Drawing in Creo Schematics

SOLVED

Re: Drawing in Creo Schematics

It worked. Now, I have the original Virtual Connect catalog. available in my design.

I also need to import the catalog data from other designs. My first attempt brought an error - "you cannot import design properties when there are protected layers"

Where do I find these layers and un-protect them? The design is an empty template and a catalog now.

If you cannot find a command use the search which in the top right corner

Re: Drawing in Creo Schematics

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.

Re: Drawing in Creo Schematics

Chuck, I guess by now you have a better picture of how Schematics work.

but still, it is complicate to create the drawings of your artifacts.it is a time onsuption if you want to draw something close to real life artifact shape.

I have a post where I am asking why it is not possible to import a 2D drawing created in CREO PARAMETRIC direct to Schematics?

I work on CREO PARAMETRIC and I can easily draw or download the 3D of my terminal block, sofstarter, braker, deustch connector, amphenol connector, SSR and so on, then I can create a 2D of it but if I want to use it in Schematics I have to convert it to DXF then import it in Schemtics.

it is like Hello guys you work for the same company your product is an extension of their product why not make them more compatible?

of course there is a way, but you need to buy another module to interface Parametric with Schematics which makes the total investment more expensive just to be able to share simplethings.

I understand bussines is bussines but still does not make sense.

So if someone in your company works with CREO PARAMETRIC just ask to Download the 3D of the part, generate the 2D and export in DXF so that you can import it in Schematics.

I hope this gives you another viewpoint

Re: Drawing in Creo Schematics

Antonio: Creo Schematic is not in any way related to Creo Parametric other than being owned by PTC. It was written by another company (Quintic) and based on a mechanical CAD program (the line types are from it) called Medusa.

http://en.wikipedia.org/wiki/MEDUSA

We just found out that we cannot link the live data for the diagrams and tables into our flattened harness drawings done in Creo Parametric like we could with Pro/Diagram.

I have found some real issues with bringing in DXFs.

- It appears that the DXFs made by our old schematic drawing software generated items that Schematics doesn't know how to handle. They become invisible items at intersections of lines or off in blank areas. You have to find them by selecting areas and seeing if handles appear so you can delete them.

- The DXFs also came in as individual line segments rather than complete lines.

We decided to just use the drawing tools (it takes some discovery to find out how they work since there are no instructions anywhere) to redraw our symbols. I built up a sheet in my librarian drawing with some of the common items like contacts, coils, resistors, lights, diodes, labels, etc so that I can build up symbols faster by putting the parts together on a drawing page then copying them to the groupshape.

Since we are doing schematic symbols and not pictorials of the parts, drawing them in the Schematics editor is about as good as any other sketching program.

Way back when IBM PCs came with cassette tape interfaces for data, I was part of a local user group where I learned a lot about how pc's worked and how to make Lotus 1-2-3 really do good stuff.

Schematics doesn't have a large installed base like Parametric and it would be really useful to get together with other local people to swap knowledge.

Re: Drawing in Creo Schematics

Hi Jim,

I just found this posting, but quickly discovered that your references to the page numbers in the Basic_Tutorial.pdf are no longer applicable for v3.0, and actually some of the useful content (that I think you wrote) in the v2.0 Basic_Tutorial.pdf is now completely missing... .

Anyway, I've downloaded and unpacked the ZIP file (ptc19.cab) from the media for v2.0_M020 to extract the previous version of the Basic_Tutorial.pdf, and that does indeed show how to load the example "format.dxf" file provided in the <loadpoint>\Creo 3.0\M020\Schematics\creoschematics\basic_tutorial\DXF folder - so the same files still appear to be there in v3.0, but without any instructions on how to use them .   I see the v2.0 Tutorial also explains how to add Parameters to the Title block as well.

I understand that some of the terminology may be different between v2.0 and v3.0, but it is a shame that the newer documentation is less complete than the old copy.

That video was key to understanding how to make fillets. Thanks!

Re: Drawing in Creo Schematics

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.
