I am using the latest version of Eaglecad light (6.4.0) and I am
attempting to make a shield for the Olimexino board.

I have taken an existing schematic and PCB layout  of the Olimexino
board in order to get the correct spacing
of the pins that I want this pcb to plug into on the Olimexino PCB.

Wasn't sure how to import the pins for the spacing/locations so I saved
the Olimexino schematioc and board
as a different file name and added my schematic to theOlimexino
schematic.

Then I removed the Olimexino components (except the pins that i want to
use) from the schematic and added my components.

I open the board file and the spacing looks correct for the pins that I
want and then I had to remove all of the components
that I did not want from the original Olimexino board layout.

My ratslist is shown on the board screen but  I would like to change the
dimensions of the PCB in the layout section of Eaglecad
to make more room for my circuits.

I made the board dimensions larger in the Eagle board layout section
manually but then when I try to move a component onto the
newly addded area I get a message that states that the light version of
eagle can't perform the requested action. Some objects extend
outside the allowed board areas.

How can I change the size of this PCB without loosing the
spacing/location of the pins?

Thanks

Hi

Great to see you took time to describe your problem using many words.

Your approach was sound enough but could have been easier.
If you have the board and schematic open at the same time, as you remove the unwanted Olimexino parts from the schematic they are removed from the board at the same time.

Eagle light has a board size restriction of 100mm x 80 mm. If you attempt to place a part origin or part pad outside of that area you get the error you received. You can have other lines outside that area.

Knowing what you wanted to do, I would do the following for that Olimexino board, at the start.
1. Move all of it further into the permitted area
Enter into the command line
Group all;
move (>0 0)(10 10);
2. Manually MOVE that jumper table down below the Y=0 axis with a GROUP then MOVE with CTL key depressed and right mouse.

3. Draw an outline that shows you the 100*80mm restriction.
grid mm;
layer tDoc;
wire (0 0)(100 0)(100 80)(0 80)(0 0);

4. Now you can easily group and move the board to where you want it within the limitations of the light version.

To answer your question another way, you could group singly (See HELP GROUP) each of the pin headers and move them as a group. They will retain their relation ship to each other

Warren-

I had to remove a few things on my PCB layout to fit within the
boundries but the 100 x 80 was more than large enough space.

Thank you very much for your help!

A couple more questions...

1. I noticed that the objects that  iadded do not line up with teh grid.
How do I change the resolution of the grid or snap these items to the
grid in EagleCad light 6.4?

2. I have some grouped items on my borad layout that I would like to
ungroup and delete certain items.
How do I do this in EagleCad light 6.4?

thanks again

Another question...

I am done with my schematics and have run the CAM processor.

Afterwards, I decided to view my gerber files on a viewer before sending
these out to the fab house but
I noticed that there is not board outline in the gerber viewer.

When  I did the wire (0 0)(100 0)(100 80)(0 80)(0 0); to find how much
room that I had,
I then moved this so it was smaller and deleted the board outline that
was smaller.

*Looking at my PCB in Eagle, the brd file looks like this:*
[lh-brd.jpg]

and looking at the gerbers in a viewer, they look like this:

[lh-gerb.jpg]


What am I missing and how do I create a board outline that is set to the
values of the wire that  I created so that I have a board outline on my
PCB?

thanks

*Provide Customers with Professional Lighting Luminaire Design and
Manufacturing Fulfilling the Professional, Functional and Cultural
Requirements*

*Induction lamps have the advantages of high brightness, high lumen
efficiency, low-energy consumption, no flicker and long service life,
possessing outstanding characteristics and excellent luminous effects.
However, only the use of professional lamps can completely reveal the
advantages of induction lamps, and only the use of professional lamps
could be more useful from cultural and functional perspective.*

*The induction lamp-related products available on the market have a
relatively low professional degree, and the phenomenon of putting
different types of matching lamps together can been observed everywhere.
Applications in most cases, where other lighting fixture are far-fetched
for induction lamps, void the advantages and characteristics of
induction lamp, as well as its essential differences from conventional
lighting products. In addition to that, the luminous efficiency is
suppressed, and the differences in heat radiation shall result in
shortening the use- life, lowering the energy-saving efficiency and
seriously impacting the overall quality of products.*

*In terms of functionality, lamps may need to withstand intensive
vibration, air pressure, rain and snow, acid dust erosion, potential
explosions and other events based on different environmental conditions;
From cultural point of view, a lamp is an artistic expression meant to
create the local social environment and pleasant atmosphere, as well as
a best way to engage the innovative experience and customers’ individual
demand. Clients’ individual needs can only be met with professional
design and lean manufacturing, where the professional matching products
of induction lamps (http://www.lvd.cc/inductionlamps.html) could be
provided from the perspective of expertise, functionality and culture.*

*Hongyuan has gathered a lot of experience in the illumination
brightness and distribution curve flux design, overall lighting planning
and other lamp designs, with profound technical strength. The company
has developed and produced various professional products of induction
lamps, including street lamps, tunnel lights, high bays, explosion-proof
lamps, flood lights, underground lamps, down-lights, yard lamps, ceiling
lamps and so on. The company makes its technology and services move
forward to stand in the forefront of the market to listen to the actual
demands of customers directly, then designs and makes customized
products especially for them. If it reaches a certain production volume,
the company can provide free designs for customers, as well as to meet
the focal needs of high level and high standard from customers in the
one-stop services provided by Hongyuan.*

*The LVD manufacturing base covers an area of nearly 200mu (about 13.34
acres), with the complete manufacturing cycle of research and
development, and production of ballasts, PCB, glass bulbs and tubes,
lamps, fixtures and packages, and it always controls all aspects and
phases of production on its own, which closely reflects the strict
requirements of Hongyuan for product quality and their stringent
attitude for being highly responsible for customers.*

*LVD Mold Workshops have a complete set of mold equipments with high
standard and high level, creating various lamp molds completely adherent
the design of lamps, and then use a whole set of production proceedings
to test the mold process and mass-production, to ensure the product
quality of manufacturing in enormous quantities. In fabrication, the
lean production makes the product quality penetrate into every detail,
to show the excellent quality of Hongyuan’s induction lamps, hoping
customers to be satisfied because the product quality meeting or

Thanks Warren-

I just recently returned to this schematic and openned both the
schematic and the layout and added a few components but
the layout did not pick up the parts that I added to the schematic. Is
there a way to get these added to the layout as well?

Please advise

thank you

Hi Edgar,

That's correct, EAGLE defines the work area using a rectangle whose
bottom left corner is at 0,0 and top right corner is at 100mm, 80mm.
