Sheet metal development drawing pdf.
Select flatten from the sheet metal toolbar the sheet metal model flattens out into the surface development used to create it.

A development is a flat representation or pattern that when folded together creates a 3 d object.
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.
As sheet metal features are added to the part it remains at the bottom.
In sheet metal development work some fabrication or repair jobs can be laid out directly on sheet metal.
Parallel line development radial line development triangulation.
1 1 1 scriber lines are drawn on sheet metal with a scribe or scratch awl coupled with a steel scale or a straightedge.
This is due to the fact that drawings manipulated on the sheets by a word processor have been adjusted to conform to space limitations.
Introduction to solidworks sheet metal for technology page 14.
Methods of development of surfaces are.
The drawings on the instruction sheets do not always exactly reflect the specified dimensions however the distances within a drawing are proportional to them.
Layout tools are used for drawing fabrication jobs on metal.
Are manufactured from thin sheet materials.
Sheet metal drawings usually contain views both of the fully formed part and of the flat pattern as in figure sm 4.
Sheet metal construction is the most common application for developments and intersections.
Create a drawing of the sheet metal part.
Called also a pattern the plane may show the true size of each area of the object.
The resulting flat pattern gives the true size of each connected area of the form so that the part or structure can be fabricated.
Many articles such as cans pipes elbows boxes ducting hoppers etc.
When a single part is to be produced in quantity a different development procedure is used.
When the pattern is cut it can be rolled or folded back into the original object.
Construction in full light lines.
A development is the unfold unrolled flat plane figure of a 3 d object.
This development procedure known as scratching is used when the object to be made requires little or no duplication.
