Scale calculations and dimensioning

 How to calculate the scale when you have the dimensioned drawing.

Remember that the dimensions in the drawing are always real dimensions in mm.

Watch this video that shows an example:

Calculate the real dimensions of an object when you have the drawing and the scale.

Example for reducing scales:

Calculate the real dimensions of a microchip knowing the scale: 20:1 (enlarging scale)

Learn also how to dimension the drawing later

 

Learn now how to dimension a drawing.

Remember that you need to include always the real dimensions in mm.

Remember also that all dimensions that you read on a drawing are real dimensions in mm.

Watch these two videos to understand how to do it:

👉Project Sketchup 04: Draw the scaled and dimensioned views of figures 44 and 45, Include both and their correspondant 3D figure in one single document similar to the ones you did before.

• Draw the views of figure 44 using the scale 1:1.
• Use the 1:10 scale to draw the views of figure 45, 
• Add all dimensions in both 3D and views of figures 44 and 45
• Do not forget the title block where you have to say the scale you are using and the unit in mm

Pictorial Views with sketch up

Activity 003 with sketchup:


Find here the solutions to the exercises 9, 10 and 11 of unit 2


Draw, using sketch up,  four or six of the following figures: (18-4, 18-5, 18-6, 18-7 , 18-8 , 18-9, 18-10 and 18-11)

Export the four figures and paste them to a Word document using Office 365. Remember to include your name and the figure name in each of the four figures. The final result, including the tittle block, should look like this

👉Upload the final pdf  document. If you have time and want to improve your mark you can do the six  figures instead of four.

👉If you did not do correctly the first two activities repeat it and upload it again.👈
