# Linetype Manager Dialog Box [GstarCAD 2023](Help%20System/GSTARCAD/2023/Index.md) → [Commands](Help%20System/GSTARCAD/2023/Commands/(Commands).md) **Function Description:** Loads, sets up and modifies linetypes.  **Dialog Box Options:** ## **Linetype Filters** Determines which linetypes to display in the linetype list. Users can filter linetypes according to the following ways: whether they are dependent on Xref or whether they are referenced. - **Invert Filter:** Displays linetypes by specifying the opposite conditions. The linetypes which fit the inverse filter conditions  are displayed in the linetype list. ## **Load** Displays the Load or Reload Linetypes dialog box. Users can select a linetype from the gcadiso.lin file and add it to the linetype list.  ## **Current** Sets the selected linetype to be the current linetype. Setting the current linetype to BYLAYER, it means the objects are created by the linetype of a specified layer. Setting the current linetype to BYBLOCK, it means the new created object uses the CONTINUOUS linetype until forming a block. No matter when inserting a block, objects in a block inherit the linetype of a block. The linetype name is saved in the CELTYPE system variable. ## **Delete** Deletes selected linetypes from the drawing. Users can not delete the linetype of BYLAYER, BYBLOCK and CONTINUOUS. Only unused linetypes can be deleted. **Note:** If the drawing is created by a shared project or based on a group of layer standards, users should be more careful when deleting linetypes in the drawing. The deleted linetype definitions are saved in gcadiso.lin file, users can reload them. ## **Show Details or Hide Details** Controls whether to display the details of the Linetype Manager. ## **Current Linetype** Displays the current linetype name. ## **List of Linetypes** Displays the loaded linetypes according to the option specified in Linetype Filters. - **Linetype:** Displays names of loaded linetypes. Selecting and double-clicking the linetype name can rename it. The following linetype can not be renamed: BYLAYER, BYBLOCK,CONTINOUS and Xref dependent linetypes. - **Appearance:** Displays the appearance of selected linetypes. - **Description:** Displays the description of the linetypes. ## **Details** Provides another way to access to properties and additional settings. - **Name:** Displays the name of the selected linetype. Users can edit it. - **Description:** Displays the description of the selected linetype. Users can edit it. - **Use Paper Space Units for Scaling:** Scales linetypes in paper space and model space identically. It is useful in multiple viewports. (PSLTSCALE system variable) - **Global Scale Factor:** Displays the global scale factor for all linetypes.(LTSCALE system variable) - **Current Object Scale**: Sets linetype scale for newly created objects. The regenerated scale is the multiply of the global scale factor and the scale factor of itself. (CELTSCALE system variable) - **Iso pen width**: Sets the linetype scale to be one of a list of standard ISO values. The regenerated scale is the multiply of the global scale factor and the scale factor of itself. --- [Original help](https://www.gstarcad.net/help/GstarCAD_2023_en-US/detail/commandReferences/LINETYPE_DIA.html) · © Gstarsoft Co., Ltd.
