Parametric Mounting Plate Design

Input width and height to automatically generate a mounting plate with resolved hole layout and output data.

Enter dimensions to automatically resolve plate geometry, hole count, spacing, and generated data.

InputsWidth, Height
Width Clamp80 to 480
Height Clamp40 to 240
Hole LogicLookup + spacing calculation

Automatic hole layout from plate dimensions

This geometry is generated directly from the same logic used in the workspace.

  • At 180 mm width: 6 holes with 32.8 mm spacing.
  • At 380 mm width: 10 holes with 40.44 mm spacing.

Change width and the layout updates automatically.

Width: 180 mm

Width: 380 mm

Increasing width steps hole count from 6 to 10 and recalculates spacing automatically.

These changes are reflected directly in structured output data.

Geometry and data stay aligned because they are generated from the same logic.

Inputs and outputs

Width and Height resolve the plate geometry and the reported results together.

Inputs

  • Width
  • Height

Outputs

  • Plate geometry
  • Hole count
  • Hole spacing
  • Generated data

Rule-driven plate sizing

A lookup table maps width to hole count, and the spacing calculation is encoded directly in the model.

Start with width and height

Width and Height drive the plate outline, the hole layout, and the generated data.

Clamp the design envelope

Width resolves between 80 and 480. Height resolves between 40 and 240 before geometry is drawn.

Select hole count from width

A width-based lookup table selects the hole count. At 180 mm width, the resolved hole count is 6.

Calculate hole spacing

Once width and hole count are resolved, spacing is calculated across the usable span automatically. At 180 mm width, spacing resolves to 32.8 mm.

Hole count lookup table

Hole count is not hard-coded into the geometry. The example reads a width-based lookup table and selects the appropriate quantity for the resolved width.

Max widthHole count
160 and below4
240 and below6
320 and below8
400 and below10
480 and below12

Resolved spacing logic

After width is clamped, the usable span is the plate width minus 16 mm. Hole spacing is then calculated by dividing that span across the resolved hole count.

That means the automatic hole spacing always reflects the current geometry and the current hole quantity. The plate stays consistent without manual recalculation.

Generated Data

The resolved plate produces usable engineering data that stays aligned with the geometry and can be exported directly.

Width, height, hole count, and hole spacing are available as generated data from the same evaluated model that draws the plate.

Exported data stays aligned with the visible result, so downstream schedules, validation, or reporting can use the same resolved values.

Manual drafting versus LogiDraft

A mounting plate shows the difference between geometry-only drafting and a rule-driven system that keeps geometry and data aligned.

Traditional manual drafting

Manual redraws and manual recalculation

  • Resize the plate and redraw the hole layout by hand.
  • Recalculate spacing separately whenever the width changes.
  • Keep output data in notes, spreadsheets, or downstream cleanup steps.
  • Accept that the drawing and the data can drift apart.

Rules drive geometry and outputs together

  • Width and Height resolve the plate geometry directly.
  • Hole count and automatic hole spacing update immediately from the same logic.
  • The same evaluated model exposes generated data alongside the drawing.
  • Geometry and outputs stay aligned because they come from one evaluated model.
