| − | ==Fine-tuning the graph==
| + | Hello! |
| − | Here is the result of the previous part, with the background disabled.
| |
| − | | |
| − | We need to make the design more symmetrical, for this we will be using the grid.
| |
| − | | |
| − | [[File:Tutorial_picture19.png]]
| |
| − | | |
| − | | |
| − | We start with a 16px square grid and move the center to one of the central nodes.
| |
| − | | |
| − | Click '''Move...''' on the grid dialog and then click on the desired node to move the grid.
| |
| − | | |
| − | No we switch from the '''Edge chain''' tool to the [[Manual/Tools/Edit_Graph|Edit graph]] tool.
| |
| − | | |
| − | The nodes will be snapped to the grid when moved or double-clicked.
| |
| − | [[File:Tutorial_picture20.png]]
| |
| − | | |
| − | After having snapped the four central nodes, we change the grid shape to '''Triangle 1''' to snap the node leading to the top.
| |
| − | [[File:Tutorial_picture21.png]]
| |
| − | | |
| − | We now change to a 12 pixels square grid centered on the tip of the triangle.
| |
| − | [[File:Tutorial_picture22.png]]
| |
| − | | |
| − | We snap the nodes on the top arm of the cross.
| |
| − | [[File:Tutorial_picture23.png]]
| |
| − | | |
| − | Note that the highlighted node does is not making a cusp, the line above is a smooth curve. The underlying image instead has a pointed tip in that location.
| |
| − | [[File:Tutorial_picture24.png]]
| |
| − | | |
| − | With that [[Manual/Editing/Selecting_nodes|node selected]] we change the minimum angle required to trigger a cusp in the selection style dialog. This will affect only the selected node. Since the angle is 180°, something less than that will suffice. A value too low (below 90° in this case) will trigger extra cusps also for the lines leading down.
| |
| − | [[File:Tutorial_picture25.png]]
| |
| − | | |
| − | We now move back down and use a 16 pixels '''Triangle 2''' grid to snap the node leading to the right.
| |
| − | [[File:Tutorial_picture26.png]]
| |
| − | | |
| − | With the same procedure used on the top, we snap the nodes on the right arm of the cross.
| |
| − | The same steps are required for the left arm and the base.
| |
| − | [[File:Tutorial_picture27.png]]
| |
| − | | |
| − | Note that you can snap a bunch of nodes at the same time if they are selected and you use {{app menu|Grid > Snap to grid}}
| |
| − | [[File:Tutorial_picture28.png]]
| |
| − | | |
| − | We snap the other two knots.
| |
| − | [[File:Tutorial_picture29.png]]
| |
| − | [[File:Tutorial_picture30.png]]
| |
| − | | |
| − | Some of the nodes require the same styling as the one on top of the cross.
| |
| − | Make sure that you choose a proper value for the angle.
| |
| − | For the bottom-most knot a value of 100° is too low.
| |
| − | [[File:Tutorial_picture31.png]]
| |
| − | | |
| − | Here is the knot so far.
| |
| − | [[File:Tutorial_picture32.png]]
| |
| − | | |
| − | We can now change the style and display to make it more appealing.
| |
| − | | |
| − | Here is the knot with the same color as the image and a black outline.
| |
| − | [[File:Tutorial_picture33.png]]
| |
| − | | |
| − | Now the knot is complete!
