I am having a problem with grid snapping in block diagrams

 

When a new block is added to the drawing, I can connect to the connectors via a cable or dogleg with no problems, however, it seems that these connectors are just slightly off grid.  What can I do about this?  It causes drawings to look a little funny when the attachment point is almost on the grid, but not quite.

 

Thank you for your help in resolving this quickly.

I am currently using English Units of measurement for the grid spacing.

The attachment shows the problem that I am encountering.

 

Upon a fresh install, it seems to work as it should for approximately 10 drawings.

Hi Jerry,

Check that the Grid and Nudge values in your document are 2.5mm:

  1. Select Options | Preferences | Millimeters
  2. Check that Options | Preferences | Precision is set at 1 decimal place or more
  3. Display the Document Properties sheet (doubleclick anywhere on the document, or rightclick and select Document) and check the Nudge value in the Dimensions tab and the Grid Spacing values in the Grid tab

If the values are not 2.5mm you should check/edit the template which can be found under the Stardraw installation folder at \Templates\Block Schematic.S01

Please post again if this does not resolve your problem

Regards

Rob

I'm having a similar problem.  If I have to draw a few horizontal cables, the top one will be straight but others are a little jagged.  This happens with symbols from the libraries.  I've played with various grid and nudge values.

Thanks,

Lance

Hi Lance,

Can you confirm that Snap to Grid is on?

If you'd like to reply attaching a drawing that exhibits the problem, we'd be happy to look at it and post a solution.

Kind regards,

Yes, I've tried several snap methods sucha s snap to intersection and snap to connector.  Attached is a simple drawing to illustrate the problem.

Thanks,

Lance

Hi Lance,

That's the problem - you have turned Snap to Grid off.

With Snap to Grid on, when you insert a symbol into a document its IO stubs will align exactly with gridpoints, and any connections you draw will align exactly to the IO stubs.

If you turn Snap to Grid off, symbols will never be on the grid, however carefully you position them.  This is why Snap to Grid is on by default when you create new documents based on the default Block Schematic template.

I hope this is helpful.

Kind regards,

Well, both of these components were placed with snap to grid on.  Just to be sure, I deleted them, made sure snap to grid was on, placed the components and redrew the cables.  Same problem.

Hi Lance,

As posted earlier in the thread, you need to ensure the following:

Check that the Grid and Nudge values in your document are 2.5mm:

  1. Select Options | Preferences | Millimeters
  2. Check that Options | Preferences | Precision is set at 1 decimal place or more
  3. Display the Document Properties sheet (doubleclick anywhere on the document, or rightclick and select Document) and check the Nudge value in the Dimensions tab and the Grid Spacing values in the Grid tab

If the values are not 2.5mm you should check/edit the template which can be found under the Stardraw installation folder at \Templates\Block Schematic.S01
