(Computer Aided
Design)
Have you ever had an
idea but cannot have it manufactured due to lack of drawings?
Do you have a
product but need drawings produced to send for quotations?
Do you have drawings
but just need them printed?
Have you an idea but
don’t know if all the parts will fit together?
Do you need a
computer generated model for presentations or brochures?
What ever your
design or drawing needs let KR Design help you out.
We currently use
professional 3D design software to produce 3 dimensional models of parts that
can then be turned into workshop drawings or exported in various file formats
for use in other applications. Not only can solid models be produced but sheet
metal parts such as enclosures, guards, cowlings etc can be designed, a drawing
produced then converted to a “flat pattern” file that can be used on punching
machines, laser cutters or plotted as a template for manual cutting.
Solid modelling Assemblies sheet metal 2d plotting
Here is an example
of how straight forward solid modelling can be turned into a drawing

This dome
was created as a 3d model, the 3d model was then used to produce the drawing. Due
to the complex nature of the cut outs around the outer surface, the model was
exported as an IGES file that was then used on a 5 axis laser cutting machine
to produce the cut outs on an already spun dome.
Where
more than one part goes together to form an assembly, this assembly can be
constructed on screen to ensure that in theory all the parts mate as desired.
From this “model” both assembly drawings and bills of materials can be
produced.
Example
2:
This
example shows a small hydraulic motor assembly.

The motor
components were all created as individual parts and assembled to ensure they
all went together. The complete model was then “exploded” To produce the
drawing, both the exploded and unexploded views can be shown on the drawing. In
addition to the views a Bill Of Materials is included to assist in part
retrieval.
Sheet
metal is handled in much the same way as its solid counterparts. The design is
first constructed as either a series of sheet metal walls or as a solid model
then converted into a sheet metal shell.
Example
3:

This series of 3
pictures shows how a sheet metal box model can be used to produce firstly a
finished component drawing and secondly the flat pattern. The drawing can also
contain bend lines and a bend table we will be happy to discuss any specific
requirements you have.
sometimes
all that is required is a simple 2d sketch, this maybe just a copy of an existing
drawing because the design has been proved or modifications are very unlikely.
This is a service we can offer using a simple 2d drawing package it is more
economical in the short term because in the case of an assembly all the parts
do not need to be modelled, assembled and made into a drawing. However changes
and modifications can be more difficult to implement on a 2d line drawing
because the rest of the design cannot be checked against it. Our recommendation
is to use this for making copies of an existing design that just needs putting
into electronic format. We also have software now that enables us to scan
pictures; drawings etc and produce DXF files from them. We have found this very
useful when a logo needs to be used within a solid component, for example a
logo on a part that is going to be injection moulded, the logo is scanned in to
the computer then transferred onto the surface of the mould.
KR Design is able to offer a Black and White
plotting service for sizes up to A1.
We can accept your files in a variety of
formats if all you require is just a plotting service.
This could be technical drawings, posters,
line drawings etc
It is also possible to print documents
produced on A4 size paper up A1 size, very useful if you need to do
presentations without OHP or screens
