Entity grips & osnaps

The efficiency of landscape design drafting can be improved by understanding how to edit a drawing using grips. Every entity placed in a gCADPlus landscape drawing has several defined snap points. When the entity is selected, these grips are blue-colored squares located at strategic points on the entity. Editing commands such as move, copy, rotate, join, and more can be done without the need to call the command from a toolbar or drop menu item. This dramatically improves efficiency.

Tip: If you cannot see the grip (handle) when an entity is selected, it is possible the grip visibility (display) has been turned off. This sometimes happens without a user’s awareness.

 Every entity placed in a gCADPlus landscape drawing has a number of defined snap points. For example, it is easy to jump to the mid or end point of a line, the center of a circle or the center of an arc. These points are indicated by ‘handles’ or ‘grips’ that vary according to the type of entity. The figure below that shows many of the ‘primitive’ entities in gCADPlus and their respective handles (or grips).


Entity snaps enable quick selection of exact points on existing entities without needing to know the exact coordinates of those points. You start a command – for example the LINE command, and select a start point(say) the end, then locate a destination point on a line, arc, the center point of a circle, the intersection of any two entities. The location does not even have to be an entity. Entity snaps can be used to draw entities that are tangential or perpendicular to existing entities.
The following entity snap ‘jump’ points are available: Center, Near, End, Mid, Node (Point), Quadrant (Grip), Tangent, Perpendicular, Near, Insertion, and Intersection

The required entity snap is usually selected from the osnap tool bar each time it is required. However, an alternative, and much more
efficient method when asked for a ‘to point’ is to simply right click and choose ‘snap overrides’.

More on grips.

Snapping to the quadrant of a circle – the Grips option

It is not immediately obvious, but the grips osnap option allows snapping to each of the four quadrants of a circle (or part of a circle – an arc).

Running osnaps vs. one time osnap

Beginners usually choose a single ‘one -off‘ selection. However, there are times when you will want a snap selection to stay active;. In
this case, set a running osnap. The Drafting Settings dialog box – the osnap tab – can be used for that purpose. To activate it, right click in the drawing editor and select drafting settings and the osnap tab.

To set a running osnap, select the first tick box – “Object snap on“, then select the required osnap – end, int, node etc.
The F3 function key is a toggle for switching running osnaps on or off.

Tip: Try and minimize the number of option boxes you tick. If you run with a lot of snap options on at the same time, the software will spend far too much time hunting for handles on elements in the drawing. This is particularly a problem in crowded areas of the drawing. You may well find that the to point is not where you expect it to be, simply because the software has jumped to a handle that you did not see.
