A development is the unfold unrolled flat plane figure of a 3 d object. Select flatten from the sheet metal toolbar the sheet metal model flattens out into the surface development used to create it. In sheet metal development work some fabrication or repair jobs can be laid out directly on sheet metal. Are manufactured from thin sheet materials.

This is due to the fact that drawings manipulated on the sheets by a word processor have been adjusted to conform to space limitations. Construction in full light lines. The resulting flat pattern gives the true size of each connected area of the form so that the part or structure can be fabricated. 1 1 1 scriber lines are drawn on sheet metal with a scribe or scratch awl coupled with a steel scale or a straightedge.

Some of the more common layout tools are scriber flat steel square combination square protractor prick punch dividers trammel points and circumference ruler. You can place views of the part in both states on the same drawing by creating a multi model drawing. The drawings on the instruction sheets do not always exactly reflect the specified dimensions however the distances within a drawing are proportional to them. Generally a template is produced from an orthographic drawing when small quantities are required larger quantities may justify the use of press tools and the template will include allowances for bending and seams bearing in mind the thickness of material used.

A development is a flat representation or pattern that when folded together creates a 3 d object. Layout tools are used for drawing fabrication jobs on metal. Parallel line development radial line development triangulation. Sheet metal construction is the most common application for developments and intersections.

Many articles such as cans pipes elbows boxes ducting hoppers etc. You will also. This development procedure known as scratching is used when the object to be made requires little or no duplication. When the pattern is cut it can be rolled or folded back into the original object.

Introduction to solidworks sheet metal for technology page 14. Called also a pattern the plane may show the true size of each area of the object. Create a drawing of the sheet metal part. When a single part is to be produced in quantity a different development procedure is used.

Methods of development of surfaces are.
