![]() Property developer Irvine Sellar, with whom Piano was meeting at the time, said, “He saw the beauty of the river and railways and the way their energy blended and began to sketch in green felt pen what he saw as a giant sail or an iceberg.”įelt pen, graphite and charcoal are the preferred media for concept sketches because they allow for speed and flexibility. One of the most famous concept sketches in architecture is Renzo Piano’s design for the Shard in London, which he drew on the back of a restaurant napkin. Nevertheless, they can also be used to think through layout, site limitations, circulation patterns, solar paths and so on. The sketches are ‘broad sweeps’ that don’t necessarily take into account practical restrictions. Specifically, what is a Architectural Concept Sketch?Īrchitects generally use concept sketches to explore their initial responses to a brief. It is usually a freehand drawing with some basic labels that explain parts, processes and relationships.Ĭoncept sketches are created in the early stages of the design process by architects, engineers, industrial designers, interior designers and others they are not intended to be detailed or even 100% accurate, but to capture the essence of the thing that will ultimately be manufactured. To update the z-value of a graphic the enableZ needs to be true in defaultUpdateOptions and/or in the updateOptions.A concept sketch communicates the most important aspects of a design, whether it’s for a building, a product or something else.To create a graphic with z-value the hasZ needs to be true in defaultCreateOptions and/or in the createOptions.GraphicsLayer needs to be set to absolute-height, relative-to-sceneor relative-to-ground. To be able to manipulate features on the z-axis using the height handle, the following configurations are relevant: Move the selected graphic vertically (on the z axis). The following update operations can be performed on a single graphic with point geometry in a SceneView, if the graphic uses a 3D object symbol layer: Gesture Select multiple vertices and press Backspace or Delete key ![]() The following update operations can be performed on a single polyline or polygon graphic: Gesture Remove the selected graphic(s) from the layer. Scale the selected graphic at the center. Select or deselect multiple graphics to move, rotate or scale. Select a graphic to move, rotate or scale. Once graphics are selected, the following actions can be performed. Use Shift+Left-click to add more graphics to the selection, or remove graphics from the selection, for bulk updating. To begin updating, Left-click on a graphic. The Sketch widget provides users with the ability to move, rotate, scale or reshape graphics during an update operation. Creates a circle graphic with a radius based on the bounding box between the initial click and the cursor location. Creates a circle graphic with radius based on the distance between initial click and cursor location.Ĭhanges the shape from a rectangle to a square or from a circle to an ellipse.Ĭreates a rectangle graphic with a center at initial click, and dimensions based on the distance between the initial click to the cursor location. GestureĬreates a rectangle graphic with dimensions based on the bounding box between initial click and cursor location. The following keyboard shortcuts apply when creating polygon graphics with predefined shapes ( rectangle and circle). Pan the view while creating a polyline or polygon graphic.Ĭreating polygon graphics with predefined shapes ![]() Toggle snapping dependent on the configuration in snappingOptions. The undo/redo stack is for an individual sketch operation, meaning you can redo/undo actions while creating or updating a graphic. Incrementally redo actions recorded in the stack. Incrementally undo actions recorded in the stack. A double-click will complete the graphic at the current mouse cursor's postion. Completes the rectangle or circle polygon graphic in click mode.Ĭompletes the polyline or polygon graphic without the staged vertex. GestureĪdds a vertex for each pointer move in hybrid or freehand mode.Īdds a vertex to the polyline or polygon graphic. The following keyboard shortcuts apply when creating polyline and polygon graphics. Creating point graphics GestureĪdds a point graphic at the pointer location. Pointer and keyboard gestures for creating graphics with different geometries are described in the tables below.
