This icon is orientated relative to the a section plane b auxiliary inclined plane. Example 3 - the pipe and flange model In this third demonstration of using the setup commands we will create a third angle orthographic layout and add both a sectional view and an auxiliary view to the layout. 1 Open the drawing file MODR2004 FLPIP created in Chapter 33 and a make the MVLAY1 tab active b paper space and erase three viewports leaving the 3D view c make a new current layer VPORTS d load the linetype HIDDEN e model space with UCS BASE and set the LTSCALE variable value to a suitable value f set the following hatch variables HPNAME ANSI32 HPANG 0 HPSCALE 1 g paper space scale the 3D viewport by and move to the top left of the drawing sheet h model space and zoom the model in the 3D viewport to a suitable scale i refer to Fig. for the viewport layouts Figure The Setup View and Drawing Example 3 - the flange pipe model. 306 Modelling with AutoCAD 2004 2 Activate the Setup View command and a UCS option with UCS BASE b view scale c view centre 200 200 d position viewport pick to suit yourself e name MYVIEW1 f options X 3 Repeat the Setup View command prompt Enter an option Ucs Ortho Auxiliary Section enter O R - the ortho option prompt Specify side of viewport to project respond pick lower horizontal line of viewport prompt Specify view centre enter 200 75 R prompt Specify view centre and RETURN prompt Specify corners of viewport respond pick to suit your layout prompt Enter view name enter MYVIEW2 R prompt Enter an option and continue with next part of exercise 4 Setup View command still active with options a select the Ortho option b pick right vertical line of second viewport c view centre
