Can someone list for me all the steps involved in doing a middle-point snap?
There are at least three (maybe only three) different ways of executing a Snap
- SEKE: Single Equivalent Keyboard Entry-- Tap a particular key on your keyboard, and the Snap is executed (if your Snap Aperture is in such a location that the Snap invoked is possible. [Snap Aperture is made visible via Workspace|Cursor ])
- Local Snap: Available on the Local Menu by right-clicking on the TurboCAD desktop (again, a Snap is only possible if your Snap Aperture is in such a location that the Snap invoked is possible)
- Running Snap: The selected Snap(s) is/are active and will execute when the Snap Aperture is located such that the selected Snap(s) are possible.
Let's concentrate on Running Snaps
, assuming that is what you are normally used to using. There are a couple of fundamental settings you need to know about. Snap Settings
is available via Menu Bar/Modes/Snaps/Snap Options..., or by right-clicking on "Snaps" down at the bottom of the TurboCAD desktop.
In those Snap Settings:Show Magnetic Point...:
I don't know when it is ever
beneficial to not have this active. Leave it on until there is a very good reason not to.Priority:
This is how we set which type of Snap will take "priority" over another when the cursor's (Snap Aperture) position is such that more than one type of Snap is possible (example: You have a Line with another Line that intersects
very near it's middle-point. You have both the Middle-Point Snap and the Intersections selected as active. How does TurboCAD know which type of Snap to invoke? If Middle-Point Snap priority was set to "2", and Intersection Snap priority was set to "3", the Middle-Point Snap would take "priority")"In Aperture Only":
Another important setting. The best way to explain that is with an example: Let's say you have a Line. That Line has two endpoints... or Vertex-es (Vertices). Let's say you have only the Vertex Running Snap active. If-- when executing some sort of action while drawing; i.e.: inserting an Object or moving an Object-- you do not have "In Aperture Only" checked, and hover your cursor (Snap Aperture) over the Line, the Snap will occur automatically
to the nearest Vertex (endpoint) of that Line.
Conversely, in that same scenario, if you had "In Aperture Only" checked
, it is only when your cursor (Snap Aperture) is actually in a position such that either of the Vertex-es (Vertices) of that Line are in the Snap Aperture
will the Vertex Running Snap be executed.
I would say, for a semi-experienced User such as yourself, that is having issues with the Middle-Point Snap in particular, but generally knows how Snaps work, it is very likely that the "Priority" and/or "In Aperture Only" settings in the Snap Settings is the issue. Example: What if you have a Line. You have active both the Vertex Running Snap and the Middle-Point Running Snap. In the Snap Settings, Vertex Priority is set to "1" and its "In Aperture Only" is not checked
, and the Middle-Point Priority is set to "3". If you hover your cursor (Snap Aperture) over the middle-point of that Line, based on those settings, the magnetic-point and the snap will occur at the nearest endpoint (Vertex) of that Line.
Check and experiment with those settings. See if that helps you. I know you asked for step-by-step instruction on using the Middle-Point Snap, but that's really hard to do... because it's so basic. Activate the Snap and put the cursor in the middle of something. (remember, I'm limiting this lengthy contribution to Running Snaps; I'm not going into SEKEs or Local Snaps-- that's too much to cover in this one Post.)
