Stab on constrained curve
Create stabs on a constrained curve
Stabs are helpful objects used to rappresent punches.
This command allows you to add a series of these stabs to the model parametrically, on a set of segments,
with two optional intersection that constrain it;
- Create the curve where the stabs will be placed by creating a constrained chain:
- 1.1 Select the segments you want to add to chain. Clicking twice on the same segment will remove the segment itself
- 1.2 Press Enter (or right click) to confirm the chain
- 1.3 Use the Pick start constraint button to select the first segment that will constrain the chain, and therefore the stabs
- 1.4 Use the Pick end constraint button to select the second segment that will constrain the chain, and therefore the stabs
- 1.5 Use the Add/remove item to the chain button to edit the selection of the segments.
- 1.6 Click Ok (or press space) when done
- Create the stabs selecting a method and filling in the options that are given.
- Click Ok (or press space) to confirm
- Distance based: select this method if the distance between the Stabs is the parameter that you want to control
- Number based: select this method if the Number of Stabs is the parameter that you want to control
- Distance from start: the distance, calculated from the start of the curve, from where the stabs series will begins
- Distance from end: the distance, calculated from the end of the curve, where the stabs series will finish
- You can also pick the start/end points on the curve using the corresponding buttons
- Offset value: the offset value is the distance from the target curve for a new curve where the stabs series will be created
- Radius: radius of each stab
- Flip button: if you are using an offset, use flip to move the stabs to the other side of the curve
Remarks on chains
- The chains infrastructure depends highly on the topology of the curve. For example,
you may need to click twice in parts of a closed curve that looks continuous but, since every curve
has a beginning and an end, the two parts are different segments.
- The selection of the constraining segments is optional
- To remove a constraining segment, use the right Pick start/end constraint button and deselect it
- It is possible to select the same segment as both start and end intersecting object.
In this case the chain will be constrained between the first and second intersection that it has with the segment.
- If one segment has multiple intersections with a curve, the one considered will be the closest to the selection point of the segment
- While selecting segments it is possible to use the undo (Ctrl + Z) function to remove the last
