I know this might be a lame thing to TUT on but I have often wondered why Adobe fails to give us a traingle shape tool?
How to create a traingle fast and easy.
1. Open a new window and layout some guide lines like I have shown in the screen capture.
Make sure in the "VIEW MENU" you have "SNAP" Checked and below that "SNAP TO" make sure "GUIDES" is checked.
Sorry that the captures are not very clear but I haven't figured out how to shrink the file size down to load in here without loosing image quality.
Basicaly what you create with the guide lines is a 4 inch square or 4x4x4x4.
2. Select the Pen Tool and place a point where the lines intersect.
The circles show where to place the points. I started at the bottom left then to the top then to the bottom right and finished back at the bottom left.
3. Click on the Path Pallet and and then choose....Make Selection.
Then click OK. Next Go to "EDIT/FILL" and fill the triangle.
The result.
There are other ways of making a triangle but so far I find this to be the easiest. :}
HEY ADOBE!!!! Add a darn triangle tool will ya? [doh]
