# How to draw in three-dimensional coordinate system in Inkscape?

I want to create a drawing using a three-dimensional coordinate system in Inkskape. I am trying to re-create a drawing similar to the image below:

Right now, I am make three arrows and attach them manually to each other. I am wondering whether there is a more standard way of doing that in Inkscape, i.e., creating a frame in Inkscape with all three axis connected at the centre to form one entity.

• It's not exactly clear what you're asking. Are you asking us to help you make a 3D co-ordinate system in InkScape, or simply draw the image that you've posted? – Paul Nov 28 '16 at 8:47
• I apologize for being unclear. I needed to recreate the image I posted. – AK02 Nov 28 '16 at 19:49

Here is what I would do. This may already be what you are doing but to my knowledge there is no quicker way to do this:

1. Draw a line pointing to the right (hold Ctrl).
2. Draw a line pointing upwards (hold Ctrl).
3. Draw a line pointing to the bottom right (or whereever you want).
4. Enable snapping and snap to cusp nodes.
5. Move the lines together until they snap.
6. Select all lines and add arrow heads (in the stroke style dialogue).
7. If desired, group (Ctrl+G) or combine (Ctrl+K).
• Thank you for the answer. I didn't know how to join the three axis (lines) at one point without adding to errors because of manual attempt. Snapping and snap to cusp nodes is what I was missing. – AK02 Nov 28 '16 at 19:49

It's not clear from your question whether you are just trying to recreate the image in your question, draw a 3D grid, or draw something with a 3D grid for reference. Wrzlprmft's answer already covers drawing something like your image, so I'll cover the other two.

# Draw on a 3D grid

Inkscape has a grid that you can used to guide your drawing, such as snapping points to it. To show the grid, on the View menu click Page Grid or press Shift + 3.

The default grid is 2D. To use a 3D grid, do the following.

1. On the File menu, click Document Properties.
2. In the Document Properties on the Grids tab, in the Creation box, select Axonometric grid, and then click New.
If there is an existing grid in the Defined Grids, you may want to deselect Enabled or just remove that grid.
3. If not already visible, on the View menu, click Page Grid.

You can use the snapping tools so that when you draw or move, it'll snap to this grid. If you don't see the snapping tools, on the View menu, hover over Show/Hide and click Snap Controls Bar.

# Draw a 3D grid

If your goal is to draw an object that looks like a 3D grid, use the render isometric grid extension. This is found in Extensions > Render > Grids > Isometric Grid. Experiment with the various options to get the grid you want (or close enough), and then manually edit it by hand if needed. The rendered grid will be a drawn object that you can manipulate and edit.

This would be an alternative to draw something similar to your posted image. Render a grid with a size of 1 in all directions and change subdivisions to 0. Ungroup it and delete paths you don't need, and then make the remaining stuff look however you want.

• Thank you for the answer. It's good to learn these Grid features. – AK02 Nov 28 '16 at 19:50
