In %PRODUCTNAME Draw, a dimension line is always inserted on the <link href="text/sdraw/guide/layer_tipps.xhp">layer</link> called <emph>Dimension Lines</emph>. If you set that layer to invisible, you will not see any dimension line in your drawing.
%PRODUCTNAME Draw aplikazioan kota-lerro bat beti txertatzen da <emph>Kota-lerroak</emph> deitutako <link href="text/sdraw/guide/layer_tipps.xhp">geruzan</link>. Geruza hori ikusezin bihurtzen bada, ez dira ikusiko marrazkiko kota-lerroak.
