Dialogue box only shown top part

Hi,

I am using taskpane to show the dialogue box. It was all good before. After i added a few more labels and comboxes, it only shows the top half.

Is it need be changed in qt designer for some layout format to overcome this problem?

Regards,

John

在FC里玩python

FC自带了Python.你可以在它的bin目录里找到python的执行文件。在\bin\Lib\site-packages看到已经安装的各种python模块。 在win 10下,启动一种终端窗口,转到FC的bin目录里,在命令行里输入python,按回车键,你就可以玩一般的python了。 要在FC里玩,启动FC, 选View/panels/python console菜单确保python consol是打开的。在python consol里就可以一行一行地输入执行python命令了。比如输入help(),看看显示什么了。 help('modules')也可以列出安装的各种python模块。 ...

Re: Generate a truss and analysis with frame3DD

Depending what kind of obj this is in gmsh you export the objects from gmsh into unv (mesh) or brep (geometry). Both formats could be opened in FreeCAD. I am curious if this works. bernd The POS ASCII file is Gmsh’s old native post-processing format. Maybe I should let Frame3DD output in the curren...

Re: Generate a truss

After runing frame3dd, it genearets gmsh pos files which shows the orginal truss and deflection under each load case. This example only defined one load case.
These pos files could be viewed with gmsh.

畫線時按 Shift, 應可 畫出水平/ 垂直線
原来是shift键锁定,这个方便了一点。
没有construction line确实不方便。

snap是在那设置的呀?
看看這個
https://www.freecadweb.org/wiki/Draft_Snap/zh-cn
加载Arch, 工具条都在一行,拉到多行看到这个snap工具条了。画线时终于和录像显示的一样了。

FC有原点的功能么?比如在(0,0)处显示个十字。习惯从原点开始画了。

画线时全鼠标精确定位有点慢。如果输数字好像x,y都得输。以前用的软件是鼠标点第一个点后,按方向键确定第2点的方向,然后只输距离一个值就可以了。因为房子主要是水平和垂直线。

Re: 技巧請教:如何在零件上繪製連串形體

难点可能是在画复杂图形。画完了看需要不需要沿路径复制。
脊椎骨也得给张图纸,才能看能不能用fc画,如何画。没图纸,很难具体建议。
