It’s best to add guide “curves” to be able to align your text on vertical lines, horizontal lines, curved lines, etc. To do this, select the line tool (or circle tool) and choose the type of guide curve you want (example: Centerline). Then draw the lines.
Sketch & Modify Text:
To type along the horizontal line, select the text tool (hollowed out A) and click along the horizontal line. Insert/type your text into the “text” box on the left hand side of the screen.
To customize your actual font (size, style, etc.) unclick the “use document font” box and click on the box right below that says “font…” Once there, you can choose your font, font style, height of font, etc.
If the text appears too small, off-centered, not bolded, etc., use the tools just underneath the text box to customize your text.
Transfer Text Vertically:
To transfer the text to the vertical line, start by selecting the horizontal line from the “curves” box on the left hand side and delete it. Then click on the vertical line. This should automatically transfer the text to your vertical line.
If you want your text to go vertically down the page and not just typed out on the line, select all the text in your text box. Once highlighted, select the “rotate” button just below the text box. Keep clicking rotate until your text is how you want it. If the characters are too close together (overlapped), edit the spacing between the text using the spacing tool.
Transfer Text to a Circle:
To type along the arc, delete the vertical line from the “curves” box, then select the arc. This will automatically transfer the text.
If the text is not on the section of the circle you want, use the “split entities” tool to divide the circle into sections. From there, you can select the exact section of the circle you want your text to appear on.
Use the font and spacing tools to adjust the font to how you want it.
