The facade of David Chipperfield's housing in Madrid is made of precast concrete panels with a pinky red pigment. Windows are designed as gaps between panels rather than holes in a wall. We decided to try and describe the materiality of this facade in a digital drawing.
To begin, we took a fairfaced concrete texture (sourced from mayang textures).
The tone of this texture was then manipulated using the hue/saturation tool in photoshop. Found under image > adjustments >hue/saturation.
The pinkish tone is created by ticking the 'colorise' box and then tweaking the hue and saturation sliders until the desired colour is achieved. We then created four tonal variations on the same concrete image by tweaking the lightness slider.
To achieve a glass-like texture for the windows we used a photograph of the Toledo Glass museum by SANAA. This was then desatured and darkened slightly to give the appearance of glass seen from outside a building.
You can then simply import these images into vectorworks - move, rehsape and resize them to create your drawing. (take care with the size of the images - each one should be no more than 1mb)
The method shown above is the easiest and fastest way to may an image based drawing, however if you intend using alot of image based textures in your drawing it can be better to use the 'image hatch tool' rather than than importing images.
To use the image hatch tool, first import the image you want into your drawing using the 'resource browser'.
You can then select a shape and fill it with the image you've imported using the 'attributes palette'.
Then you can edit the size of the image, whether its tiled, constrain its proportions etc by clicking on the little 'pencil and spanners' that appears beside the image in the attributes toolbar.
Say for example you want to create a 3m x 4m wall panel as your base. Start by drawing a large rectangle and filling it with your image hatch. Then follow the instructions below (or simply match the settings in the image below)
- Tick 'Apply to Selection'
- Set the both the X and Y offset to 0
- Untick 'repeat'
- In the 'i length' box type the horizontal dimension you want
- In the 'j length' box type the vertical dimension you want
Once the image is the size you want you can shrink the enclosing rectangle to fit.
(You will need to oversize the image slightly to get a clean fit)
The advantages and disadvantages of imported images vs image hatches are outlined below. You can use the attached sample file to play around with both and see which suits you better.
