getting highlighted upon cursor approaching. If you then click , a node will be created, and the
tolerance annotation element snap to it.
A 2D node created using any-type snap can be free (not maintaining a relation with the elements
based on which it was constructed, after the creation) or constrained (tied) - where the node relation
with the source elements is maintained.
When using snaps to a construction line intersection, a circle center, end points of graphic lines,
defining points of drawing annotation elements (dimensions, leader notes, roughness symbols,
tolerances), as well as 2D fragments – then constrained nodes are always created.
When using all the rest snap types, the state of the auto parameterization mode is significant (the
icon on the system panel). If the auto parameterization mode is enabled, then a constrained
node is created. With the auto parameterization mode disabled, either a free node is created, or a
point with appropriate coordinates (when creating a leader note, roughness, tolerance, cropped
view symbol and 2D fragments).
The buttons [Increase Priority] and [Decrease Priority] serve to modify the priority of
object snaps. Snap priorities determine, in what order the system will be offering them to the user in the case
when several snap possibilities are found. The list “Enable snaps to” has the snaps positioned in the
decreasing priority order.
For example, snapping to construction lines has higher priority then “Vertical/Horizontal” snapping (this can
be seen by their position in the list). Therefore, when constructing 2D elements using snaps, the system will
first offer the user snapping to construction lines, and only after that - snapping to vertically/horizontally
aligned nodes.
“Windows” Tab
Use double buffering on redraws. This flag sets the
double buffering mode for redrawing 2D document
windows that enhances perception of redrawing by
removing flickering.
Halftone Bitmap Drawing. This option turns on the
halftone mode of displaying bitmaps: raster pictures,
inserted into T-FLEX CAD documents, ray-tracing
results, etc. By default this parameter is turned on.
“When new windows are created” group of parameters
defines the following modes:
Create Scrollbars. If unset, the scrollbars will not be
created, and vise versa.
Create Rulers. Similar to the previous, if unset, the rulers are not created on opening the window.
