软件适合钣金工、铆工、白铁工、管工以及从事机械制造业的工程技术人员使用,提供了一百多种展开样式,并且能生成带真实尺寸的高清展开图。 软件特点: 用计算的方法来求得被展体展开所需要的各素线实长。这种展开方法有以下几大优点: 1.由于计算展开不需放大样,省去了传统展开需要放样场地的烦恼,如果被展体较大,更能体现这一优势。 2.用计算方法展开,不但便捷,而且速度快,只需几分钟就能完成。 3.用计算方法展开不但速度快,而且精度高。软件计算不但计算结果精度高,而且正确率也高。 软件按统一UI界面排布,具体式样如下: 1.已知条件指图样对被展体的形状、形态、角度以及长度等所标注的有关尺寸数据。 2.所求对象指被展体展开必须要求出的各有关素线名称。 3.过渡条件指为求被展体各有关素线实长,又不能直接求出而必须要的中间辅助条件所列计算公式。 4.结果计算指为求被展体各有关素线实长,所列出的各相对应的计算公式。 5.注解及说明指为使读者能更好地理解公式,对所列计算公式中的有些内容,所给出的必要解释和说明。 6.配图指为使读者能清楚直观地了解被展体,插有立体图、视图,并对被展体形状、形态、位置、角度等,用字母代号标注。而且还插有展开图样和相贯体的开孔图样,这些同样也用相应的字母代号表示各展开素线。 软件包括如下大类的钣金展平样式:方形管锥台、方形管弯头、方形管(三)多通、圆形管锥台、圆形管弯头、圆形管(三)多通、方圆过渡锥台、方圆过渡(三)多通、不可展曲面、相贯体。 【VIP会员连续包月说明】 订阅周期:1个月(VIP会员连续包月);3个月(VIP会员连续包一个季度);6个月(VIP会员连续包半年);12个月(VIP会员连续包年)。订阅价格:以iAP申请信息为准,例如连续包月为每月6元;连续包半年为每六个月28元;连续包年为每年50元。 付款:用户确认购买并付款后记入iTunes账户。 取消续订:如需取消续订,请在当前订阅周期到期前24小时之前手动在iTunes/Apple ID设置管理中关闭自动续订功能。 续订:苹果iTunes账户会在到期前24小时内扣费,扣费成功后续订周期顺延一个订阅周期。 隐私政策:http://www.agicloud.com/file/privacy.html 用户及会员协议:http://www.agicloud.com/file/member.html 自动续费服务规则:http://www.agicloud.com/file/auto_renew.html
