210 Pa. Code Rule 2134 – Drafts or Plans.

(a) General rule.—All maps, plans and drawings used on appeal must conform to the provisions of this rule.
(b) From the record.—When on the trial or hearing in the court or other government unit below, there is offered in evidence a draft or plan, which would be of assistance to the appellate court to enable it to understand readily the dispute between the parties, a copy thereof shall be attached to the brief of the appellant, or filed therewith, folded the same size as the brief.
(c) Prepared specially for argument.—If a draft or plan is not contained in the record, but would be of assistance to the appellate court as prescribed in Subdivision (a) of this rule, a simple draft, plan or sketch, made by or for the appellant, folded to the same size as the brief, shall be attached to or filed with the brief of the appellant, marked so as to show it was not part of the record. Under like circumstances, the appellee may prepare and attach to or file with the brief for the appellee a draft, plan or sketch made by or for the appellee. Either party may point out, in his brief or reply brief, wherein he considers the one presented by his adversary not to be correct.
Official Note
Based on former Supreme Court Rule 40 and extends the provision to the Commonwealth Court. Former Superior Court Rule 32 was similar to Subdivision (b), but provided that the draft or plan was to be attached to the reproduced record. See also Piper v. Queeney, 282 Pa. 135, 147, 127 Atl. 474, 479 (1925).
