Organizing information on layers

Layers in progeCAD are like the transparent overlays you use in manual drafting. You use layers to organize different types of drawing information. In progeCAD, each entity in a drawing exists on a layer. When you draw an entity, it is created on the current layer.

You can control the visibility of layers in individual viewports. When you turn a layer off, entities drawn on that layer are no longer visible, and they do not print. Although a layer may be invisible, you can still select it as the current layer, in which case new entities are also invisible until you turn the layer back on. Entities on invisible layers can also affect the display and printing of entities on other layers. For example, entities on invisible layers can hide other entities when you use the Hide command to remove hidden lines.

You can also freeze and thaw layers. Entities drawn on frozen layers do not display, do not print, and do not regenerate. When you freeze a layer, its entities do not affect the display or printing of other entities. For example, entities on frozen layers do not hide other entities when you use the Hide command to remove hidden lines. In addition, you cannot draw on a frozen layer until you thaw it, and you cannot make a frozen layer current.

You cannot freeze the current layer. If you attempt to freeze the current layer, a dialog box appears prompting you to specify a different layer. You also cannot freeze or thaw a viewport layer unless you are working in a Layout tab.

You can lock or unlock layers. The entities on a locked layer are still visible and will print, but you cannot edit them. Locking a layer prevents you from accidentally modifying entities.

Each layer has its own color, linetype, and lineweight. For drawings that use named print styles, layers can also have their own print style. Entities you draw on a particular layer are displayed in the color, linetype, and lineweight associated with that layer unless you override these settings. You control all of the associated settings for layers using the Layers elements in the progeCAD Explorer.

To display layers in the progeCAD Explorer

Do one of the following:

  • Choose Settings > Explore Layers.
  • Choose Tools > progeCAD Explorer.
  • On the Tools toolbar, click the progeCAD Explorer tool ().
  • On the Settings toolbar, click the Explore Layers tool ().
  • Type explayers and then press Enter.

When Layers are displayed, three tools on the Layer toolbar provide the following functions:

() Layer On/Off Toggles the selected layers on and off.
() Freeze/Thaw Freezes or thaws the selected layers.
() Lock/Unlock Locks or unlocks the selected layers.

You can change any of these settings by clicking either the tool or its current condition. You can edit the color, linetype, lineweight, and other properties of a layer by clicking the corresponding name and selecting the values you want in the dialog box. You can also edit a layer’s properties by right-clicking it and choosing Properties.
