Drawing in Creo Schematics

I am new to Creo Schematics. I went through the LMS tutorials and got 94% on the assessment.

Now, I'm trying to generate my first live schematic. I have the library of IEEE symbols from Virtual Interconnect. Many interesting components, unfortunately, I need to do diagrams for wiring harnesses and 90% of what's in that library doesn't work for me.

So, I want to draw my own circuit symbols. We won't be using wiring diagrams as such.

My first attempt was to make a symbol for a double fuse holder as a group so I could place the two sections anywhere. TO do this, I need to place two arcs to make the fuse shape.

Neither of the two arc selections in the geometry tab seem to work. I get an error "Operation only valid in EDIT mode" when I try to draw. I can draw lines and boxes all day without errors.

Does anyone have a link to a true tutorial on how to draw in Creo Schematics? THe on-line tutorials are sorely lacking in details of how to do things from scratch. Making sheet templates with a company logo should be easy - once you are shown the secret.

Also - I have looked and looked for a book - actual paper pages in a binding - on Creo Schematics. I have found a few on Creo 2.0, concerning 3D model creation, but nothing for Schematics. Any suggestions? In particular, I want something that explains which parameters are critical in Schematic to link with Creo 2.0 cabling.

*.she file are design database files and should never be moved, deleted or accessed via windows explorer

I am assuming the design you can access the library in is called IEEE_315_1975 V1_1_2.

You have two options

Option one is submit the catalog to a central location and then point all new designs to the central location. For now i do NOT recommend you do this until you have completely setup your template design.

Option two and the one i recommend for now is to
Open design IEEE_315_1975 V1_1_2
Click file export Design properties - this will export your design properties and all the catalog to an itermediate file
Open your new design
Click file import Design properties
Choose the exported file from step 3
Follow the prompts

Your catalog should now be available in your new design

Let me know if that does not work, thanks, Jim

Thanks, Antonius. I hope someone has the answers I need - time's a wastin!

While I'm asking for help, regarding that Virtual Interconnect library. I opened my current design via "Create New Design", and it did not link to the Virtual Interconnect library - it gave me a blank workspace. I can't figure out how to include that library in this workspace. If I could get into it, I could recover some fiber definitions I did while I was learning, and perhaps find symbols that i could use. Unless I open a new project with "Autogenerate new Design", I can't see the original library selection.

Chuck; since I am assuming you are a maintenance customer with a relatively new software purchase, you also have access to technical support. If you have not yet signed up for your support features, please take the time to do so. We often have challenges between the forum and customer support to see who can answer first and who is actually right.

There are no dumb questions as to getting PTC support. Just log the case and they will get back to you. That is why we pay the big bucks

Welcome Chuck, I use schematic for piping (P & ID) application. However you also find many person for eletrical application in this forum. I guess you need to proceed for creation of block there only the geometry tool will work. Apart from tutorial if you ask any specific question, I guess I can help you with my limited knowledge in RSD.

Hello Chuck,

Regarding your first issue (drawing arc)

If you didn't done it yet, i recommend you to practice Creo Schematics tutorial (in Get started tab->Training->Tutorial)
Creo Schematics include very helpful help center, just search for arc and the first topic will be 'To Create Arcs'. when you need help on some issue - I recommend you to start in the Help Center, there is high probability you will find answer/example there. (File menu->Help->Help Center)
In general - all edit line tools require to be in edit line mode which can be done by :
- during draw of line :Click Line and select a line tool->Click a start point on the sheet -> use the edit line tools
- double left-click on the line will enter into edit line mode -> use the edit line tools

Regarding the 2nd issue (Virtual Interconnect library):

since i don't know how this library is provided, you need to do one of the following :
- use the template (*.rsd file) provided by Virtual Interconnect while creating new design
- link your design to central catalog (if exist) provided by Virtual Interconnect
in the help center, review the topics :
- 'To Create a New Design'
- 'About Central Catalogs'

Gaby.

Hi, Gaby,

I've gone through the tutorials - they show how to recreate things that already exist, but no details on how to make them from scratch. I got 94% on the online training, but again, little information on the details of how things work.

For instance - 'edit mode' - how do I get into it? I could not draw an arc, as I related before, but lines are easy.

