Scale Cross-Sections
Scale cross-sections
3-D FFS > From c-edges > Framew 
. >Scale cross-sections 
This function enables you to scale cross-sections and change the distance between cross-sections. The prerequisite is that the active part should contain a frame with closed parallel cross-sections.
- HiCAD calculates the approximate mesh volume and displays the value that it has calculated. Enter the new value and choose OK to exit the value input window .
- Select the scaling method:
- Between cross-sections
The cross-sections are moved, thereby changing the height of the component. - In
cross-section plane
The cross-sections are scaled. This changes the size of the part in the scaling area, i.e. the form of the component.
- Specify the scaling area by identifying two cross-sections. HiCAD marks the cross-sections of the selected scaling area and asks you to confirm the selected area. Only after you have confirmed this control prompt, is the scaling performed.

Scale cross-section sequence
3-D FFS > From c-edges > Framew . > Scale cross-section sequence 
You use this function to scale a sequence of cross-sections by specifying a surface calculation formula. Each cross-section of the sequence is scaled in such a way that it has the surface content predefined by the formula.
- Activate the frame.
- Call the function.
- Enter the surface calculation formula O(T).
- Specify the start and end values of parameter T. HiCAD automatically calculates the corresponding scaling factor from the specified intervalfor T and the calculation formula and displays it so that you can check it for each cross-section. You can confirm or, if necessary, correct the displayed value.
In the following figure, 1000 * EXP(T) has been selected as the calculation formula. The default setting 0.00 (start value) and 1.00 (end value) has been transferred for the start and end value of T. 10 cross-sections exist.
The cross-sections are scaled in guideline direction so that they have the following surface content:
1st cross-section: 1000
* EXP(T1) T1 = 0
nth cross-section: 1000 * EXP(Tn) Tn = (n-1)*(TEnd - TStart/No.C-S
- 1)
(n=2 to No.C-S)
where TEnd is the end value of T, TStart the start
value of T and No.C-S the number of cross-sections.
In the depicted example, this results in an increment of 1/9 for parameter T, given 10 cross-sections.
