Dynamic Snap with Object Snap off

Issue

Dynamic Snapping does not work if Object Snap is turned off in the Layout menu > Drawing Setup > Snap Tab. This condition is the opposite to how things worked in PowerCADD 6 and earlier.

Affects

PowerCADD v7.00, v7.0.1 in Mac OS? X



Description

In previous versions of PowerCADD (that is prior to PowerCADD v7), the user could force an object snap to occur by pressing the associated key command, even when Object Snap had been turned Off in the Layout menu > Drawing Setup > Snap Tab. This was a helpful feature since it allowed automatic snapping (which is what occurs when Object Snap is On to be turned off in crowded drawings but still gave the user complete manual control over the dynamic snapping process.

In PowerCADD v7, turning Object Snap off completely disables object snapping entirely for the specified drawing. This condition is contrary to how it worked in PowerCADD v6 and earlier

To See the Correct Condition

In PowerCADD v6 and Mac OS X, do this:

  1. Create a New Untitled document
  2. Draw an object
  3. Choose Layout menu > Drawing Setup > Snap tab, uncheck the Object snap box, and click Ok
  4. select the Line tool and try to perform an End snap by pressing the E key and putting the mouse over the End Point of the object drawin in (1)
  5. Observe: the new line is drawn and snapped precisely to the end point of the existing object
  6. This is a correct result

To See the Incorrect Condition

In PowerCADD v7 and Mac OS X, do this:

  1. Create a New Untitled document
  2. Draw an object
  3. Choose Layout menu > Drawing Setup > Snap tab, uncheck the Object snap box, and click Ok
  4. select the Line tool and try to perform an End snap by pressing the E key and putting the mouse over the End Point of the object drawin in (1)
  5. Observe: the new line is not drawn from the precise end point of the existing object
  6. This is an incorrect result

Work Around

One work around is to keep object snap on for all drawing situations. While this is typically the default condition for the vast majority of drawings and users out there, it could be a production slow down for some users who typically ran with object snap off in previous versions of PowerCADD.

The second option is to use a new PowerCADD v7 feature and turning Layer Snap Off for the desired layer[s] thereby reducing the number of objects that PowerCADD will automatically snap to in a crowded drawing.

This issue has been reported to Engineered Software by PowerCADD Canada.

FIXED in PowerCADD 7.02

This issue is fixed and performance is GREAT in PowerCADD 7.02

If you're using PowerCADD 7.00 or 7.01, update your copy of PowerCADD and your problem should be fixed!

A third work around:

A third work around:

A third option, as suggested by PowerCADD Canada by email, is another good one. Leaving Object Snap On, but setting the Snap Distance to it's minimum value of 2 pixels, might be a practical solution for some drawing conditions.

To adjust the Snap Distance Setting, do this:

  1. Choose PowerCADD menu > Preferences... Tools tab
  2. enter a value of 2 (the minimum allowable value) in the Snap Distance field and click OK

That will require the mouse to be 2 pixels (as compared to the default of 9 pixels) from an automatic snap before it's envoked.

We understand from

To the best of our understanding, the feature/problem discussed in this article is no longer supported in PowerCADD v7.

When the new PowerCADD 7 feature to permit turning snapping on or off per layer was introduced, support for the old feature (as described in the body of this article) appears to have been abandoned for internal programming issues.

If we get any additional information related to this known issue we'll report it here.
