Grids, Pen en Snapping

SkyCiv’s goal is to shorten the time spend modelling your structure with the institution of useful functions in S3D. The following set of mouse click functions facilitate this goal by streamlining the modelling process.

Er is een scala aan tools waaruit u kunt kiezen. These can be accessed by clicking the pen icon to launch the following great tools:

Klik op het penpictogram om toegang te krijgen tot de raster- en snapopties


Grids can be toggled on to show reference lines anywhere in the model space. You can use grids in conjuncture with the draw tool very effectively here:

There are a number of controls for the user-defined grid:

  • Plane SelectorThe grids have been simplified into these three toggle buttons for each 2D plane (XY, XZ, and YZ). Click that plane to toggle it on and off.
  • Start PositionThe position in the 3D space at which the grid will start at. Use this to pan/move the grid to a position that makes sense for you to work from. In the right (en hoger) voorbeeld, the grid starts from the reference point (0,0,-10).
  • Grid SizeThe size of each small square of the grid. In the right (en hoger) voorbeeld, each small square is 0.5m x 0.5m.
  • Level HeightBy what distance would you like to replicate the grid up? In the right (en hoger) example there is only 1 level, so level height is not applied.
  • Number of LevelsHow many times would you like to replicate the grid up? In the right (en hoger) example there is only 1 level.

With the draw tool toggled on, users can hover over any point on the grid and plot a node. If the setting Show Coordinates onder Snap Options is ticked on, it will show the coordinates of that grid position, so you know where the node will be positioned.

Pen tool and Snapping Options

Snapping is an easy way to plot nodes and generate members using the pen tool. Simply hover (or click) a node to define this node as being the reference point. Then move your cursor along the global X, EN, or Z-axis and it will snap to that axisshown as a dotted red, green, or blue line depending on what axis is being snapped. The snapping tool might also pick up a secondary axis, such as an alignment of another node. To disable that reference node, simply click somewhere that is not snapped or hit Esc.

Here is an example of the pen tool snapping to the global Z-axis, with reference to node 2. It is also picking up a secondary axis of node 5’s Z coordinate:

  • Beweeg of klik op een knooppunt, this will become your Referentieknooppunt, from here you can use the Snap/Grid to plot a node:
  • Met de Lid verbinden tick-box selected, je kunt zowel een knooppunt neerzetten als de knooppunten verbinden als lid:
  • Snapping will also detect a secondary axis. Bijvoorbeeld, if you’re traveling across the X-axis of a node, it might pick up other nodes with that same X-axis.
  • Het vak Lengte geeft automatisch de lengte van de afstand vanaf het referentieknooppunt weer (and hence the length of the member). At any point you can enter a length and hit Enter, or click, to apply that member length.
  • Enter a length and click the (lock) icon to lock the length. Now you can create members fixed at this length.
  • Snap to a member’s midpoint

The snapping options

  • Snap OnToggles the snapping on and off
  • Show Distance Labelif this option is ticked on it will show the distance of the proposed node from the point of reference (in most cases the length of the proposed member)
  • Show CoordinatesShow the coordinates of the proposed snap node.
  • Snap SizeWhat increments would you like the snapping to occur from the point of reference.

Snap Size Control

De snap size attribute will directly modify the size of the structure that is being displayed in order to make it easier for the user to snap to the correct increments. Bijvoorbeeld, a small snap of 5 mm will shrink the model down to a size that makes this easy to work with. This can be controlled at any time and is useful to control the following behavior:

A very small structure with a large snap size

This can be fixed by reducing the snap size
