What does hatching mean architecture?
Hatches are 2D patterns in architectural drawings such as plans and sections that represent the type of materials for any surface (wall, floor, roof etc). These are important for effective communication of the correct building materials.
What is hatching in design?
Hatching (French: hachure) is an artistic technique used to create tonal or shading effects by drawing (or painting or scribing) closely spaced parallel lines. (It is also used in monochromatic representations of heraldry to indicate what the tincture of a "full-colour" emblazon would be.)
What does hatching mean in CAD?
Simply put, “Hatch” is a command in AutoCAD that lets you fill in an area with a pattern. There are three standard hatch types to chose from: pattern, solid, and gradient.
What are the types of hatching?
Let's take a look at six basic forms of hatching and crosshatching.Parallel hatching. ... Contour hatching. ... Crosshatching. ... Fine crosshatching. ... “Basket” or “woven” hatching. ... “Tick” hatching.
What is hatching of wall?
Hatching styles are patterns used on drawings for the easy identification and location of different types of commonly-used materials, objects and spaces.
What are the principles of hatching?
Hatching is created when non-crossing lines are used to indicate the value on or around an object. The value added to the object is dependent on the location of a light source. More marks are added in the areas of core shadow and cast shadow, while less marks should exist in lighter areas.
How is hatching used in CAD drawings?
The hatch command in AutoCAD is used to fill an area or selected objects with a hatch pattern or a fill.
How do you hatch in CAD?
Hatch or Fill an Object or an Area On the Hatch Creation tab > Properties panel > Hatch Type list, select the type of hatch that you want to use. On the Pattern panel, click a hatch pattern or fill. On the Boundaries panel, specify the how the pattern boundary is selected: Pick Points.
What is a hatch pattern?
A hatch pattern is consists of different combinations of horizontal, vertical or diagonal lines and are considered vector patterns.
What's an example of hatching?
0:498:35In some ways the simplest type of hatching is single parallel hatching it's one I really likeMoreIn some ways the simplest type of hatching is single parallel hatching it's one I really like because it's very clean and tidy tone is created with uniform parallel lines.
What is the difference between hatching and hatching?
A hatchling is a bird or reptile that has just recently emerged from an egg. "The yellow hatchlings looked around the nest in amazement." Hatching is the verb describing the process of breaking out of the shell. "The eggs are not hatching yet, but they will very soon."
What is the hatching period?
Incubating chicken eggs is a 21-day process and requires an egg incubator to help control temperature, humidity and egg turning.
How is hatching used in CAD drawings?
The hatch command in AutoCAD is used to fill an area or selected objects with a hatch pattern or a fill.
What is hatching in weaving?
Hachures is a weaving technique used to let two colours run into each other. It is often used with a lighter and darker tone of the same colour to create shading. Hatching is a technique used more often today to create a shift in colour.
How to learn hatching?
The best way to learn is to practice and experiment as often as you can . One fun activity is to make a contour line drawing of something and photocopy it several times over, then practice different styles of hatching on each one.
What happens when you increase the density of a collection of hatch marks?
When you increase the density of a collection of hatch marks, the area will appear darker, which can be useful for creating value variations as we’ll see. 2. Contour hatching.
What is hatching in drawing?
Anywhere you put hatching in a drawing, that area will appear darker or in shadow, and anywhere you don’t will appear as a highlight. All of the hatching is vertical in the example below, but it can be at any angle.
What are the different forms of hatching?
Let’s take a look at six basic forms of hatching and crosshatching. 1. Parallel hatching. Parallel hatching is one of the most basic forms of hatching, and it’s still a very effective way of demonstrating value (light and dark) in a drawing. It consists of rows of parallel lines placed closely together.
What is cross hatching?
Crosshatching. This is such a well-known method that nearly every artist has encountered it, and it’s exactly what it sounds like. After laying down one pass of hatch marks, another set of hatch marks are drawn on top, usually in a perpendicular or near-perpendicular direction to the first set.
What is the best tool for crosshatching?
The method is the same as above, with several layers of cross hatch marks rather than just two, to create even more nuanced differences in tone and value. A fine-line pen is the best tool for fine crosshatching, as the close marks will appear to blend together from a distance.
What is the graphic style of hatching?
6. “Tick” hatching. This is another very graphic style of hatching, consisting of very short parallel strokes or “ticks.”. Because the marks are so small and short, you can almost pile them on top of one another to create density, without worrying about crosshatching.
What Is Hatching And Why Use Hatching In The First Place?
Hatching is the uniform texture you get from using a pencil, crayon or pen to fill in large areas with shades of color.
What does smudged hatching mean?
Smudged Hatching =smudging the color on your sheet of paper with no concern to texture whatsoever.
How much of your work is line drawing?
Your line drawing counts for 80% of your whole work. Use hatching to make that line drawing look it’s best, not to try to cover up mistakes.
What does it mean when you make the same mistake?
This is a very common issue with beginner or intermediate students. If you are making the same mistake, then it’s just a sign you don’t have the basics handled… so don’t worry too much about it.
Can you mix two types of hatching?
There’s really no efficient hatching that could do both of these! So WHY NOT MIX TWO TYPES OF HATCHING.

Hatch Patterns
Material hatches were traditionally drawn by hand so it was important that each drafter was consistent in how they drew the hatch symbols. However, as we have transitioned to computer design software like AutoCAD and Revit, designers can simply select the hatch from a library and make modifications to the scale, angle, or fill region.

How to darken squiggles?
