ULP to change class of a net?

jpadie — Tue, 27 Jan 2026 17:17:38 GMT

I've tried things like

if (classNum > 0 && sClass != classNum) {

exit(S.class.number = classNum);

}

and

if (classNum > 0 && sClass != classNum) {

S.class.number = classNum;

}

etc

but nothing seems to be working. What I am trying to do is to reassign a known list of nets to a specific class.

any help gratefully received

looking for someone to help capture screenshots of old EAGLE font

darthisurus — Thu, 17 Jul 2025 01:26:01 GMT

I'm looking to recreate the old angular font featured in EAGLE/CADsoft. I downloaded a trial of EAGLE FUSION 360 and it didn't have it (or I somehow couldn't access it).

I'd like to create what was in EAGLE as actual usable TTF or opentype font. Want to use it in some design/art projects.

Manual trace bottom track across bottom polygon: how to?

earckens — Sat, 01 Mar 2025 11:40:15 GMT

I need to get a bottom trace between two via's that currently are connected with an airwire.

However, when doing the trace at the bottom, the polygon does not cede to make way for that trace.

bom3_csv_v2.ulp adds many commas

H_Lenk — Tue, 12 Mar 2024 10:48:50 GMT

At my office desktop computer (windows 10, only) I encounter since last year a funny problem when using the ULP: bom3_csv_v2.ulp and also load my parts-parameter file.

When I generate Parts and Values as EXCEL files, the rows of the CSV files start with the parts-parameters and then are filled up with commas until column #470.

It is not nice to work at those files with EXCEL!

This problem does not happen with my home desktop PC.

Because I am not smart enough to understand and change the bom3_csv_v2.ulp program, I wrote a tiny Pythion program to get rid of those surplus commas.

#!/usr/bin/env python

# -*- coding: utf-8 -*-

# BOM_Comma.py

# Copyleft 5.3.2024, lenkh <lenkh@Uni-Mainz.de>

# Program to remove trailing commas in files generated with the

# EAGLE ULP program: bom3_csv_v2.ulp at my Uni-desk PC

import sys

import glob

print()

print(glob.glob("*.csv")) # show local files with csv extension

print()

s = input("Enter EAGLE-BOM file name with many trailing commas => ")

in_file_name = s + ".csv" # input file

out_file_name = s + "_new.csv" # output file

with(

open(in_file_name, "r") as file_1,

open(out_file_name,"w") as file_2

for s in file_1: # read the input file

print(s) # original string

# find first occurrece of the many ,,,,,,,,,,,

print()

i = len(s) - 2 # point to right most character

comma = s[i]

while s[i] == comma: # scan string from right to left

i -= 1 # decrement pointer

# copy the string without trailing commas

out_s = ""

j = 0

print(i,j)

for j in range(i+1):

out_s = out_s + s[j]

print(out_s) # show output string

file_2.writelines(str(out_s) + "\r") # write to output file

file_1.close()

file_2.close()

Is there any way to get the license file again?

Air Wires are not showing

Collins — Wed, 04 Jan 2023 16:58:28 GMT

I have taken an existing Eagle design and added some components and signals to the schematic. When I go to the PCB file, which is always opened with the schematic for back annotation, the parts have been placed but there are no air wires shown from those parts. How can I fix this?

Simple design Arduino UNO shield

dottest37 — Thu, 15 Sep 2022 21:58:22 GMT

I have a special need and nobody makes my specific shield, so I figure out I would try to make my own, and probably have it manufactured by pcbway or the likes.

I have access to Fusion 360, and I have some experience with it for 3D modeling, but none with electronics design.

Does anyone has some recommendations in terms of where to start? I downloaded a template for arduino uno, but I cannot figure out how to use it as overlay for my board and match the pins, etc.

Also, I dont know exactly how one pick the components in a way that pcbway or other manufacturer can source them for you and install them (same size, specs, etc).

Again, im new to this process so Im looking for some guidance.

Thanks !!

Autorun script/upl on project load

fa1212 — Thu, 05 May 2022 14:57:30 GMT

Hello, I'm quite new to EAGLE and a noob regarding ULP scripting as I've just recently moved to this software.

Is there any way on which I can "embed" a script.scr or a upl to one of my project (or EPF file) and have it automatically executed on project load/open?
It will be usper usefull to have as I'll be able to share projects with colleagues and the scripts will auto-setup the environment and settings on their machine.

