Here is the object in 3D along with its 2D drawing which we will learn to model in this post. I recommend you to switch to drafting and annotation workspace for this drawing, you can also download CAD files for this.Related:Step 1Create the following circles using CIRCLE command from draw panel of home tab, make sure circle with radius 2.5 units has its center on the circumference of the circle with radius 26 units.Step 2Select Polar Array from the Modify panel of Home tab and select two small circles on the top of geometry. Now specify the center of the largest circle as the center of the array and enter 4 in the Number of Items field. You will get an array like the one shown in the image below.Step 3Delete the biggest circle and select FILLET command now enter R on the command line and type 7 as the fillet radius. Now apply this fillet at the intersections of the circle with R2.5 and R22.5 as shown in the image below.Step 4Trim all the geometries to make it look like the image below.Step 5Type J on the command line and press enter then select complete geometry and press enter again.

This will join all external 2D segments into a single unit. You may need to repeat the JOIN command couple of times to join the geometry completely. Step 6Change view to southwest isometric and visual style to Shaded from Views and Visual styles panel of Visualize tab.

Step 7Type PRESSPULL on the command line and click at a location inside the geometry, make sure you are clicking inside the geometry and not on the geometry. Enter the height of 3 units on the command line and press Enter again.This command will add the thickness of 3 units to the 2D geometry which we have made so far and your drawing will look like the image shown above. Step 8Create a circle of R17 on the top of the object made in previous step, but for making a circle on top plane you need to make sure that dynamic UCS is turned on. Press F6 to turn on dynamic UCS then select circle command and move your cursor to the top plane and click at the center of geometry for circle’s center and enter a radius of 17 units and press Enter again.Step 9Type EXT on the command line and press enter then select the circle we have drawn in previous step and press enter again. Enter a height of 5.5 units and press enter again to exit the extrude command.Step 10Now create another circle of radius 14 units with the same center on top of geometry which we have drawn in the previous step and extrude it by 3.5 units the same way we did previously.Step 11Now type UNION and Press ENTER then select complete geometry and press enter again, this will ensure that all geometries get combined as a single unit. Step 12Create a circle of R11 on the top most surface of the geometry.

Now type PRESSPULL on the command line and press Enter then click inside the circle of radius 11 units and enter -12 as depth of geometry, this will make a hole in existing geometry.Step 13Type F on the command line and press enter to start fillet command, type R on the command line and enter a radius of 1.5 units for the fillet. Now select the edge between the flat piece and the biggest cylinder as shown in the image below and press enter twice to exit the command.The final geometry will look like the image shown above.

Positivism -v- Interpretivism. What is Positivism and Interpretivism? The view that. So what is the difference between theory and method? Interpretivism theory in education. And actions that are not easily made numeric. Positivist work, however, seeks to identify those details with propositions that then can be tested or identified in other cases, while interpretive work seeks to combine those details into systems of belief whose manifestations are specific to a case. Among them positivism and the interpretivism are two different major paradigms. Starting with interpretivism that is the most realistic in HRM and then combining. Positivists emphasize that the relationship knower to the.

Considerations for TrueType FontsIf a PDF viewer does not have access to a font that you used in a drawing, it displays the affected text using a substitute font. Often, the substitute font doesn't match up to the original font. Consequently, the text in the drawing can appear different than the text in the PDF file.You can prevent font substitution by capturing the font in the drawing and embedding it in the PDF file. Alternatively, you can convert all text to geometry. Converting text to geometry ensures that the text in the PDF file is identical to that of the drawing. However, the PDF file size increases and text pixelation can occur when you view the PDF file at a high magnification.

You can reduce pixelation by increasing raster image quality. Limitations. Resolution - The highest possible resolution of PDF data is 4800 dpi. 3D Visual Styles - All viewports, model space or layout that have a 3D Visual style applied to them are converted to raster images when plotted to PDF. As a result, drawing information such as the layers within the viewport is lost.

Furthermore, text within the viewport is not searchable, and hyperlinks are removed. Printing PDF files - If you use the Adobe Acrobat Reader default printer settings to print a PDF drawing, transparent objects and wipeouts might not print correctly. If the PDF file contains transparent objects, you may need to adjust some settings in Adobe Acrobat. Set Transparency Flattening to 'Print as Image' or reduce the Raster/Vector Balance in Adobe Acrobat. Refer to the Adobe documentation for more information. Loss of precision - PDF stores data in single precision numbers, while DWG stores data as double-precision numbers.

This loss of precision can become apparent as:. Round-off errors on computed locations of objects, such as the locations of tangent points, and arc radiuses and their endpoints. Round-off errors on large coordinates such as those found in geolocated drawings. Deformities and round-off errors in tiny objects when a drawing contains very large objects as well as tiny objects.
