How to draw geometric cubes and cuboids by hand? When drawing geometric objects by hand, cubes and cuboids are common modeling objects. To master their drawing skills, you need to understand their structural characteristics and perspective relationships. This article will introduce in detail the steps of drawing cubes and cuboids to help you easily master geometric sketching skills.

1. Create a new 800x600, 72 pixel blank document and draw the background.

#2. Select the rectangle tool, draw a rectangle, fill it with a random color (it can be modified later), Ctrl T transform, and draw the top surface of the geometry.

3. Use the same method to draw the other two faces of the geometry, group them and name them large geometry, and rename each layer for later convenience. Revise.

#4. Copy the large geometry, adjust the appropriate size and place it.

5. Next, you need to add a light and dark relationship to the geometry. Select the top shape of the large geometry, change the fill color to white and load the selection. Create a new blank layer and name it 'Top Surface'. Dark part', select the gradient tool, set the gradient from light gray to transparent, add dark parts to the top surface of the large geometry, use the same method to add dark parts to the other two faces of the large geometry to create a light and dark relationship.

#6. Use the same method to add dark parts to small geometric objects.

7. Select the pen tool, select draw shape, set no fill, white stroke 1 point, outline the stroke between the faces of the geometry, rasterize the layer, Execute Filter-Blur-Gaussian Blur, set the radius to 0.5 pixels, change the layer blending mode to Soft Light, and use the same method to outline the edges of the small geometry.

8. Add a shadow to the geometry, load the front and side selection of the large geometry, create a new blank layer under the geometry, fill it with black, execute Filter-Blur-Gaussian Blur, and set the radius to 0.5 Pixel, select the Eraser Tool, erase the excess, leaving only the bottom shadow, and use the same method to create the shadow of the small geometry.

9. Continue to draw the shadow on the side, select the pen tool to outline the shape of the shadow, create a new layer, and add highlights to the shadow. Use the same method to add side shadows to the small geometry.

10. Adjust the details, put all the groups and layers of the geometry into a group, create a new curve layer, Ctrl Alt G to create a layer clipping mask , adjust the curve to make the black darker and the white whiter. At this point, the geometry has been drawn, and you can practice more.

Notes

Using the shape tool to shape is more convenient for later modifications. The light, shade and shadow should be determined according to the light source.
