国产篇 cad问题小百科_Gcad

一些桌子的问题移步去: cad问题小百科_Acad (浩辰可能和桌子具有相同的问题,所以建议你也去看)

若大家对以下问题有更好的解决方案,可以评论中用 #20071编号 的进行评论,以便更好沟通~

#101 命令执行优先级

系统变量: autocompletemode,19

原因是"输入按键时显示建议列表"这个项打钩了,这里首先捕捉的是lisp定义的命令,而不是pgp.

#102 鼠标跳动

系统变量: Dynmode,0

动态输入,这个参数将导致zoom缩放的时候,鼠标会发生跳动,并有一定几率停留在边界.

一定要多用zoom测试,即使不设置这个参数也是有一点几率发生鼠标跳动,只是设置了更容易看见这个问题,并且会产生停留.

#103 gcad.net选择集参数有误.

gcad2019已经解决

//定义选择集选项
      PromptSelectionOptions pso = new PromptSelectionOptions
      { 
          // SingleOnly = true,                //不需要空格确认,但是浩辰会变成鼠标单框
          SelectEverythingInAperture = true,   //鼠标单框
      };

#104 gcad.net组块问题

将导致图元出现不可选择的问题..

这里是一个很严重的问题,我的习惯是先生成图元到内存中,然后进行矩阵移动,最后再添加到数据库内.

acad是允许这样操作的,这样操作也很符合常规思维,

如果不能修复这个问题,那么将要先计算好再生成或者先生成到数据库再进行矩阵变换,

前者编程思维要改变,代码改动很大,后者用户操作时候会发生卡顿等.

#105 gcad.net新建文字样式

gcad与acad在这个地方不同的是新建文字样式的时候如果用到.TTF字体,直接写字体名称就好了,不能够写"新宋体.TTF"不然浩辰出现以下情况:

看上去是乱码的一坨东西,和文字样式面板的字体名多了个.TTF.SHX(X)

而acad需要写".TTF".后缀名.那么此时是不是没有区分shx和ttf呢?

#106 gcad.net注册表

string KEY = HostApplicationServices.Current.RegistryProductRootKey; //这里浩辰读出来是空字符串

#107 gcad.net注册表

在net4.0及以上工程获取注册表会出现以下问题,而用这在net3.5是没有的..



要将代码改成以下获取:

var copys = Registry.CurrentUser.OpenSubKey(@"Software\Gstarsoft\GstarCAD\R19\zh-CN\");
var b = copys.GetValueNames();
foreach (var item in b)
{
     string sz = copys.GetValue(item).ToString();
     sz = sz.Remove(sz.IndexOf(''));
     Console.WriteLine(sz);
}
