Add members quickly by angle or relative position by tapping ‘R’

In addition to the traditional modelling methods in 構造3D, SkyCiv’s Relative Member function gives users yet another way to model their structures quicker and easier.

YouTubeでフォロー 時々, locating nodes or members in 3D space can get difficult, especially with complicated structures and members not orthogonal to the global axis’ (バツ, Y and Z axis). Users are able to take a single node and generate a member by projecting its other end node using a variety of different methods.

To use the 相対メンバー 関数, first select a node and either:

a) press ‘R’, または

b) Right Click node and select 相対メンバーを追加.

This will bring up a small pop-up that can me moved around the model space to best assist viewing as is shown below:

ここから, use the dropdown to select the method of adding the relative member and the input field to put in the required data. 主な方法は2つ (リリース, 長さ/角度) 相対メンバーの追加, これについては以下で説明します:

Adding a Relative Member using Global Axis Projection

の “Rel.” メソッドは、相対メンバーを追加するためのデフォルトのメソッドです. 入力フィールドに表示される 3 つの値 (デルタX, デルタ Y, デルタZ) correspond to the change in position from the selected node to the newly generated node. This is particularly useful for modeling in 3D space when you know the change in X, そして, and Z between the end points.

例:

If the selected node, say Node 1, is at the position (0,1,4) and you wanted to generate a member from Node 1 to a node at (10,12,8), say Node 2, you would put (10,11,4) as the values for (デルタX, デルタ Y, デルタZ). The projection to the new node will show as a dotted line:

Click the green check mark, または殴る 入る, to accept the generation of the member. The relative member window will stay up so you can chain multiple members in a row. If you choose to generate another member, the origin node will be Node 2, so the delta values will be relative to it, not Node 1.

Note in the image below, that while the dotted projection line is showing, it will display the member length, ペンツールを使用する場合と同様:

Adding a Relative Member using Angle and Length

This method allows users to quickly enter a member length and angle for a quick angled member. It is useful when modelling in 2D space and you know the angle and length of the member you wish to create. 水平からの角度を入力することで、選択したノードからメンバーを作成できます (反時計回り) そしてメンバーの長さ.

3D 空間でノードを生成するために使用できる平面は無数にあるため、, ユーザーは、3 つのグローバル軸平面のいずれかでこの方法を使用できます。: XY, YZ, とXZ. The two values shown in the input field of these three options (角度, 長さ) correspond to the angle in degrees from the horizontal and the length of the member, それぞれ.

例:

Lets say you want to generate an angled member in the XY plane originating from a node at (の,の,の), say Node 1. You know that the member sits at a 30 degree angle from the horizontal, in this case the X axis, and is 12 feet long. Select the node, press ‘R’ to bring up the 相対メンバー 関数. Click the dropdown and go to “XY”. Put in (30,12) 入力欄に, the projection will again show as a dotted line:

Click the green check mark, または殴る 入る, to accept the generation of the member. The relative member window will stay up so you can chain multiple members in a row. If you choose to generate another member, the origin node will be Node 2, so the delta values will be relative to it, not Node 1.

Adding Multiple Relative Members at the Same Time

The same 相対メンバー member function can not only be used to generate single members, but multiple at the same time. The workflow is the same, except users can select multiple nodes that they wish to generate relative members from. These nodes do not have to lie in the same plane and can be anywhere within the project.

例:

この例では, lets look a simple elevated platform which can be very easily generated using アセンブリテンプレート within Structural 3D. まず、Ctrl をクリックし、右から左にドラッグして一番上のものを選択します。 “床” ノードとメンバーの.

注意: の 相対メンバー function only generates members from nodes, メンバーからではなく.

今, create Relative Members using the “Rel.” 関数. 押す “R” to bring up the 相対メンバー 関数と入力 (10,10,2) デルタ値について. You will see that there is a projection line showing the member line in addition to the member length:

Click the green check mark to generate the members. You should see a member and node created for every node that was selected during the process.

The ability to add multiple Relative Members at the same time opens the doors for nearly unlimited modelling possibilities for users. Try it out next you are modelling a project.

Shift while using Relative Member Function

The last useful functionality located within the Relative Member function is “シフト”, which is the last item in the dropdown menu. This is a quick and easy shortcut to use the same Shift Nodes function, located in 編集する > 操作 > Shift Nodes. A single or multiple nodes can be shifted around in 3D space, and will stay connected to members. に似ています “Rel.” 関数, users must input the projection distances for each global axis’.

例:

Using the same elevated platform in the last example, repeat the selection of the same elements on the “top floor” of the platform. 押す “R” and find “シフト” in the dropdown. Type in the same values as before: (10,10,2). When using the Shift function, the projection line will not show because a new member is not being generated:

Click on the green check mark. All of the previous selected nodes will now move to the indicated location, moving the members as well:

注意: This can also be done with single nodes.
