From: David Ramey

There used to be this program called Land CAD that was $30,000 back in the day. It had every plant you could think of and would show you how it would grow in a pot or in the ground.

Never bought it just looked at it a few times. Back then even AutoCAD was wide open. They didn't mind piracy to learn the program but did mind companies doing that although many did.

There is another very useful program that take elevations and determines the run off depending on ground cover but probably a little too much if you are not designing a strip mine or a 4 lane highway. The roads are very similar and some companies do both depending upon where they could make the most money.

I hope this helps but is probably no use whatsoever but it was a little piece of history.

To Boston Area DBUGers,

We have a great program agenda coming up for our next meeting on Nov. 7th at the BSA Building in downtown Boston.

          Case Studies in Using DataCAD

You are invited to join DBUG in our year end meeting that will feature special presentations by DataCAD President & CEO Mark Madura. He will present two case studies for real projects (a new house on a harbor island near Seattle, WA & a house addition in Glastonbury, CT). In the process, he will highlight his own wishlist for new features in DataCAD, some of which will be incorporated into the next release of DataCAD 21. In addition, he will present his amazing detective work in tracking down his spouse's adoptive parents, using both the new DNA tools as well as good old fashioned gumshoe investigation.

Note: It will be in the Pearl Room (across hall from BSA offices on 2nd floor) so they won't kick us out early!

We will issue a formal agenda next week. But let me know if you plan to be there or have any questions.


Evan

Attached (if possible), a pdf which ultimately I'm trying to get to be white on blue like the old blueprints. Anyone have an idea how to convert/ x-ref the linework so it's white on blue? Thanks.

Hi Mal,
 
There's more than one way to go about this, but here's the method I would use.
 
- Start with the original bitmap (convert the PDF if necessary).
- Edit the bitmap in a paint program like Photoshop Elements.
 
Your image is two colors, so that makes it easier.
 
- Replace the line colors with white and the background color with 'blueprint' blue.
- Save the bitmap and insert it into a drawing.
- Use the Enlarge, Enlargement, Calibrate Distance menu and pick two points in the image you know the distance between. DataCAD will calculate the necessary enlargement factor. Right-click twice to get back to the Enlarge menu, then pick the bitmap to resize it.
 
If you need to rotate the image to correct the angle of horizontal and vertical lines, do that in the paint program. Or, you can XREF or Self-XREF the drawing that contains the inserted bitmap, then apply the rotation to the XREF entity.

Try printing with blue lines on white background, saving the PDF file as a png or jpg file and then inverting it using a negative filter in a bitmap editor.

Hi Malcolm,

Is this what you’re looking for? I was curious to see how hard or easy it would be to do. I brought it into Photoshop, selected the blue background (with a very high “tolerance), then “select similar.” Filled the selection with white. Then inverted the selection and filled that with blue.

Best,

David

Just realized you were asking about the “real” style blueprint. How’s this?

Mal,

Is the PDF made from a Datacad drawing, or is it coming from some other source?

Mal,

It looks like X-ref highlighting works only with the basic 256 colors, rather than the full gamut of custom colors. 

To get around this, you can edit color 30 to be the “minus one” and save that palette (using the color palettes/ drawing palettes menu) for use with the “blueprint” file.

I made that color, but I'm having problems getting the xref to be that color. Meanwhile, I selected color29 and that works for the random test lines I drew. Meanwhile, I can make the XREF be color 29 even though I have it set that way in the XR manager. What is the missing step here? I have the color, I just can't get the XR to be it.

Mal,

Color 30 is white - always prints Black. Instead, try this:
Define your own custom color Red = 254, Green = 255, Blue = 255. As close to white as you can get without it actually being true white. 

That will turn your blacks to white and the fuzzy, in-between pixels in the print will be the right shade of blue-white rather than blue-black.

Mark responded and sent me white on blue. Altho he must have re-worked the pdf outside of DCAD, since I did not send a DCAD file.

Thanks for your help. It's a going to be a gift, so there's no project deadline.

Since the background color won't print blue to PDF and I doubt if you want to spend the "ink" to print the background in blue anyway:
Send your pdf to your print service and have them swap the line/geometry color to white and print on blue paper.

Change your DataCAD background to blue.  Change your geometry and text to white.
Take a screenshot.

The way I'd do it:

View the PDF at 200% (for hi-res).

Edit, Snapshot, select the desired chunk. This copies the data in raster form to the Clipboard.

Paste that into your favorite photo editor that will accept pasted input (I use a French freebie called PhotoFiltre, which is super simple, fast & useful.)

Once there:

Go Negative. Now you have white lines on a black background.

Then Replace Color.

But don't replace the black background with "blue." Old blueprints were NOT blue! They were a very dark deep purple! I still have a few around.

See attached, done by the above method. Still not the right color. But you get the idea.

Summary steps:
* Open PDF.
* 200%.
* Edit / Take a Snapshot.
* Select area (Copies to Clipboard).
* Alt-Tab to PhotoFiltre.
* RtClk; "Paste as New Image."
* Adjust / Negative.
* Adjust / Replace Color.
* Choose color.
* Preview / OK.
* SaveAs.

Subject: DBUG› Blueprint. finally
From: Malcolm Blier

Sincerest thanks for all the help. After all the input, I finally went old school, pasted the orig, file linework into a new file and changed the color to color29, which will print close enough to white. The blue is a basic fill.

I printed a piece of it out on my desktop printer. It's not coming out well, but I'll ask my commercial printing co. to verify that it will reproduce as the pdf. shows. If not, back to the drawing board.

Again, as I told Mark Madura, the great thing about this board is no one ever says 'you're on your own, buster...'

Dead thread now but....
 
I would export to sketchup
Choose “blueprint” style under the default styles.
Gives a lovely “aged” look to the drawing.
