Your palm is correct. You don’t need to drill a hole. View post on imgur.com 2016-03-05 at 4:19 pm #781 Hiroshi YamauraKeymaster I recommend you to use CAD just for assembling manual. You don’t need to edit 3D data. You can use it as 3D data viewer. It can be good assembling instruction. 2016-03-05 at 4:51 pm #785 EW CHEE GUANParticipant Hi Hiroshi, Thank you for your tips , Yes , Its more clear if I view the 3D CAD file . I can assemble now , Thank you! Author Posts Viewing 4 posts - 1 through 4 (of 4 total) You must be logged in to reply to this topic.
