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
