v23 v91 1 [[TranslatedPages]] 1 [[TranslatedPages(outdated=Missing description for "Left mouse click will add nodes on overlapping ways")]] 2 [[PageOutline(2-5)]] 3 2 4 = Draw Nodes = 3 5 4 [[Image(source:/trunk/images/mapmode/node/autonode.png)]] ''Keyboard shortcut:'' '''{{{A}}}''' 5 [[TOC(inline)]] 6 [[JOSMImage(mapmode/node/autonode,link=,48,middle,margin-right=20)]] ''Keyboard shortcut:'' **`A`** — is one of the [wikitr:/Help/Menu/Mode#Workingmode working modes] 6 7 7 This tool behaves differently depending on how you use it.8 This mode behaves differently depending on how you use it. 8 9 9 == Standard Mode == 10 == Try it yourself == 11 Open [attachment:josmwiki-actiondraw.osm josmwiki-actiondraw.osm] using menu item [wikitr:/Help/Menu/File "File > Open Location ..."] (`Ctrl+L`). 10 12 11 * If you click on a blank area of the screen you add a new node independent of any existing way.12 13 13 * If you select an end node of a way and then click on a blank area of the screen you add a new node to the end of the existing way. 14 == Standard Mode ==#StandardMode 15 === Create a node === 16 When selection is empty, If you click on a blank area [wikitr:/Help/MapView of the screen] you add a new [[JOSMImage(data/node)]] [wikitr:/Help/Concepts/Object#Nodes node] independent of any existing [[JOSMImage(data/way)]] [wikitr:/Help/Concepts/Object#Ways way]: 14 17 15 * If no node is previously selected and you click between (or very close to) two nodes in an existing way the new node is added on the existing way, between two existing nodes. If two ways cross, and there currently is no node in common at the junction, and you click near the intersection of the two ways, then the node will be inserted into both ways, which will then share a common point. 18 [[Image(ex1-empty-selection-click-on-blank.gif,link=)]] 16 19 17 * If a node is previously selected and you click between two nodes in an existing way the new node is added on the existing way, between two existing nodes, and a way is drawn between the previously selected node and the new node. 20 === Click on node will stop mode === 21 To stop drawing mode, click on selected object (a node) again. This can be done so quickly and some users confuse it with double click. No, you don't need double click: 18 22 19 * If you click near an existing node it draws a "segment" between what was previously selected and the existing node, and this allows you to re-use existing nodes to make a new way / area (so that certain nodes and "segments" can be reused in more than one way/ area). 23 [[Image(ex1-select-deselect-without-double-click.gif,link=)]] 20 24 21 * The drawing stops, if you make a double click when creating the last node or if you click on a node or way segment which is already part of the currently drawn way. 25 === Draw a segment === 26 With empty selection, if you select one node and then click on a blank area of the screen you add a new node and create a new way (with one [wikitr:/Help/Concepts/Object#Segment segment]): 22 27 23 * If you are currently not drawing, then you can select nodes with a double click. If the node is an end node of a line then also the line gets selected. 28 ''Note: click on second node in segment used to stop drawing mode'' 24 29 25 == Alt modifier == 30 [[Image(ex1-selected-node-draw-a-segment.gif,link=)]] 26 31 27 If you hold down the {{{Alt}}} key when using this tool it starts a new way, rather than continuing an existing way. 32 === Click on node will start new segment similar to empty === 33 * If you are currently not drawing, then you can select node with a left mouse click 34 * If the node is an end node of a line then also the line gets selected (leaf node + way in selection); this will be explained in [#Continuousdrawing Continuous drawing (below)] 28 35 29 == Shift modifier == 36 In demo below, left mouse click was used to select first drawing mode, then clicked 6 times at nodes: 30 37 31 If you hold down the {{{Shift}}} key whilst using this tool it disables the "auto-connect" feature. So segments will not be drawn between new nodes. 38 [[Image(ex1-click-to-select-a-node-or-exit-drawing-on-leaf-node.gif,link=)]] 32 39 33 == Ctrl modifier == 40 === Common nodes ===#Commonnodes 41 This is often necessary when you edit highways or streams of the river. 34 42 35 If you hold down the {{{Ctrl}}} key whilst using this tool it disables the snapping to an existing way, allowing you to draw nodes close to, but not part of an existing way. 43 ==== Common nodes with another way ==== #Commonnodeswithanotherway 44 If a node is previously selected and you click between two nodes in an existing way the new node is added on the existing way, between two existing nodes, and a way is drawn between the previously selected node and the ''new node''. 36 45 37 == Note == 46 The ''new node'' will belong to both ways. It's often referred to as "common node". 38 47 39 There is another way to add nodes. 