How Do You Scale Down A Drawing?

Scaling is a drawing method used to enlarge or reduce a cartoon in size while keeping the proportions of the cartoon the aforementioned. Scales are generally expressed as ratios and the almost common scales used in article of furniture cartoon are 1:1, 1:2, one:5, and 1:10 for reducing and perchance 2:1 for enlarging.

Scaling is used to either:

reduce the drawing in size so that information technology volition fit onto the page, or

enlarge the drawing in size so that all required details are conspicuously visible.

Drawings tin can exist scaled up or down using either a reckoner or a calibration rule.

To scale a drawing using a computer:

split up the measurement by the scale if you want to reduce the drawing in size, or
multiply the measurement past the scale if you lot want to increase it in size.

Example i: Scaling downwardly

A 50mm line is to be fatigued at a scale of 1:5 (ie 5 times less than its original size). The measurement 50mm is divided past 5 to requite 10mm. A 10mm line is drawn.

A 50mm line is to be drawn at a scale of ane:ii. The measurement 50mm is divided past 2 to give 25mm. A 25mm line is drawn.

Example 2: Scaling upward

A 50mm line is to be drawn at a scale of 5:one (ie 5 times more its original size). The measurement 50mm is multiplied by 5 to give 250mm. A 250mm line is drawn.

A 50mm line is to be drawn at a scale of ii:one. The measurement 50mm is multiplied by ii to give 100mm. A 100mm line is fatigued.

To scale a cartoon using a scale rule:

Scale rules allow us to directly set up out measurements onto a drawing without having to convert them to their scaled sizes by using a estimator first.

The whole procedure is made easier because these conversions are already made for us. On a scale rule which has divisions of one:five, each sectionalization represents 5mm and the measurements on the rule indicate this.

Scale rulers.

On a scale rule which has divisions of i:10 each partitioning represents 10mm and the measurements on the dominion betoken this.

Even though the cartoon itself may be reduced in size or drawn at an enlarged size on the page, all dimensioning on the drawing should reflect the correct sizes of the particular being drawn.

This is an example of a scaled drawing. Discover that the height is fatigued at a calibration of 1:10.

Included in the drawing is detail A, and this is drawn additionally at a calibration of 1:i, or total size.
