Best way to draw an abstract triangle background

Recommended Posts


I'm new with Vector drawing and rather new to AD.

What I'm trying to achieve:


What would be the best way to draw these triangles?

Steps and Problems encountered when drawing triangles with the pen tool in Polygon mode:

  • After each closed polygon a new curve layer is created, which makes it impossible to reuse a nodes and edges as part of another triangle
  • To use a triangle that is created through creating surrounding triangles, a polygon has to be drawn explicitely where each node is on top of others
  • To move nodes, all layers have to be selected and before moving a node I have to select join curves. This however is forgotten as soon as I select another layer

I've also tried using the triangle tool, but this doesn't make it easier, as I'll have to move more nodes around afterwards.

Maybe this is the way one has to deal with it, but I was hoping, someone could recommend a better workflow.

Thanks in advance.

Each vector shape, including triangular polygon ones, must have its own independent set of nodes -- nodes cannot be 'shared' by two different vector shapes, polygonal or otherwise. However two nodes of two different shapes can be coincident (have the same x & y coordinates). So for example, you can turn on Snapping (the magnet shaped icon on the main toolbar) & make sure this option is enabled:


Then, after drawing the first triangular shape using the Pen Tool in Polygon mode, it is a simple matter to draw the next one, snapping two of its nodes to two nodes of the first one & placing its third node at some other point. Continue that process for each new triangular shape until you have filled the background with them. It is also possible (& sometime more efficient) to duplicate a triangle in place over an existing one, switch to the Node Tool & drag one of its nodes out to form an adjacent triangle.


If you later need to adjust a vertex where the nodes of multiple triangles meet, you will have to first select all the triangle shapes sharing that vertex (usually easiest to do with the Move Tool) & with the Node Tool marquee select all those nodes & drag them to the desired position.


You do not have to (nor should you) use the "Join Curves" option at any point in this process.