48 Simplest scenario: 40 49 41 When you zoom in to higher resolutions you will note that on a way, between a pair of nodes, there is a {{{+}}} symbol. If you drag this with the mouse it automatically becomes a new node. Using this method it is very easy to modify an existing way. 50 [[Image(ex1-common-nodes-with-another-way.gif,link=)]] 42 51 43 == Angle snapping == 52 ==== Common nodes are bigger ==== 53 It help you distinguish them from other nodes. 44 54 45 You can choose the direction of next segment to make specific angle between segments (0,30,45,90, degrees etc.). 46 To enable this mode press '''{{{A}}}''' again and see helper lines while moving mouse. 47 To fix the direction and move mouse far from snapping line, please hold '''{{{A}}}''' key. 55 First drawn way have a common nodes with old way and second drawn way has no common nodes (details [#Ctrlmodifier how second way was drawn will be explained below]): 48 56 49 Right click on any way segment when snapping allows to use that segment as reference (for example, to draw segment that is parallel, perpendicular or 45 degrees-aligned to the reference segment). Instead of the right click you can also hold {{{Ctrl}}} while moving mouse over desired reference segment. 57 [[Image(ex2-common-nodes-wtih-other-way-and-without-common-nodes.gif,link=)]] 50 58 51 To choose angles, disable showing helper geometry, or disable snapping, use right-click on Angle symbol in statusbar and select corresponding item in popup menu. 59 ==== Left mouse click will add nodes on overlapping ways ==== 60 If two ways overlap, single mouse click will create a common point. 61 62 (stub) 63 64 65 === Double click stops drawing on leaf node === 66 Drawing stops, if you make a double click when creating the last node. This way you don't have to click on last node, but you have to know about this special case: 67 68 [[Image(ex1-double-click.gif,link=)]] 69 70 === Continuous drawing ===#Continuousdrawing 71 Previous way will be continued if both are true: 72 1. nothing was selected OR way in question was selected 73 2. draw mode applied to leaf nodes 74 75 If draw mode applied to non-leaf nodes, it will create a new way instead of continuing old one: 76 77 [[Image(ex1-will-continue-way-on-leaf-nodes-and-wont-at-middle.gif,link=)]] 78 79 ==== Left click on drawn way will stop continuous drawing ==== 80 It doesn't matter if you click on nodes or create a new node in a way: 81 82 [[Image(ex1-click-on-self-when-drawing-will-deselect.gif,link=)]] 83 84 85 === Snaps to existing nodes or ways === 86 Note how nodes and way change color to yellow when hovering over them: 87 88 [[Image(ex1-snapping.gif,link=)]] 89 90 If you click near an **existing node** it draws a "segment" between what was previously selected and the existing node, and this allows you to re-use existing nodes to make a new way / area (so that certain nodes and "segments" can be reused in more than one way / area): 91 92 [[Image(ex2-snapping.gif,link=)]] 93 94 95 == Angle snapping ==#Anglesnapping 96 Often necessary when editing barriers, fences, walls, non-trivial buildings, indoor features and other man-made objects, covered under [wikitr:/Help/Action/Draw/AngleSnap Angle Snapping]. 97 98 99 == Modifiers == 100 === `Alt` modifier ===#Altmodifier 101 [[Image(ex1-alt.gif,link=)]] 102 103 If you hold down the `Alt` key when using this mode it starts a new way, rather than continuing an existing way. 104 105 === `Shift` modifier ===#Shiftmodifier 106 [[Image(ex1-shift.gif,link=)]] 107 108 If you hold down the `Shift` key while using this mode, it disables the "auto-connect" feature. So segments will not be drawn between new nodes. 109 110 === `Ctrl` modifier ===#Ctrlmodifier 111 [[Image(ex1-ctrl.gif,link=)]] 112 113 If you hold down the `Ctrl` key whilst using this mode, it disables the snapping to an existing way, allowing you to draw nodes close to, but not part of an existing way. 114 115 === Combination of modifiers === 116 You may optionally use one or many modifiers at once to get the desired result. 117 118 Here is `Ctrl` modifier used with `Shift` at once: 119 120 [[Image(ex1-ctrl+shift.gif,link=)]] 121 122 == Auto screen center mode ==#ScreenCenterMode 123 Press and release `Ctrl+Shift+F` before drawing to toggle [wikitr:/Help/Action/ViewportFollowing Viewport Following]. If enabled, the screen will automatically center on each newly drawn node. 124 52 125 53 126 == See also == 54 * [[Image(source:/trunk/images/addnode.png)]][wiki:/Help/Action/AddNode Add node ...] 127 * [[JOSMImage(addnode)]] [wikitr:/Help/Action/AddNode Add node…] 128 * [[JOSMImage(mapmode/improvewayaccuracy)]] [wikitr:/Help/Action/ImproveWayAccuracy Improve Way Accuracy mode] (`W`) 55 129 56 130 ---- 57 Back to [wiki :/Help/EditToolbar Edit Toolbar][[BR]]58 Back to [wiki :/Help Main Help]131 Back to [wikitr:/Help/Menu/Mode Mode menu] \\ 132 Back to [wikitr:/Help Main Help]
