Get content text of an attached Attrib entity with Get_attrib_text ( tag : str, default : str = '', search_const : bool = False ) → str ¶ Some applications do not attach constantĪTTRIB entities, set search_const to True, to get at least the Get an attached Attrib entity with the given tag, Get_attrib ( tag : str, search_const : bool = False ) → Optional ] ¶ Search_const – search also const ATTDEF entities Search_const to True, to check for an associated AttDef entity Some applications do not attach constant ATTRIB entities, set Returns True if the INSERT entity has an attached ATTRIB entity with the Has_attrib ( tag : str, search_const : bool = False ) → bool ¶ Spacing – distance between placing as (row_spacing, column_spacing) tuple Size – grid size as (row_count, column_count) tuple Row- and column count, spacing defines the distance between two block Place block reference in a grid layout, grid size defines the Grid ( size : tuple = (1, 1), spacing : tuple = (1, 1) ) → Insert ¶ Scale – (x-scale, y-scale, z-scale) tuple Insert – insert location as (x, y ) tuple Set the location, scaling and rotation attributes. place ( insert : Optional = None, scale : Optional ] = None, rotation : Optional = None ) → Insert ¶ Returns the multi-insert count, MINSERT (multi-insert) processing Returns True if the scale factor is uniform for x-, y- and z-axis, Returns True if scaling is applied to any axis. column_spacing ¶ĭistance between two insert points (MINSERT) in column direction (float) attribs ¶Ī list of all attached Attrib entities. column_count ¶Ĭount of repeated insertions in column direction, MINSERT entity if > 1 (int) dxf. row_spacing ¶ĭistance between two insert points (MINSERT) in row direction (float) dxf. row_count ¶Ĭount of repeated insertions in row direction, MINSERT entity if > 1 (int) dxf. Not all CAD applications support non-uniform scaling (e.g.

Scale factor for x direction (float) dxf. Insertion location of the BLOCK base point as (2D/3D Point in OCS) dxf. To improve legiblity, make corrections, or make adjustments after scaling a drawing, dimension labels, dimension lines and extension lines can be repositioned using Entity Handles.ĭimensioning drawings is beyond the scope of the LibreCAD User Manual, but additional resources and examples are available in LibreCAD’s wiki or elsewhere on the web.Do not instantiate entity classes by yourself - always use the provided factory functions! class ezdxf.entities. Use arrow heads or slash marks at the end of the dimension lines.Multiple lines of dimensions are spaced uniformly with a minimum of 6mm / 1/4” between dimension lines (see note above).Extended a circle’s or arc’s center lines and use as extensions line when possible.Center lines or center marks should be used on all circles and arcs.Dimension circles with diameters and arcs with radiuses.Except for large circles and arcs, all dimensions should be placed outside the part and spaced 10mm / 3/8” from the entity.When there are multiple lines of dimensions, the longer dimensions are to be placed outside of shorter ones.A dimension should be referenced to a logical origin point.There should be no need to calculate or scale a dimension of an entity.Each entity on the drawing should be dimensioned and dimensioned only once.The view that best shows an entity is the view that should be dimensioned.Provide space between dimensions to ensure legibility.Extension lines and entity lines should not overlap.Dimension and extension lines should not cross.There should be only one way to interpret any one dimension.
