Tipps zur Bemaßung

Summary

In this instructional video, the presenter demonstrates how to accurately draw measurement and auxiliary lines in technical drawings. The video emphasizes the importance of selecting two reference edges, one for height and one for width, to ensure consistent and precise measurements. It also covers the concepts of basic, location, and form dimensions, highlighting how to check for missing or duplicate measurements. By providing practical tips and examples, the video guides viewers on ensuring their measurements are correctly applied and verified, preventing common errors in technical drawing.

Takeaways

• 😀 Choose two reference edges (height and width) as your 'maßbezugskanten' for accurate dimensioning.
• 😀 Start all measurements from your reference edges to maintain consistency and avoid confusion.
• 😀 Extend the reference edges to the first relevant line when measuring for width and height.
• 😀 For height, measure from the lower reference edge and extend the line to the first crucial dimensioning line.
• 😀 Always add dimension arrows and numbers after drawing the measurement lines to complete your drawing.
• 😀 Double-check that all necessary measurements are included to prevent missing or double dimensions.
• 😀 The 'Grundmaß' refers to the basic dimensions, like the overall size of the object (depth, height, width).
• 😀 The 'Lagemaß' defines the position of a feature (e.g., cutouts) in relation to the object's edges.
• 😀 The 'Formmaß' determines the size of a change or modification, such as the dimensions of a cutout.
• 😀 Use subtraction to calculate 'Formmaß', like subtracting the position measurement from the overall dimension.
• 😀 Checking for completeness of measurements is essential, especially when there are changes or features like cutouts.

Q & A

What is the main focus of the video?

The main focus of the video is to explain how to correctly mark dimension lines and reference lines on technical drawings, ensuring accurate measurements without errors.

What are the two reference edges mentioned in the video?

The two reference edges mentioned are the height edge (Höhenkante) and the width edge (Breitenkante), which are used as the basis for all measurements on the drawing.

What is the purpose of using the height and width reference edges?

The height and width reference edges (Maßbezugskanten) help ensure that all measurements are consistent and accurate by providing clear starting points for marking dimensions.

What does the term 'Maßbezugskante' mean?

'Maßbezugskante' translates to 'reference edge,' which refers to the specific edges from which all measurements on a technical drawing are derived.

What should be done when measuring the width on the drawing?

When measuring the width, you extend the width reference line (Breitenkante) and mark the first significant line that needs to be dimensioned. Then, continue to the next line, and so on.

How do you measure the height in the drawing?

To measure the height, extend the height reference line (Höhenkante) and mark the first significant line that needs to be dimensioned, following the same process as with the width measurement.

What is a common error that people should watch out for when dimensioning?

A common error is double dimensioning or missing a measurement altogether, which can cause confusion and inaccuracies in the drawing.

What are the three key measurements to verify when checking a drawing?

The three key measurements to verify are the Grundmaß (base dimensions like depth, height, and width of the body), Lagemaß (distances of cut-outs from the edges), and Formmaß (size of the modification or cut-out).

What is a 'Lagemaß' and why is it important?

A 'Lagemaß' refers to the location of cut-outs or modifications in relation to the edges of the body. It is important for determining how far these changes are from the reference edges.

How is the 'Formmaß' determined?

The 'Formmaß' is determined by calculating the size of a modification or cut-out, often based on the Lagemaß. For example, the hole's size can be calculated by subtracting the distance between the edges from the total dimension.
