Curved triangle

Oct 1, 2013 11:30 AM

Hello,

Can someone tell me how to create this highway shape with the lining inside in Illustrator? I have tried a bunch of functions and tools but I can't get them to be curved but with both sides looking natural.

Thanks in advance!

    sanniep,

     

    You can do it with Art Brushes:

     

    1) Create a triangle with a horizontal centre line and a height like the desired width,

    2) Add the white dotted line,

    3) Select both and in the brushes palette flyout select New Brush and then Art brush,

    4) Create paths with a Stroke Weight of 1pt and with each/all selected click the new Art Brush.

     

    With this, the shap will strech to fit the length of the path.

     

    A different Stroke Weight will give a proportially different width.

    Can be done with the Pen tool.

    sanniep,

     

    To create the triangle in 1), you may:

     

    1a) Pick the Polygon Tool (bundled with the Rectangle Tool (ClickHold until the options fly out)), set Sides to 3 and click Enter;

    1b) In the Transform palette insert  -30 degrees;

    1c) Set the value of W to something like the intended length and set the H value to the intended width.

     

    To add the dotted line in 2), you may:

     

    2a) Drag horizontally with the Line Tool, again to something like the intended length, then in the Stroke palette set the Stroke weight as desired and click Dashed Line and set Dash and gap as desired.

     

    To align 1) and 2), select both and in the Align palette click Horizontal Align Centre or Right (depending on whether you wish to have the dashes start at the end or not) and Vertical Align Center.

     

    You may swop direction if that suits you better.

    I tried the pen tool, I can create a triangle from a rectangle but I dont get it curved.

     

    In that case you will have to take some very basic lessons about the Pen tool.

     

    You may start with the online help.

    sanniep,

     

    I think I've got it using the warp->Arc tool!

     

    That will give you some limited options.

     

    If you procede from the triangular version of the road made according to 1) and 2) in, as specified in post #4 (your post #6 seems to apply that you have it), by creating the Art Brush according to 3), you may apply it to any curved path according to 4).

    Do the whole thing with the Pen tool.

    Picture 1.png

    Start off with the baseline of the triangle.

    Drag a vertical handle (constrained by holding down Shift) from each end and click somewhere vertically above each end.

    Average and join the top anchors to make the curved triangle.

    Copy one of the sides and paste it. Average it vertically. Change it to a dashed line with no fill and position it so that its top end coincides with the top of the triangle (left hand picture).

    Now direct select the top anchors only and drag (right hand picture).

    Here's another way.

     

    1. Draw a straight line with the Pen or Line tools
    2. Use the Width Tool to change the width at one of its ends
    3. In the Appearance panel add a new  stroke with a different color and in the Stroke panel reduce the width, make it with uniform profile, and dashed.
    4. Modify the shape of the path