Yesterday, I was poking around in the admin tab, trying to find how to access the purchased library. I must have done something, because now I can see the blocks I drew in the catalog explorer, but when I try to edit them I get the error 'Cannot edit shape for central catalog item'. How do I re-enable editing?

I can use the template from the library - but it brings up a sheet with the Virtual Connect logo, and I can't figure out how to edit that. We have Pro/E and a full set of templates with our company logo - but how do I access them?

So many small details that aren't in the tutorials, but should be in a reference book. I have good reference books for Autocad and my PADS and Altium PCB layout software, but nothing is available from PTC.

On page 42 of the tutorial that is available from the get started tab there is all the steps on how to create a new port shape from scratch.

From page 47 a block from scratch - on page 49 step 28 it will tell you how to edit a line.

From Page 51 a variable group from scratch.

After completing these exercises you should have all the basic information on how to create to catalog items, so I am afraid I do not understand you comment about how to recreate everything that already exists and no details on how to make them from scratch.

Re the central catalog have you read the help topic Working with Central Catalog. In this topic it states After an item has been incorporated into the Central Catalog it is locked automatically and only an editor can edit it. The administrator sets a password for the design that the editor uses to unlock for editing. So what this is saying is the design needs to have a password, which will allow you to unlock the catalog and make changes.

On page 32 of the tutorial there is step by step instructions on how to create a drawing template and how to import existing design sheet templates / logos.

I have also created a video which shows different methods of creating arcs.

I hope all the information helps

cheers, Jim

I agree that it would be great to have a book that covers some of the basic areas in Schematics, like drawing items. The program is massively complex and allows a lot of different types of uses, so no book can be anywhere near complete except in particular areas.

Even with a consultant helping us, she really only had time for the critical major items like design philosophy and teaching me (the administrator/editor) how to work with the data tables and minimal teaching on how to draw components. I am doing a lot of learning on my own and hitting her with questions I cannot discover the answer to. She also spent about 16 hours doing training classes for the users which covered most of their work and how to attach to different libraries.

The items in the Edit Line section of the Geometry tab only work after you have started a line. Click on Line, then the start point, then on Arc. It will prompt you to click on the end of the arc and will then rubberband the arc while you choose the centerpoint of the arc.

-To draw your fuse:

click on line

draw the straight segment (if you are using one)

click on Arc

click on the end of the first arc

if it is not creating the arc in the direction you want, right click and select flip

click on the center of the arc

repeat that group of instructions for the other half of the fuse and the remaining straight line.

There is a lot of experimentation needed and I still need to do a lot of it myself.

I am just getting things ready for the guys that are about to do their first schematics.

----------

We were ready to buy one or more of the libraries from Virtual Interconnect but determined that none of them gave us much created that we could use. They obviously must work for some groups, just not us.

I worked with the harness designers to develop some basic standards for how our new symbols would look and am drawing our own symbols so that they are consistent for spacing, size, and other style items.

We are using a hybrid design model for Schematic instead of a true schematic and a plain wire connection diagram. The one drawing will do the work of the schematic and the wiring diagram with each harness layer being used for export for routing them.

We are creating symbols for every part that we use in our circuits as groups with the mating connectors already attached. The resulting drawing looks like a schematic but there are individual wires that go to splices instead of networks that could be connected anywhere.

Arcs for fuses

Late reply - hopefully you already found out how the arc works. Not well documented.

The items in the "Edit Line" section of geometry only work once you have started a line.

I tend to try to make my symbol graphics in one line if possible so that I can move them easier when I want to reuse things like switch or relay parts.

To draw your fuse: (what I do)

Start a line. If you want a straight section connected to the arcs, place it but do not end the line.

Click on the center point arc command.
Select the far end of the arc and the center point.

Click on the center point arc command, right click and select flip.

Select the far end of the arc and the center point.

Continue with more line segments as needed for the symbol.

The other command in that group that I use regularly is Segment Visibility. Very useful if you have a symbol that cannot be drawn with a connected line (like the ground symbol).

Draw a segment to move to the beginning of the next line and click on Segment Visibility. The segment you just drew disappears but the disconnected visible segments remain part of the same line.
