Update: There is also an addon to draw polar coordinate systems.
Paste the object to the same place ( ctrl+alt+v) and use the tiled clones.Create and place the object which should be cloned.Often the clones will be shifted all over the canvas (probably due to transformation matrices in the xml file). * In Inkscape 0.91 Create Tiled Clones is a bit buggy. Simply combine the unlinked clones ("star" and "bulls eye") and use the result to divide your circle. You can also combine both approaches to create a "radar". In the tab Scale, enter -100/N into the fields Scale X and Scale Y Per row (replace N with the desired number of sectors and yes, Inkscape can calculate 100/N, you don't have to use a calculator).Duplicate the circle ( ctrl+d) and click Edit > Clone > Create Tiled Clones.Divide the circle using the combined object (select both objects, ctrl+/ or Path > Division).Combine the unlinked clones ( ctrl+k or Path > Combine).Select the resulting clones and unlink them ( shift+alt+d or Edit > Clone > Unlink Clone).At the bottom of the dialog, choose Rows, columns and enter N and 1 into the related fields.In the tab Rotation, enter 360/N into the field Angle Per row (replace N with the desired number of sectors and yes, Inkscape can calculate 360/N, you don't have to use a calculator).In the tab Shift, check Exclude tile Per row.In the tab Symmetry, choose » P1: simple translation« and click Reset.Select the line and click Edit > Clone > Create Tiled Clones.
Drag the + to the center 🞱 of the circle. A + should appear in the middle of the line. To do so, click the line twice but do not double click just make a pause between the clicks. Move the rotation center of the line to the center of the circle.Draw a line from the circle's center 🞱 outwards so that the line is longer than the radius of the circle.Divide circles/disks into N pie chart pieces / sectors** This is easy with snapping but nearly impossible freehand. rectangles, ellipses, polygons, arcs, spirals, stars and 3D boxes) and text. This whole approach only works if the lines we are about to generate touch each other at the center. Inkscape can render primitive vector shapes (e.g. For the following steps enable the snapping options » center of bounding boxes«, » cusp nodes«, and » rotation center« as in the following picture. With some effort, you can emulate the linked polar grid tool using Inkscape's tiled clones. The naive method is viable for a few cases (coarse subdivision, angles are multiples of 15°. Press ctrl while drawing the sectors to enable snapping every 15° (snapping angle can be changed in Edit > Preferences > Behaviour > Steps > Rotation snaps every. The naive way is to use the circle tool and its sector (pie chart) mode to draw sectors with the same angle.
