combine pane and tap the Subtract button. In the end your blue shape should look like in the second image.
Set the Fill color to R=0 G=90 B=150, pick the Rectangle Tool, create a 120 x 100 px shape and place it exactly as shown in the first image.
Focus on the bottom side of this new rectangle and switch to the Path Selection Tool. Select the right anchor point and remove it by tapping the X button from the left side of your Titlebar. Select the other anchor point and drag it 60 px to the right. Once again, the grid and the Snap to Grid feature will come in handy. In the end your rectangle should turn into a simple triangle as shown in the second image.
Make sure that your triangle is still selected and switch to the Rotate Tool. Focus on your triangle and you should notice a little cross right in the center of the shape, that's the reference point. Simply tap on the bottom corner of your triangle and your reference point will snap as shown in the first image. Move to the toolpane, set the Angle to 120 degrees and then tap that Copy button twice.
Pick the Path Selection Tool, make sure that the Add to Selection mode is active and select your three triangles. Go to the Combine pane and simply tap that Make Compound Path button.
Select your compound path along with the other blue shape, focus on the Combine pane and tap the Intersect button.
Pick the Path Selection Tool and make sure that the Add to Selection mode is active. Select the blue shapes along with that tiny, orange circle, focus on the Combine pane and simply tap the Make Compound Path button. Make sure that your newly made compound path is selected, focus on the Toolbar and simply replace the existing Fill color with R=29 G=29 B=29.
Make sure that your compound path is still selected, focus on the right side of your Titlebar and tap the leftmost icon. Move to the Effects pane and simply check the box that stands for the existing Drop Shadow to activate it. Enter 1 in the Y box and 0 in the other two boxes and then tap the color well of this Drop Shadow. Set the color to white and drag the Alpha slider to 70%.
Return to the Effects panel and tap the cogwheel icon of that Drop Shadow effect to open the context menu. Go to Blend Mode, select Soft Light from that list and then tap that Done button.
Make sure that your compound path is still selected and keep focusing on the Effects pane. Activate the existing Inner Shadow and enter the attributes shown in the following image.
Select your yellow circle, focus on the Effects pane and tap the existing Stroke. Set the Width to 1 pt and the Alignment to Inside and then click the color well that stands for your Stroke. Replace the existing color with R=180 G=135 B=5 and make sure that the Alpha slider is set to 100%.
Select your dark circle and focus on the Effects pane. Activate the existing Drop Shadow and enter the attributes shown in the following image.
Using the Rectangle Tool (M), create a 600 px square and center it. Make sure that this new shape stays selected and focus on the Effects pane.
Tap the color well of the existing Fill, and then tap the Gradient Fill and the Radial buttons from the newly opened pane. Keep focusing on the gradient, set the Angle to 0 degrees and then move to the gradient sliders. Tap the left one and set its color to R=45 G=45 B=45 and then tap the right one and set its color to R=25 G=25 B=25.
Finally, go to the Arrange pane and drag the Order slider to the left to send your square in the back.