To darken, and more squiggles over the squiggles. Blur your eyes to find areas of uneven value and fill these with additional marks. Start with a series of loose scribbles. To deepen the value, add more squiggles on the squiggles.
How to avoid hatching lines?
Avoid hatching lines that are at an angle that is close to that of the first set. This creates odd patterns of dark and light.
What is hatching in pencils?
Hatching is a great way to create value with both pen and unblended pencil. Here are a few variations of fast and effective hatching technique.
How to make a longer line?
If it will take multiple strokes to make a longer line, try leaving little irregular spaced gaps between one line and the next instead of overlapping the strokes. Overlap strokes often make irregular blotches while irregular spaced gaps add a little sparkle to your technique.
What is cross hatching?
Cross Hatching. Cross hatching is a fundamental technique to deepen values. There are a few subtleties with this technique that are often overlooked. The most important is to watch the angles of the cross lines, avoiding right, and sharply acute angles. Start with a set of parallel lines.
Can contour lines wrap around rounded shapes?
Fan contour lines from a narrow pinched shapes into open shapes, Contour lines can wrap around rounded forms. Add a second set of smaller lines from the larger edge toward the smaller. Cross hatching lines can also wrap around the contours. You can also add additional levels of hatching to farther deepen values.
Why do lines show through in drawing?
If your lines show through in your final drawing, their direction can help to show changes in the planes of the object you are drawing. See Showing Planes with Line Angle. Alternatively, you can keep the line direction consistent across planes, reducing detail in the shaded area and allowing it to recede into the background.
What is the difference between pointillism and stippling?
The main difference between stippling and pointillism is that pointillism relies on the use of color theory and optical mixing to create a picture, while stippling uses multiple dots of monochrome or tones of black and white to create an image. Stipple sketches are done with varying nib sizes, which allows a wide range of dot sizes, densities and values.
What is pointillism in art?
On the other hand, stippling is a technique that was invented by Giulio Campagnola, an Italian engraver who translated Venetian oil paintings of Giorgione into the medium of engraving. Simply speaking, stippling creates light and shade with the use of dots, a kind of black-and-white pointillism.
Why is sketching important?
From diagrammatic sketches to more analytic and life drawings, sketching is a way to build understanding and to interpret both ideas and what we see. Analytic sketches allow us to record our observations and filter them through an individual perspective, whereas diagrammatic sketches are more often used to depict adjacencies and relationships between ideas that can be abstract. The following list compiles five distinct types of sketching, each lending themselves to different ways of sharing information and illustrating design concepts.
What is sketching in art?
At its most basic form, sketching is usually done as a line drawing. Defined as drawings done using only lines that vary in width and density, these sketches produce a range of depth. While lines do form the basis of all drawing styles, this specific type of sketching includes straight or curved lines placed against a (usually plain) background. Emphasizing form, they can be everything from continuous line drawings where the pen or pencil never leaves the paper, to caricatures and realism. However, they often don’t depict shading or light.
How do line sketches create images?
Line sketches create images by indicating the edge of a two-dimensional (flat) shape or a three-dimensional form with contours. They also include doodles — an informal types of line drawing that is done in a more subconscious and less attentive way. Drawn quickly and with simple, clear lines, doodles can be inspiring illustrations of our ideas and our impressions of the world. It’s good to begin here, as line drawings encompass one of the seven elements of art: line, color, shape, form, texture, value, and space. There are also implied lines, which aren’t physically present, but generated by our minds as we sketch and produce relationships between different subjects. It’s key to remember that by varying your line weight, you can capture movement and suggest when one object is in front of the other.
What is a thumbnail sketch?
Thumbnail sketches are quick drawings used for brainstorming and investigating the appearance and visual impact of ideas. These can span aspects of geometric proportion, configuration, scale and layout. You can try out several ideas and zero-in on the most likely layouts before beginning a project. You can use any medium, and these sketches are usually very small. They can also be used as a memory aid to help you remember important features of a subject, or plan out a more detailed drawing or storyboard. You can quickly experiment with format and composition, from horizon and perspective.
What is the difference between drawing and sketching?
Drawing is at the heart of architecture. As the foundation of practice, it centers on ideation, technical detailing and self expression. Sketching is a type of drawing that allows designers and artists to explore concepts in multiple styles. Usually done for preliminary studies or quick idea generation rather than conveying a finished product, sketching is often less detailed. It’s tied to time, movement, and process as a way to capture a mood or the key features of a subject.
What Are Line Types and Line Weights
One of the biggest challenges architecture students have is using the correct line weights and line types in their drawings. Incorrect drawing conventions can cause problems because people cannot read drawings properly when you present drawings with inaccurate line weights and line types.
Architectural Line Types
Every line in your drawing is going to be a particular type. We start with some simple line types:
How To Use Architectural Line Types
To determine which line type to use, look at your drawing as a representation of the final built form and ask yourself:
Other Line Types
As an architect, mastering these three different line types will take you a long way in your drawings.
Architectural Line Weights
Architectural line weights refer to the thickness of lines in a drawing. Any scale drawing representation will use lines of different thicknesses. Thicknesses within an individual drawing and across a drawing suite help communicate information about drawn elements and how different elements relate to one another.
How To Use Architectural Line Weights
We use architectural line weights slightly differently in each drawing. But let’s start with plan, section and elevation and refer to line weights as thickest to thinnest.
What Next?
As you start to research and find different drawings that communicate well, save them. Start to create a library of examples and drawing styles that you like. Over time, you will see different adjustments to the actual line weights. Still, the philosophies of thickest to thinnest very much stay the same.
