7.20 First example – isometric drawing – the modelįig. Add lines as in drawing 2 and trim unwanted parts of isocircle.įig. In Isoplane Right construct two isocircles of radii 10 and 20.Ģ. The numbers refer to the items in the list below:ġ. 7.24 shows the stages in its construction. 7.23 is an orthographic projection of the model of which the isometric drawing is to be constructed. Finally using Trim remove unwanted parts of lines and ellipses to produce Fig. Set the isoplane to Isoplane Right and with the Copy tool, copy the top with its ellipse vertically downwards 3 times as shown in Fig. Call Ellipse tool and set to isocircle and add the isocircle of radius 20 centred in its correct position in the outline of the top (Fig. 7.19) working to the dimensions given in Fig. With Line, construct the outline of the top of the model (Fig. Set Snap to Isometric and set the isoplane to Isoplane Top using F5.ģ. Set Snap on (press the F9 function key) and Grid on (F7).Ģ. This example is to construct an isometric drawing to the details given in the orthographic projection (Fig. Examples of isometric drawings First example – isometric drawing (Fig. 7.19 shows these three isoplanes containing isocircles. Its isoplane position is determined by which of the isoplanes is in operation at the time the isocircle was formed. The command line shows:Īnd the isocircle appears. To add an isometric circle to an isometric drawing, call the Ellipse tool. The isometric circleĬircles in an isometric drawing show as ellipses. 7.18 is an isometric view showing the three isometric planes. Repeated pressing of either of these ‘toggles’ between the three settings. These can be set by pressing either the F5 function key or the Ctrl and E keys. There are three isometric angles – Isoplane Top, Isoplane Left and Isoplane Right. 7.17 The AutoCAD grid points set for isometric drawingĢ. Note also the cursor hair lines which are at set in an Isometric Left angle.įig. To set the AutoCAD 2011 window for the construction of isometric drawings:Īnd the grid dots in the window assume an isometric pattern as shown in Fig. Setting the AutoCAD window for isometric drawing Isometric drawing is a 2D method of describing objects in a pictorial form. Isometric drawing must not be confused with solid model drawing, examples of which are given in topics 12-19. 7.16 The result of hatching Isometric drawing Note 7.15 Select Pick Points from the Hatch Creation/Boundaries panelįig. If satisfied the hatching is correct right-click (right-hand drawing of Fig. Pick the points in the front view (left-hand drawing of Fig. In the Hatch Creation/Boundaries panel left-click the Pick Points icon (Fig. 7.14 Setting the Hatch Scale to 2 in the Hatch Creation/Properties panelĤ. 7.13 Selecting ANSI31 pattern from the Hatch Creation/Pattern panelįig. In the Hatch Creation/Properties panel adjust the Hatch Scale to 2 (Fig. In the Hatch Creation/Pattern panel click the bottom arrow on the right of the panel and from the palette which appears pick the ANI31 pattern (Fig. 7.11 The Hatch tool icon and tooltip from the Home/Draw panelįig.
