I would like&nbsp;subdivide all of the intervals into smaller increments, say 2 or 5 or 10 meter intervals. I have used the Generate Points Along Lines tool and get very inconsistent results, or it locks up Pro or Pro crashes. See attached layer package.</P><P>Thanks</P> Fri, 30 Jan 2026 11:39:49 GMT https://community.esri.com/t5/3d-mapping-questions/need-to-subdivide-vertical-polylinez-into-smaller/m-p/1681009#M1210 JohnEsch2 2026-01-30T11:39:49Z Re: Need to subdivide vertical PolylineZ into smaller intervals https://community.esri.com/t5/3d-mapping-questions/need-to-subdivide-vertical-polylinez-into-smaller/m-p/1681033#M1211 <P>are you using</P><P><A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/data-management/generate-points-along-lines.htm" target="_blank">Generate Points Along Lines (Data Management)—ArcGIS Pro | Documentation</A></P><P>or</P><P><A href="https://pro.arcgis.com/en/pro-app/latest/tool-reference/3d-analyst/generate-points-along-3d-lines.htm" target="_blank">Generate Points Along 3D Lines (3D Analyst)—ArcGIS Pro | Documentation</A></P><P>What do you mean by inconsistent results?</P> Fri, 30 Jan 2026 09:59:11 GMT https://community.esri.com/t5/3d-mapping-questions/need-to-subdivide-vertical-polylinez-into-smaller/m-p/1681033#M1211 DanPatterson 2026-01-30T09:59:11Z