Revit failed to Load ImagePath

Xamaa — Fri, 29 Apr 2022 20:36:36 GMT

I try to place a Temporary In-Canvas Graphic in Revit like this:

Renderforest mod apk free download

var activeUiDoc = document.Application.ActiveUIDocument;
var activeDbDoc = activeUiDoc.Document;

using (var graphicsManager = TemporaryGraphicsManager.GetTemporaryGraphicsManager(activeDbDoc))
{

try
{
var insertionPoint = activeUiDoc.Selection.PickPoint("Select insertion Point");
var logoData = new InCanvasControlData(@"C:\Program Files\Autodesk\Revit 2023\uniE1D2.bmp", XYZ.Zero);

var index = graphicsManager.AddControl(logoData, ElementId.InvalidElementId);
} catch(Exception ex)
{
return;
}
}

But I get "Failed to load the image from specified path." Error message. I have tried various different paths, the Error stays.

Is there an Issue with the Revit 2023 Api? What can i try to get my image displayed?

Thanks for the help.

Eagle V7: library variant issues

Oppie51 — Thu, 24 Feb 2022 16:36:47 GMT

Eagle ULP change text

msr.andi — Mon, 07 Feb 2022 21:22:51 GMT

I'm not sure if this is the right place for Autodesk-Eagle ULP but....

I want to change the text of a TEXT field in BOARD.

But I'm sorry, I do not find how to do that.
I have to build a cmd string,which will be executed at exit(cmd) ???
How do I determine which text field should be changed with this cmd ( or on commandline in BOARD)?

I can loop through all text field - no problem. I can read the values - no problem.

but how to change a specific text field?

Can anybody help me please?

New to EAGLE. Cannot delete text in schematic.

JayeKaye — Sun, 19 Dec 2021 17:49:52 GMT

Can't edit it, move it, nothing. This cannot possibly be such a hassle. What am I missing? I have no tOrigins or bOrigins, so that one reply to the other guys question from 6 years ago doesn't work. Using the free download, FWIW.

HELP, Pads are suddenly showing on all parts in schematic

cfields58 — Thu, 07 Oct 2021 17:32:15 GMT

I am using Eagle 7.7.0 Ultimate. I was trying to import a bitmap with an existing user script and may have hit another script.. before this happened. Then I went to print it to see if it worked and the pads started showing in green in the schematic.

I do not see a way to turn this off.

prevent pads holes being filled

will.mendil — Sat, 29 May 2021 08:46:59 GMT

In Eagle (v9.6.2), the routes fill the holes of my pads. hence when I want to print it, the pads are all black, no drill holes. What am I missing?

"Save selection as design block broken"

smashcat — Mon, 24 May 2021 00:42:01 GMT

Has this option ever worked? I've become used to just creating a copy of the whole design, then removing parts I don't need, then saving the rest as the design block. The "Save selection..." option for design blocks does absolutely nothing. No status text, no popups, just nothing happens, or it locks up something in Eagle, so the selections are then broken for everything until I restart Eagle (i.e. the select tool no longer works at all ).

It would be a nice feature to have for sure.

Import pre-made .brd

subhumanaudio — Sun, 28 Mar 2021 00:58:46 GMT

Greetings, just learning Eagle and I think it is great and somewhat easy to understand. How can I use a pre-made brd file to use with my schematic? A friend designed a brd for me to use as I design some audio gear and need to use his board size and layout for it to work. Can’t ask my friend anymore as he had passed away awhile back.

any help would be much appreciated.

thank you.

Group rotate doesn't rotate polygons

alberthall — Wed, 17 Feb 2021 15:27:47 GMT

Eagle 7,6,0

I have a board layout which I want to rotate 90 degrees so it will fit on my CNC machine.

I use group on the whole board layout, then rotate. Everything is rotated except polygons which stay where they were.

How do I get the polygons to rotate with the rest of the board, please?

Adding an Arduino Nano into a schematic

dubbie — Tue, 22 Dec 2020 17:14:43 GMT

How do you put a Nano into an Eagle schematic?

I have used other schematic capture softwares a few years ago so know the general idea. The one I used had Nanos as a component so that it could easily be added. I have just started to use Eagle and want to make a PCB that mostly just contains a Nano and a couple of other components. But I do not seem to be able to find out how to do it. Can you help?

Looks like you use windows. Unfortunately you didn't tell which version.

In newer versions of windows there are user "groups", means that your

path could be something like

C:\USER (your name)\eagle etc.

Check that out first, then check if you can reach your program via CMD,

to verify that the complete path is correct.
