Suppose I want to draw a Heat Exchanger.The following are the steps and the methods I employ in Excel. Make sure that the Excel Drawing Toolbar is inserted into your worksheet. You do this by clicking on View - Toolbars and checking the box next to "Drawing". Select the rectangle object in the Drawing toolbar and draw: Next, select the oval object and draw: Select both objects and make the Line Style thicker (2-1/4 points): Draw two more rectangles (& make them thicker): Join the two small rectangles, select the arrowhead pointer and draw an imaginary rectangle around the two; then click "Draw" & "Group". The two rectangles are now one. Select the grouped rectangles and make a copy, placing them at the big rectangles ends: Now, copy the oval (ellipsoid) and place the resulting two objects on each end of the large rectangle: Select each ellipsoid and then "Draw" - "Order" - "Send to Back"; move the objects so they align with the "shell" of the heat exchanger. Note: to facilitate this close work, you can amplify the view by making the spreadsheet either 200% or 400% bigger. Now draw a rectangle and make a copy of it also; zoom up to 200%; Move the rectangles over the vertical seam on the two elliptical heads and position them so that they cover each vertical seam. Size them so that they fit just over the seam. Now with each rectangle selected, click on Format Autoshape - colors and lines - no line. This will make the rectangles invisible if they are ordered to the front of the object - which is normal. Now you can make the nozzles and baffles to finish the object by drawing rectangle: Form the nozzle with flange and hide the bottom line; place the baffle rectangle and select the dash style line. Make copies of the flanged nozzle and place them where needed; you can rotate or orient the nozzles. You should "Group" your finished object so that you can move or copy it when needed. Another neat thing that can be done in Excel Engineering sketches is that a liquid content can be easily depicted. For example, draw a storage tank: 2 Draw an isosceles triangle 1 Draw a rectangle 3 Join them together 4 Draw another rectangle (or copy the one above) and make it a lighter line; insert it at the bottom of the larger rectangle. You can use the "nudge" feature on the Draw menu to precisely position the piece where you want it. You can also use the "Zoom" feature to see the line detail better. 5 Now use the object "Fill" feature (after selecting the small object) It's when you don't press any key and draw the line that you "freeform". With enough practice. Also.large rectangle 1. You have to have practice. You also have to know that there is no way you can control your pulse to draw a perfectly curved line.small rectangles with "no lines" and put "forward" Now. This allows you to "cheat" by pinching in the points given on the objects periphery and adjusting them so that they fit the curved portion that you want to outline. Don't forget to use the "Zoom" feature and do your point pinching with the object amplified so that you can clearly see what you are doing. select the freeform line from Autoshapes . You can also fill in curved or odd-shaped objects by creating a closed object with the "freeform" line feature: Draw the vessel object as you want 1.Lines and draw the contents of the bottom of the tank in the form of an object: Don't fret if you don't get the hang of it at the first attempt. you draw a perfectly straight line. No one does. know that when you hold the shift key and click while drawing the freeform line.like the following: .5 and select a color to fill in the object. you can do this pretty decently. Another good technique that you can use to make things easier is to make your objects "oversized" and then simply reduce them by "squeezing-in" the outer boundaries of the objects after you select them .ellipsoid sent to the back 2 . Excel knows this and gives you the "edit points" feature which you bring up by right-clicking on the object and selecting the "edit points" feature. Don't worry. . Toolbars Now copy the previously constructed nozzles: .Let's draw a distillation tower: View . eadsheet either Locate the nozzles on the vessel as needed. Now any seams or other lines that are not needed can be "hidden" by overlaying a rectangle that has no li to it. The "Order" of the objects is the trick to hiding lines or parts of objects you don't need. Simple Valve symbols are made by selecting Autoshapes and Basic Shapes such as the equilateral triangle: This is copied and re-aligned to form: Gate Valve To this you can add other objects and lines to produce: . . . in the form of an object: . . . g a rectangle that has no lines u don't need. quilateral triangle: . . 2 psia 3 ft Gasoline @ 100 oF 3 ft .
